Mach CNC software

2011-11-11T22:44:00.002+05:30

CNC Control Software is one of the fundamental things you will need to do CNC. The control software is what interprets the G-Code line by line and sends off commands to your machine controller.

Probably the standard in the hobby market is Mach. There are different versions: Mach1, Mach2 and Mach3. Mach is created by a company called Artsoft and has an excellent reputation in the marketplace. The software is easy to use and very powerful. The company also provides great service and is always working on the next generation of product.

I have used a couple other control software packages as well like CNC Pro, TurboCNC and Master. They seem a bit outdated compared to Mach, but serve their purpose and work well.

CNC Water Jet

2011-11-11T22:44:00.001+05:30

CNC Water Jet cutting is one way of cutting metals, glass or fabric. It is actually an abrasive cutting process where the cutting happens by eroding the material away. A stream of high-pressure water is focused on the material to make the cut. This jet is positioned and moved using CNC. An abrasive mixture is added to this high-pressure stream of water. The abrasive in the water jet does most of the cutting of the material.

I have found CNC Water Jet cutting to be an interesting process. As soon as you are done you need to dry or protect the recently cut edges. These edges will rust quickly in not handled properly. Before welding these edges usually need to be ground to prevent porosity in the weld.

CNC Tube Bender

2011-11-11T22:42:00.000+05:30

CNC Tube benders are a rarity compared with CNC Mills, CNC Lathes and CNC Routers. There aren’t too many hobbyists with one. Most often you will find them in Muffler Shops bending specific exhaust pipes from straight stock. An operator will feed the straight stock in, then the machine will bend it to varying angles at various points along the length.

The hobbyists I have heard of owning these machines usually work with Off Road Vehicles. They use these CNC Tube Benders to make roll cages, push bars, engine guarding and unique racing parts.

See the articles below for more information on CNC Tube Benders.

CNC Motion Control

2011-11-11T22:38:00.001+05:30

Motion control is a sub-field of automation, in which the position and/or velocity of machines are controlled using some type of device such as a hydraulic pump, linear actuator, or an electric motor, generally a servo. Motion control is an important part of robotics and CNC machine tools, however it is more complex than in the use of specialized machines, where the kinematics are usually simpler. The latter is often called General Motion Control (GMC). Motion control is widely used in the packaging, printing, textile and assembly industries.

Common control functions include:

Velocity control.

Position (point-to-point) control. There are several methods for computing a motion trajectory. These are often based on the velocity profiles of a move such as a triangular profile, trapezoidal profile, or an S-curve profile.

Pressure or Force control.

Electronic gearing (or cam profiling). The position of a slave axis is mathematically linked to the position of a master axis. A good example of this would be in a system where two rotating drums turn at a given ration to each other. A more advanced case of electronic gearing is electronic camming. With electronic camming, a slave axis follows a profile that is a function of the master position. This profile need not be linear, but it must be a mathematical function.

CNC export regulations

2009-10-21T15:40:00.002+05:30

What Is Restricted? There are three machine control features, or capabilities as referenced in the export regulations, that will cause a control to be restricted. All deal with path control and therefore target the more capable CNCs. Functions restricted are:
* More than four axis of simultaneously coordinated axes of motion.
* Real-time processing of CAD data in the CNC for tool path generation.
* Adaptive control with more than one machine condition monitored and fed back to the control for modifying the machining process.

The above restrictions existed under COCOM (Coordinating Committee for Multilateral Export Control) and were retained when the export regulations were restructured under the Wassenaar Arrangement effective November 1, 1996. The name Wassenaar comes from the city in Holland where the final agreement was signed. In the transition from COCOM to Wassenaar, the changes took emphasis off the control hardware and redirected it to the software. The result however is still the same, any CNC having one or more of the restricted capabilities is controlled and as such is subject to export licensing depending on the receiving country.
Why Are There Restrictions? The Wassenaar Arrangement was created by a multination group to replace the procedures that existed under COCOM. COCOM, which expired March 31, 1995, was also a multinational agreement formed in 1949 primarily to prevent U.S.S.R. and its satellite nations from obtaining sophisticated products that could be used to enhance its weapons capability. In its 46 years of existence COCOM had become grossly out-of-date as the landscape of our allies and enemies changed.
Under the Wassenaar Arrangement, Russia has become a member country and the targeted countries, which are not explicitly defined, are essentially pariah countries or "countries of concern." Each Wassenaar participating country is permitted to create its own actions based on "National Discretion." Presently the U.S. pariah countries are: Iran, Iraq, Libya, and North Korea.
What Technology Are We Protecting? Obtaining a U.S. export license for a CNC or a CNC controlled machine that has one or more of the restricted capabilities is a time consuming process that often causes delayed shipments and unhappy customers. In some cases, foreign customers have even stopped soliciting quotations from U.S. machine tool companies for the higher tech machines because of previous bad experiences consisting of delays and licenses turn downs. Instead they have gone to foreign manufacturers where the export rules are interpreted more liberally.

Why is it that the U.S. government risks the loss of export business by applying stricter interpretations to export regulations? It appears that the U.S. Department of Defense (DOD) is the motivating agency in this matter. DOD maintains that all three CNC restrictions are valuable capabilities when it comes to making small, very accurate parts associated with manufacturing nuclear weapons. DOD has been very consistent in their position that the machines with one or more of the three restricted capabilities would be of significant value to non-friendly countries for manufacturing weapon systems that are a threat to our national security.
It is up to the industries affected by export regulations to keep the pressure on government. One of the organizations involved in providing advice to government is the Department of Commerce's Materials Processing Equipment Technical Advisory Committee (MPETAC) which has been working for the past few years to educate government regulators about the changes and the availability of CNC controls. This committee referred to as a TAC committee is sponsored by the Department of Commerce and is chaired by Charles Carter, Vice President of Technology for The Association of Manufacturing Technology (AMT). The industry representatives serving on the TAC continue to work toward achieving a more realistic set of export regulations that will level the playing field with our allies when it comes to international trade.

CNC data interfaces

2009-10-21T15:35:00.002+05:30

It is not surprising that CNC Data interfacing is a source of confusion in many plants. The many names by which CNC data interfaces are specified have been a contributing factor. Some of the more common terms are: data port, serial port, communications interface, behind-the-tape-reader interface (BTRI), DNC interface, and parallel port, to name a few. These terms are often combined with vague definitions and written into equipment specifications. For example, the following definitions are taken from actual specifications: * "A serial data port is required for future connection into a DNC or FMS system." * "A serial or parallel data port is required. A BTRI is acceptable." * "The control must have MAP communications compatibility." * "An RS-232 interface is required." * "A DNC interface is required."
The ambiguity of the above statements allows the CNC vendor to comply without defining what capability will be provided. For example, an RS-232 interface can include a very sophisticated protocol that provides error checking and status reporting capability, or it may not have any of these capabilities.
One way to minimize confusion is to use the International Standards Organization (ISO) seven-layer network architecture for local area networks (LANs). Even though this architecture is a model for open systems interconnection (OSI) for LANs, it can also provide a common base of understanding for serial interfaces as well. The seven layers consist of: (1) physical, (2) data link, (3) network, (4) transport, (5) session, (6) presentation and (7) application.

When specifying a serial data interface there are three functions to be considered: (1) the connection, (2) the data-handling protocol and (3) the capability to be provided. The ISO seven-layer structure is used in the following description to explain these three functions:
Connection--This is the most basic part of the specification. It is the way the data is to be transmitted. Examples of the connections for serial interfaces are RS-232, RS-422 and RS-423. The speed or baud rate should also be stated at this level. Keep in mind however that even though each of the above standards provides a choice of baud rates, the distance which the data is to be transmitted becomes a limiting factor on achievable rates. Also, if error-checking protocol is to be employed, speed is usually sacrificed.
Protocol--Is a set of rules governing the exchange of messages between two communicating processes. For LANS like Manufacturing Automation Protocol (MAP) there is a protocol assigned for each of the seven ISO layers. For serial interfaces, the protocol normally only deals with starting and stopping the data flow, performing error checking if required and initiating the retransmission of a segment of data when there is an interruption. Example of protocols for serial interfaces are RS-491, RS-484, KERMIT, DDCMP and SNA. These may be isolated to ISO layer 2 functions or spread across multiple layers.
Capability--This layer is one that is most often ignored in users specifications. At this level the user should state what capability he expects the interface to have. Examples are: upload/download part programs, upload/download tool data, upload/download probe data, upload machine status, handle cycle start/stop over the data line, upload specified machine fault messages, and upload specific CNC fault messages.
In order to create an adequate interface specification it is necessary to define your requirements accurately. Include only the capability that is required since "standard" interfaces can add as much as $20,000 to the basic price of the control. Custom-designed interfaces can cost $100,000 or higher. This fact-of-life is the reason to stay with existing standard interfaces.
The above discussion was intended to address only the most significant points of serial data interfaces in CNCs. It is worth noting that all of the capability expected at the CNC data interface must also be implemented in the host computer if there is to be meaningful communications. It therefore becomes of utmost importance for the user to coordinate the communications requirements at both ends of the data line so that the proper interface tools exist when the time comes to use them.

Floods leaves over 2.5 million people homeless

2009-10-06T19:19:00.001+05:30

Heavy rains and floods over the past week have wreaked havoc in Karnataka, Andhra Pradesh, Maharashtra and left 2.5 million people homeless. The flooding, described by officials as the worst in many decades in south India, has killed some 280 people.
Over 50 villages in Andhra Pradesh on either side of river Krishna were inundated as a record 11 lakh cusecs of water reached Prakasam Barrage today even as week-long rains showed signs of abating in north Karnataka but the death toll mounted to 194.
At least five million people are crammed in temporary government shelters. Flood waters swamped millions of acres of cropland, including sugarcane plantations, prompting worries of a fall in sugar output in Karnataka, the country's third-biggest producer.
Rescue workers also moved more than 200,000 people living close to the river. An alert had been sounded in about 100 villages situated along the Krishna. Despite a lull in rains over the last 24 hours, the situation in flood-hit north Karnataka remains grim.
Karnataka Chief Minister B S Yeddyurappa has asked the Centre to declare the unprecedented rainfall and flood situation as a national calamity and has demanded the Centre to release 10,000 crore rupees for relief activities.
The situation has improved in Karnataka. State Chief Minister B.Y.Yeddyurappa announced that his government would construct over 2,00,000 houses for flood affected people.
In Andhra Pradesh, though the flood situation is improving in Kurnool and Mahaboobnagar districts, but hundreds of villages in Krishna, Guntur and Nalgonda are still inundated.
The state Government has announced an exgratia of Rs one lakh to the families of victims and immediate assistance in cash and kind to the families who lost their homes. (With inputs from Agencies)

CAMplete TruePath

2009-08-28T23:06:00.001+05:30

Have you ever wondered why tool paths look great on a CAM system but give different results on a milling machine? The answer is clear with CAMplete TruePath™.
In 5-axis production systems the only thing between CAM systems and machine tools is a post-processor. Yet most post-processors don't account for the complex, non linear motion unique to every machine. This leads to unpredictable tool motion, and large variations in cutting conditions leaving poor and inconsistent surface finish, gouging, increased tool wear and inaccurate results.

Taking the output from all popular CAM systems through APT or G-Code, CAMplete TruePath™ bridges the gap between CAM systems and milling machines. It is the "missing link." It provides everything needed to analyze, modify, optimize and simulate 5-axis tool paths in a seamless 5-view 3D environment.
TruePath's revolutionary design eliminates the need for a post-processor because the cutter path and G-Code are linked and design intent is communicated accurately to the machine tool.
Now, instead of blindly sending the output of a CAM system through a post-processor to a 5-axis machine, use TruePath™ to get it right the first time.

common gameplay elements

2009-08-28T23:02:00.000+05:30

The Command & Conquer games belong to the real-time strategy genre, with the exception of the first person shooter Command & Conquer: Renegade. A staple of the series is the parallel campaign's of various different factions to one central storyline. Games in the series also offered multiplayer game options, via LAN and modem connection. All games in the series have also offered online play.
All Command & Conquer real-time strategy games except Command & Conquer: Generals and its expansions have featured the "side bar" for navigation and control as opposed to many other similar games where the control bar is located on the bottom of the screen.
Command & Conquer gameplay typically requires the player to construct a base and acquire resources, in order to fund the ongoing production of various types of forces with which to assault and conquer the opponent's base. All available structures of the faction chosen by the player are constructed on-site at so-called "construction yard" - which typically begin as large-sized vehicles capable of deploying themselves into the aforementioned construction yards. When a construction yard has finished building a new structure, the player can select a spot near to a preexisting structure in order to place it, where the prefabricated building will then rapidly unfold in a distinctive manner.
In all games in the series except for Command & Conquer: Renegade and Command & Conquer: Generals and its expansion, Zero Hour, funds are acquired by specialized "harvester" units which bring their cargo (Tiberium for the Tiberian series of games or Ore for the Red Alert series) to a "refinery" structure. This in turn will convert the raw material into usable resources, expressed as credits. The raw materials themself requires storage space in the form of refineries and, in the case of excess, "storage silo" structures.
All factions have structures and units with similar functions at their disposal. However, they are adjusted to fit each faction's theme and have somewhat varying properties. Units can be classified into infantry, vehicles and aircraft, each with their own subdivisions (against infantry, vehicles, aircraft, structures, and combinations thereof). Unit effectiveness against opponents follows the rock-paper-scissors principle found in most real-time strategy games.
Virtually every type of structure in the series acts as a tech tree node, and additional units, structures and faction-specific abilities will become available as new structures are built and placed. Access to advanced units and abilities may be temporarily blocked if the required structures are destroyed, or if they are not being provided with adequate power by the supporting "power plant" structures.

command and conquer

2009-08-28T22:57:00.000+05:30

Command & Conquer (often abbreviated as C&C or CNC) is a video game franchise, mostly of the real-time strategy style as well as a first-person shooter game based on the former. The Command & Conquer series was initially developed by Westwood Studios between 1995 and 2003, with development being taken over by Electronic Arts with the liquidation of Westwood Studios in 2003.
The first installment of the series was released worldwide on August 31, 1995 and was simply named Command & Conquer. It was based on Westwood Studios' earlier strategy game Dune 2. The series is largely marketed for North American, European, and Australasian audiences, though many of the games have been translated into other languages including German, French, Spanish, Korean and Chinese. The series is primarily developed for personal computers running Microsoft Windows, although some titles have been ported to various video game consoles and the Apple Macintosh. The latter games of the series starting with Tiberium Wars have also been developed in parallel for Xbox 360. Another spin-off game, Command & Conquer: Red Alert 3, was developed for PC, Xbox 360, and PlayStation 3.
In 1999, American game marketer and developer Electronic Arts purchased Westwood Studios. Westwood was eventually closed down in 2003 and absorbed into EA Los Angeles which has become the current development center for the ongoing Command and Conquer series. Some of the original Westwood developer team remained at EA Los Angeles, but most left to form Petroglyph Games.
As of July 2009, the Command & Conquer franchise consists of eight games and ten expansion packs with sales of more than 30 million units worldwide.

3-D Touch Probes for 3rd Party Controls

2008-12-18T09:49:00.000+05:30

its 3-D touch trigger probes to make them available to be used on many CNC controls for milling, drilling and boring machines, and machining centers.
The company said its UTI 192 Universal Touch Probe Interface makes its probes compatible with CNC controls via a fast switching input.
The UTI 192 supports two lines Heidenhain 3-D touch probes, the TT tool touch probes and TS workpiece touch probes. This interface is designed to convert output signals of the Heidenhain 3-D touch probe to the machine control signals in accordance with IEC 61 131-2
Heidenhain said the probing functions that are actually available on the machine depend on the software cycles that are implemented in the respective control. The company offers cycles for automatic alignment and measurement of workpieces, workpiece presetting, and tool measurement on non-TNC controls.
The UTI 192 features a compact design, and can be fastened quickly on a standard mounting rail in the electrical cabinet. Heidenhain said it features a wide range of interfacing possibilities so that the touch probes can easily be connected to the different controls.

waterjet cutting

2008-12-18T09:42:00.001+05:30

Process Description
The waterjet cutting process uses a low volume, very thin stream of ultra high pressure water for cutting high precision parts. This thin stream of water leaves the cutting head at over twice the speed of sound, which is why it is able to cut such a wide variety of materials. The application of the waterjet cutting process can be further categorized into two separate processes - abrasive and non-abrasive cutting.

Waterjet Cutting (Non-Abrasive)
The waterjet cutting process begins with an ultra high pressure pump that can deliver water at pressures up to 60,000 PSI through a plumbing system to a cutting head. Inside the cutting head, a sapphire, ruby, or diamond orifice restricts the high pressure water flow to a diameter ranging from 0.002" to 0.025". This focused stream of supersonic water is capable of cutting rubber, plastics, food, insulation, cardboard, carpeting, and many other soft materials. As most of these materials are so easily cut, a large number of water jet systems purchased for cutting soft materials are configured with two or more cutting heads, thereby greatly increasing the production capability of the machine.

Waterjet Cutting (Abrasive)
Harder materials can be cut when an abrasive powder, such as garnet, is mixed in with the stream of water. The abrasive cutting head incorporates a mixing chamber below the orifice. The flow of high pressure water through this chamber creates a venturi effect, which in turn draws abrasive powder into the stream. This abrasive enriched waterjet stream is then re-focused by a mixing tube, which typically has an internal diameter between 0.020" to 0.050". The exiting abrasive stream produces a kerf width that is roughly the same size as the nozzle ID and is ideal for cutting aluminum, steel, titanium, granite, marble, composites, wood, glass and many other materials.

HEIDENHAIN Now Offers One of the Most Accurate 3-D Machine Tool Touch Probes in the Market Today

2008-12-18T09:39:00.001+05:30

With the introduction of the TS 740 infrared touch probe, HEIDENHAIN offers machine tool users the opportunity to perform measuring tasks that require an especially high probing accuracy and repeatability. Boasting a probing accuracy of ≤ ± 1 µm and a repeatability factor of 2 s ≤ 0.25 µm, the TS 740 workpiece touch probe is one of the most accurate 3D touch probes for machine tools in the market today.
To do this, the HEIDENHAIN TS 740 touch probe features a new sensor whose principle of function is completely different from that of the optical sensor of their standard touch probes. The new technology involves the use of three sensor elements. When probing a workpiece, the stylus is deflected so that a force acts on these elements. This results in the generation of charges that are detected by the electronics and converted into trigger signals. This system allows for more accurate results.
Also in spite of its low probing forces, the TS 740 is designed in such a way that it is well suited for use in modern machine tools with a fast tool changer. Rapid acceleration or deceleration does not cause uncontrolled trigger signals, as is common with those with low probing forces that are typically sensitive to mechanical disturbances.

A Tribute to John Bogstandard

2008-12-07T13:09:00.000+05:30

I've put together a bit of a tribute to the model steam turbine work of Bogstandard, who has contributed a number of articles on the HMEM boards. John is another of those rare guys who not only does fabulous work, but shares his methods in a way that makes it possible for all to learn. One of the most fascinating areas John worked in was that of model steam turbines. I'm quite sure I hadn't seen such a thing before coming across Bog's engines, but they sure look fun:

Faceplates for Eccentric Turning

2008-12-07T13:04:00.001+05:30

Over the years, some people have built special fixtures to make eccentric turning easier. It's common when building engines and other projects to have to do eccentric turning to create cams or crankshaft offsets. Here is one such faceplate that accomodates either a flat tooling surface or a v-block to hold the workpiece at various offsets

Getting Geared Up to Wire the Box

2008-12-07T13:01:00.001+05:30

I've been getting in a plethora of odds and ends to start wiring up the enclosure. I've now got everything except a relay I will use for the E-stop circuit and the master AC on/off switch for the front panel. I also did a number of versions of the overall schematic. The latest is on the enclosure page. Based on my latest schematics, I've done a layout for how I'll go about mounting the various sub-boards in the enclosure:
My goal this weekend would be to get the enclosure to the point I can actually mount the boards and begin the wiring process next weekend, and hopefully try spinning some servos (though not on the machine) next weekend as well. There's quite a bit of work to do there, but if I get enough hours I should reach that stage. Fingers crossed!
I still need to make an arm to support the keyboard and monitor, I need to mount the enclosure to the rolling cabinet, and I also need to paint it.
There's still a lot of fussing. I haven't spec'd or ordered any of the auxilliary panel connectors, for example. I have some sitting around the parts bin that will hopefully work. Have to look at them as well. If need be, I can delay VFD and coolant wiring until after the servos are running and it would be no big deal.

CNC Software integrates wtih CATIA V5.

2008-12-04T10:46:00.000+05:30

Irvine (CA) - Today CGTech announced the release of VERICUT 5.3, which features a tight integration with CATIA V5.

VERICUT is CNC machine simulation, verification and optimization software that enables users to eliminate the process of manually proving-out NC programs. It reduces scrap loss and rework. The program also optimizes NC programs in order to produce the most efficient tool paths possible that both save time and produce higher quality surface finish. VERICUT supports G-codes or native CAM output to simulate milling, drilling, turning, wire EDM, and mill/turn machining operations.

The CATIA V5-to-VERICUT Interface follows the successful VERICUT interface for CATIA V4, and provides a smooth upgrade path for CATIA users who have transitioned to CATIA V5.

"This is a significant enhancement for VERICUT software and the CATIA community," said Bill Hasenjaeger, Product Marketing Manager at CGTech. "The CATIA V5-to-VERICUT Interface tightly integrates the two programs to help users create the most accurate and efficient NC programs possible. It makes verifying and optimizing NC programs and simulating CNC machines a much easier and more efficient process."

Users can verify individual operations, a series of operations, or a set of complete NC programs. All stock, fixture, and design geometry is automatically transferred to VERICUT in the correct orientation, along with NC program, tooling, machine and control data and other simulation parameters.

VERICUT runs independently of the CATIA process, so you can continue working in CATIA version 5 while simulating and optimizing your NC programs. With VERICUT as your simulation package, you can also verify and optimize NC programs from other CAM systems in CL or post-processed G-code format.

VERICUT runs under Windows and UNIX. CGTech is the recognized world leader in CNC simulation, verification and optimization software technology for manufacturing. The California-based company has subsidiaries in the UK, Germany, France, and Japan, and resellers throughout the world.

2008-12-04T10:41:00.000+05:30

Founded in Massachusetts in 1984, CNC Software, Inc. is one of the oldest developers of PC-based CAD/CAM software and one of the first to introduce CAD/CAM software designed for both machinists and engineers. Mastercam, CNC Software’s main product, started as a 2D CAM system with CAD tools that let machinists create parts on a computer screen, as well as to machine parts in the shop. Since then, Mastercam has grown into the most widely used CAD/CAM package in the world (based on the number of installed seats, as reported by the independent research firm CIMData). CNC Software, Inc. is now located in Tolland, Connecticut.

Mastercam’s comprehensive set of predefined toolpaths—including contour, drill, pocketing, face, peel mill, engraving, surface high speed, advanced multiaxis, and many more—enable machinists to cut parts efficiently and accurately. Mastercam users can create and cut parts using one of many supplied machine and control definitions, or they can use Mastercam’s advanced tools to create their own customized definitions.

Mastercam also offers a level of flexibility that allows the integration of 3rd party applications to address unique machine or process specific scenarios.

Mastercam's name is a double-entendre: it implies mastery of CAM (computer-aided manufacturing), which involves today's latest machine tool control technology; and it simultaneously pays homage to yesterday's machine tool control technology by echoing the older term master cam, which referred to the main cam or model that a tracer followed in order to control the movements of a mechanically automated machine tool.

THE VISION THING

2008-11-01T16:01:00.001+05:30

Looking ahead, Mr. Burg and others predict that robotic vision technology promises to be the next emerging frontier in automaton. Instead of having a fixture that holds a part to be machined in a specific orientation so the robot knows where to pick it up, today’s automation cells include vision cameras to guide robots. Now operators can simply set a part on a conveyor with an accuracy of plus or minus an inch, and the robotic arm will seek, acquire and grip the part for loading.

Make no mistake; robotic vision technology existed in the mid-1980s. However, only recently have costs fallen to the point that including a camera and the associated software in a system is cost-effective. Vision capabilities that formerly cost in excess of $100,000 for hardware alone can now be brought online for a total cost of about $12,000. Furthermore, software advances have simplified system operations to the point that no special knowledge of programming or engineering is essential to successful operations.

As the metalworking industry becomes increasingly more competitive, more owner/operators are looking to robotics and automation for solutions to the pressures they face to remain productive and profitable. With the proliferation of manufacturers specializing in motion control, workhandling, tooling and software applications for CNC machine tool automation, there has probably never been a more advantageous time for medium- to small-size shops to evaluate a move to automation.

“Today there are viable and economical automation solutions in applications that just ten years ago may have been quite a stretch,” says Mr. Burg. “There is a wealth of expertise available in the marketplace to help shop managers make the transition to robotics. Affordable, off-the-shelf components that facilitate the process are widely available, and many shops have already begun the process of moving to automated CNC cell manufacturing. And, oh by the way—if you have not yet started to evaluate automation—keep in mind that your competitors probably already have.”

COST AND ROI

2008-11-01T16:00:00.002+05:30

While the ongoing development of machine tool and automation technology has done a remarkable job of keeping pace with industry’s increased demand for more reliable and productive systems, affordability remains as important an issue as ever. Naturally, today’s shop owners typically seek an accurate measure of the return they can expect on their investment in automation. Fortunately, they have at their disposal several sources of financial and technical guidance.

Evaluating the return on investment a shop owner can expect from a move to automation comes down to knowing the market for the parts that will be produced by the cell operation being considered. In fact, it is often the prospect of winning a large contract to machine significant quantities of identical or similar parts that encourages the managers of shops to consider automation in the first place. Of course, the cost of producing those parts is a critical factor in the calculations required to accurately project profitability.

Typically, shop owners can expect the transition to robotics and automation to entail a reasonable payback when a group of two or three machines are involved in the production of similar parts on a regular basis. Ideally, these machines should each have dedicated operators and be running at least two, if not three, shifts daily during the workweek. Even with the variable cost of labor from shop to shop, such a scenario is typically a candidate for a successful automation effort.

Another method of anticipating and evaluating the cost of moving to robotics is to apply a spindle-based calculation. Most owners usually find that when the cost of automating a spindle can be brought within the range of $50,000 per spindle, the time is usually right to make the move to automation. In other words, estimating the cost of a spindle at about $100,000, the projected cost of most successful automation efforts generally falls in the range of 50 percent of the cost of the CNC machine tool.

Of course, part weight, operator fatigue and other factors that put operators at risk of on-the-job injuries can skew calculations to the point that can justify even greater investments in robotics and automation. Fortunately, machine shop managers are not faced with making these decisions alone.

It is currently a trend for machine tool distributors to have both metalworking and automation expertise under one roof. A distributor like Ellison offers exactly this mix of services to its customers. “Typically, shop owners rely on their relationship with a distributor to gain the required access to any one of a number of automation suppliers or a third-party integrator who will then join the team to begin exploring solutions for a shop’s program.
“Some years ago, Okuma decided to climb the learning curve with the dedication of its Okuma Technology Institute,” Mr. Burg says. The Charlotte, North Carolina-based facility is home to Center for Advanced Manufacturing Technology. From the start, OTI worked with builders of systems ranging from conveyors and loaders to quality control and trend monitoring. “Today, those programs are the basis of the services that alter distributors without in house staff and resources can offer their customers.”

The interchange between members of the builder’s distributor network resembles a simplified version of the technology transfer efforts commonly seen on a global basis in contemporary high-technology industries. In practice, Mr. Burg and his team may work with an associate Okuma distributor in a remote location at the request of factory officials.

Working through OTI, Ellison Automation helps the associate Okuma distributor put in place the robotics and automation technology his customer requires. Conversely, if that customer has expertise in shaft turning for hydraulic components that Ellison lacks, that working knowledge can benefit customers in Illinois as the transfer of acquired process knowledge finds its way back through the OTI network to an Ellison customer.

STAYING POWER

2008-11-01T16:00:00.001+05:30

Most shops find that manually loaded machine tools are functional about 65 percent of the available time. On the other hand, users of automated machine tools can expect their machines to function more than 85 percent of the available time. As real as these numbers are, many shop owners contemplating the move to robotics often find them hard to comprehend.

Mr. Burg points out that managers of shops with four or five CNC machine tools can almost always accurately estimate the number of spindles running at any given time. However, that same task becomes daunting in a shop with 35 or 40 machine tools. In fact, he notes that while his team commonly finds one out of every two spindles down in shops this size, owner/operators doubt the numbers—until they walk the floor, often finding no more than one-third of all their machines making parts on a consistent basis.

“We tell owners, ‘You can put this process in control and automate it. Conservatively speaking, we’re going to give you one free spindle for every four on your shop floor.’ We feel comfortable saying this because with a good robot interface, it’s not at all uncommon for us to easily bring a shop up to 95 percent utilization,” Mr. Burg says.

In fact, today’s extremely reliable machine tools and off-the-shelf components have brought both the cost and availability of automated CNC machining within the reach of shops that only a decade ago might never have considered themselves viable candidates for automation. As recently as the mid-1980s, many early attempts to automate failed due to a combination of high development and installation costs.
Misapplication of robotics, marginally functional equipment, and unsuitable applications for robotics marked other early, but failed, attempts at automation. Simple errors like omitting gaging in automation systems doomed other early systems to fail. A combination of less-than-reliable tools and inconsistent parts with critical dimensions also meant failure.

CNC Robotics And Automation: Knowing When To Say 'When'

2008-11-01T15:54:00.001+05:30

In today’s competitive CNC manufacturing environment, the need for quality is a given, and job shops often win or lose contracts based on per-part costs that vary by just fractions of a cent. Naturally, the promise of achieving cost-efficient, consistent machining results through the use of robotics and automation is attractive to large metalworking concerns and small job shops alike. But many managers considering automation wonder if the time is right for a change. Or, they worry that quality will suffer if they dare to automate the processes they currently rely on for profits.

Like any successful business venture, the move to automation is best approached by following a sequence of orderly steps. Being sure the time is right to make the move to automation can be accomplished in an orderly fashion as well. In fact, there are a number of “machining milestones” any manager can use as a yardstick to gauge a shop’s readiness for robotics. The first of these milestones is the attainment of stability—inherent reliability in the machining process being considered for automation.

Naturally, most shop owners facing automation probably worry at least to some degree about the potential downside. However, many organizations making the switch to automated CNC machine tools find that quality actually increases with the change. Without exception, these shops share one important trait in common: the machining process they are automating has been reliable from the start. John Burg, Automation Division manager for Okuma distributor Ellison Machine Tools and Robotics (Warrenville, Illinois), agrees with this assessment.

"Even ISO 9000 is not strictly about quality,” he says. “It’s more about deciding how you are going to standardize a process, then following through and executing that process according to your standardized plan. That’s also the key to successful CNC machine tool automation. Once you get the process in control and standardize operations, superior quality naturally follows.”

Getting Set Up

Equally important is the need for establishing a controlled process for performing setup. Many owner/operators facing the move to automation are concerned that they’ll incur extra setup requirements to facilitate the use of robotics. In fact, many new users of automated machine tools find that setup time is actually reduced. This is true because once the process is controlled, it is no longer subject to time-consuming variables such as operator preference.

Imagine a part running on the same machine over three shifts daily. Every morning, Operator A sets up his material to the left of his CNC milling machine. At the start of the second shift, Operator B arranges inbound material to right. Later that evening, Operator C stays with B’s material setup but adjusts machining speeds and feeds according to personal preferences.

“I’ve actually walked into shops and found operators working different shifts using their own CNC programs to run exactly the same parts on the same machines,” Mr. Burg recalls. With automation comes the necessity for consistency and controlled setup and working processes. The advent of systematic operations that prescribe material flow, tool selection, chuck type, gripper details, and a host of other parameters also eliminates the type of counter-productive Operator A, B and C scenarios outlined.

The need to tame unbridled fluctuations in rates to keep production—and profits—consistent is another indicator pointing to an impending move to automation. Users of manually loaded CNC machine tools have historically come to expect production rates to vary widely from shift to shift and day to day. In fact, variations in similar processes can vary as much as 30 percent. With automated cells in place, owner/operators typically find that production rates vary less than 5 percent from one shift to another.

As an example, Mr. Burg cited one application that had 14 identical machines operating on a 7-second cycle time to machine aluminum substrate components for computer hard drives. The variations measured from machine operator to machine operator essentially reflected their individual dexterity. While some operators consistently ran more than 2,000 pieces in an 8-hour shift, others could turn out no more than 1,200 good parts.
With automation, the process on all 14 machines immediately produced 4,000 parts per shift. Results were consistent from machine to machine and shift to shift, with variations limited to increments of no more than one-half of one percent. Similarly, tracking spindle uptime as a measure of productivity is another indicator that can clearly point to the need to move to automation.

Automation can take the form of material and fixture storage capacity integrated into the machine load/unload capability. Random access for various parts is available for short run or

CNC MACHINING::IS IT TIME TO AUTOMATE?

2008-11-01T15:52:00.000+05:30

Machine shops seeking a more cost-effective method of CNC-machining should look to automation as a potential solution - and timing is everything.

Professionals in the automated CNC machining field suggest that automation can improve quality of machined parts, decrease setup time, stop fluctuations in production rates and raise the average percentage of functional machine tools in a shop from 65 percent to more than 85 percent.

However, before making the move to automation there are a few things to consider. First, the machining process selected for automation should be a reliable one from the onset in order to ensure the quality of automatically machined parts. Second, in order to ensure that the switch to automation will be cost effective, the price of automating each spindle should be less than $50,000 or about 50 percent of the cost of a spindle.

As the technology becomes more affordable, robotic vision seems to be the next frontier for CNC automation. One day soon, perhaps, machines equipped with vision technology will be able to guide themselves rather than having to rely on a fixture that holds a part to be machined in a specific orientation so that robots know where to pick it up. This will make it possible for operators to place an object on a conveyor within an accuracy of one inch and the robotic arm will seek, acquire and grip the part for loading.

CNC Machine Language
G-Code List

G-Code is one of a number of computer code languages that are used to instruct CNC machining devices what motions they need to perform such as work coordinates, canned cycles, and multiple repetitive cycles. Industry has standardized on G-Code as its basic set of CNC machine codes.

G-Code is the most popular programming language used for programming CNC machinery. Some G words alter the state of the machine so that it changes from cutting straight lines to cutting arcs. Other G words cause the interpretation of numbers as millimeters rather than inches. Some G words set or remove tool length or diameter offsets.

tool change scripting

2008-10-21T00:13:00.000+05:30

Tool changes are handled by a tool change script defined in the ToolChange.cfg file. This file should be edited in a standard Windows Text Editor. During a Tool Change, any valid GCode Block sequence can be executed. There are separate commands for picking up and putting back each tool so that each tool can be picked/placed at any location. If a tool is called for and there is not a valid tool section in the ToolChange.cfg file, then the last valid tool section defined will be executed.Example of a basic tool change script for Tool 1.[TOOL1]PLACE0=M05 (Turn Off Spindle)PLACE1=G4 P4 (Pause for Spindle wind down)PLACE2=G0 Z0.5 (Raise Z above Zero)PLACE3=G0 X7.000 Y4.770 (Move to a location for manual tool change)PLACE4=M0 (Wait for user to change tool and continue)PICKUP0=M03 (Turn on Spindle)PICKUP1=G4 P3 (Wait for Spindle wind up)Example of an advanced tool change script for Tool 1.[TOOL1]PLACE0=G49 (Turn Off TLO's)PLACE1=M05 (Turn Off Spindle)PLACE2=G4 P4 (Pause for Spindle wind down)PLACE3=G0 Z-.5 (Place tool in tool Holder - multiple movements)PLACE4=G0 X7.000 Y4.770 (Place tool in tool Holder - multiple movements)PLACE5=G0 Z-1.960 (Place tool in tool Holder - multiple movements)PLACE6=G0 X8.036 Y4.770 (Place tool in tool Holder - multiple movements)PLACE7=G0 Z-.5 (Place tool in tool Holder - multiple movements)PICKUP0=G49 (Turn Off TLO's)PICKUP1=G0 Z-.5 (Pick Up tool from tool Holder - multiple movements)PICKUP2=G0 X8.036 Y4.770 (Pick Up tool from tool Holder - multiple movements)PICKUP3=G0 Z-1.960 (Pick Up tool from tool Holder - multiple movements)PICKUP4=G0 X7.000 Y4.770 (Pick Up tool from tool Holder - multiple movements)PICKUP5=G0 Z-.5 (Pick Up tool from tool Holder - multiple movements)PICKUP6=M3 (Turn on Spindle)PICKUP7=G4 P3 (Wait for Spindle wind up)PICKUP8=G43 H1 (Use tool Length Offset for Tool 1)

We made our own board using the template from the web page. We used similar techniques to the one in part 4 of our iPod Superdock How-To. We reversed the pdf image using Gimp, and printed it onto a laserprinter transparency. This method doesn't create as nice of a trace as the paper, but it's speedier. Clean the board, and keep the paper backing between the plastic and the iron. Once the toner is ironed, just cool it with water and peel.

We etched the board using Ferric Chloride from RadioShack in a disposable Zip-Lock container. It needs to be warm and agitated to work well. The acid and hydrogen peroxide solution etches way faster.

We drilled the board with our drill press and tungsten carbide bits from Drill Bit City. We had to refer to the placement schematic several times to make sure we drilled everything right. Getting the pins holes aligned for the 5804s is a challenge!

If you want to do a toner transfer of the placement mask, do it before drilling the holes. Otherwise the surface is too uneven to allow a good transfer. If you screw it up like we did, you can cheat. Just print the mask onto a transparency and burn holes for the components with a soldering iron. It works surprisingly well.

Next time we'll start building the actual machine and show you how to build some simple and effective slide systems. For now, here's a teaser of what's coming! Good luck!

Finally, we'll need some linear slides. One easy out is to purchase a used or surplus XY table that's built just for this purpose. Custom designs can be built using ball bearings. Above is the linear rail that ShopBot uses. They machine the edge of a piece of steel and use this cool angled roller bearing.

We built this linear slide from a 1/2-inch steel rod and multiple bearing surfaces. It works, but we don't recommend building it if you value your sanity.

Once uou've bought or salvaged a set of motors, you'll need a controller. The controller provides the interface to the computer, drives the motors and can provide some simple feedback to the computer. The stepper controller has to be powerful enough to drive the motors you've selected. We sifted through lots of stepper controller designs looking for one that presented the best value. In the end we found this design for a relatively simple parallel port interface that originally appeared in a 1994 issue of Nuts and Volts. Today, the expensive UCN5804B is only available as a surplus item, but now the entire controller can be built for about $22-$30 in parts. (If you use a heavier motor like the ones from the Imagewriter, you might need to add some separate power transistors.)The parts list at the link is a bit outdated, here's our updated shopping list.

Most stepper motors are labeled. The major points of interest include the voltage, resistance and the number of degrees per step. Knowing the number of degrees per step is vital for configuring the software to properly control the machine later on. For a three axis machine, at the very least you'll want the X and Y axis to both have identical motors. It's not the end of the world if they don't match, but it's more of a pain later on.

The drive screw is the next piece of our project. Commercial units use linear ball screws or linear gears. The commercial parts aren't cheap, but you can get away with some 1/4-inch threaded rod from the hardware store. Instead of anti-backlash nuts, we'll use these handy 1-inch long 1/4-inch nuts. Just about every hardware store has them, and they produce very little play. Try out the hardware at the store because defects in the nut or rod will produce drag that's easily noticeable by spinning the nut on the rod.

To couple the rod to the motor shaft, we'll use vinyl tubing with a pair of collars. The tubing is 1/4-inch inner diameter and prevents binding by allowing some play between the rod and the motor. You can get suitable collars from a model airplane store (The hardware store had some, but they were overpriced). Alternatively, you can make your own like we did from nylon bushings and hex screws.

Parts Hunting For Part 1 of the How-To, we'll go over all the major components of the project and get started with the controller. The major components of the DIY CNC machine:

Stepper motors
drive positioning screw
3 Axis stepper motor controller
Linear slides

The most important component to determine the construction of your milling machine is the motor. Motors can be purchased from surplus houses, but the cheapest place to get them is from old dot matrix printers. Apple Imagewriters are one of our favorite sources. They contain multiple stepper motors, and the primary is pretty beefy. As a bonus, just about every dot matrix printer has a hardened steel rod that can be useful for our nefarious goals.

A stepper motor is an odd beast. Most motors spin when power is applied, stepper motors contain multiple coils. If the coils are energized in the proper order, the motor will rotate a small amount (a step). We'll take full advantage of the nature of stepper motors with this project. To simplify your life later on, you'll want to find stepper motors with more than four wires. Four wire motors are usually Bipolar motors. They produce more torque, but end up complicating the control circuit. The preferred type of motor for the frugal hobbiest is Unipolar. These usually have five or six wires, and they're pretty easy to work with.

how to build ur own cnc machine..part 1.

2008-10-14T22:02:00.002+05:30

Ready for some hard core gadget creation? If you thought your dremel tool was handy before, in today's How-To we'll start building our own CNC machine. Aside from the geek factor, it can be handy for making things like PC boards without chemicals or maybe some little styrofoam voodoo heads of all your enemies, uh friends.

Gentlemen, start your soldering irons.

Computer controlled mills have been around for a long time. If you just want to buy oneone, Sherline makes mills that are ready to go (pictured is their CNC ready model -- just add your own motors and controller). But then again, if you wanted to buy one, you probably wouldn't be reading this, now would you? A CNC machine is a lot like a precision drill press with a table that moves in two directions -- seeing a commercial unit like the one above should help you visualize the end goal. We'll be making ours from scrounged, recycled, and adapted parts; today we'll be going over the basic parts we'll need to build our own.

working of cnc machine tools

2008-10-12T08:43:00.001+05:30

The CNC machines are of various types such as Lathe, Drilling, Milling, Boring, etc. In the traditional methods these machines are operated by the operators, but in the CNC machines you have to just feed the program of various cutting and final dimensional instructions. The computer understands these instructions and operates the machine, much like the robot. The CNC machines can operate in two different ways.
In the first method the drawings of jobs that are to be made are given to the CNC machine programmer. He makes a program in a language, also called programming language, understood by the computer. To make sure that the final product will be of the desired shape and the size, one job can be made on the trial basis, though this step is not always necessary. Then the programmer can also choose the number of such parts that are to be made.
If it is a single job, the CNC machine will stop automatically after finishing the job. However, if there are more jobs, the machine will pick up the next job and follow all the machining instructions as already fed into the computer. For this purpose you should keep the raw material ready at particular location. In this way the CNC machine will keep on working continuously without wasting any precious time. The whole of the CNC machine is a sort of the Robot; in fact the technology of working behind both is same.
The second method is even more automated and is based on the concept of CAM- Computer Aided Manufacturing. In many productions shops the series of CNC machines may be combined into one station, commonly called a "cell”. This is to progressively machine a part requiring several operations. The CAM software helps in designing the product and also checking its feasibility on the computer itself. When the design is finalized, the final dimensions of the products are directly fed into the computer of the CNC machine without the need of making the drawing or complicated instructions. Thus, what you get is the final product that you have designed just a few moments ago.
The present day CNC machines can work all the days of the week and 24 hours a day continuously without any human intervention. The advanced machines are also equipped with the error detection facilities that enable the machine to call the operator’s mobile in case of emergency like broken tool, no jobs, no oil in the machine, or any other faults. Meanwhile the machine will keep on performing the other operations that it could still perform. It is surprising to know that these machines can keep on making thousands of jobs for days together without feeling the need of any operator.

CNC LATHE

2008-10-12T08:37:00.000+05:30

CNC Lathe and turningCNC lathes are rapidly replacing the older production lathes (multispindle, etc) due to their ease of setting and operation. They are designed to use modern carbide tooling and fully utilize modern processes. The part may be designed by the Computer-aided manufacturing (CAM) process, the resulting file uploaded to the machine, and once set and trialled the machine will continue to turn out parts under the occasional supervision of an operator. The machine is controlled electronically via a computer menu style interface, the program may be modified and displayed at the machine, along with a simulated view of the process. The setter/operator needs a high level of skill to perform the process, however the knowledge base is broader compared to the older production machines where intimate knowledge of each machine was considered essential. These machines are often set and operated by the same person, where the operator will supervise a small number of machines (cell). The design of a CNC lathe has evolved yet again however the basic principles and parts are still recognisable, the turret holds the tools and indexes them as needed. The machines are totally enclosed, due in large part to Occupational health and safety (OH&S) issues. With the advent of cheap computers, free operating systems such as Linux, and open source CNC software, the entry price of CNC machines has plummeted. For example, Sherline makes a desktop CNC lathe that is affordable by hobbyists. Most CNC Swiss style lathes today utilize two spindles. The main spindle is used with the guide bushing for the main machining operations. The secondary spindle is located behind the part, aligned on the Z axis. In simple operation it picks up the part as it is cut off (or parted off) and ejects it into a bin, eliminating the need to have an operator manually change each part, as is often the case with standard CNC turning centers. This makes them very efficient, as these machines are capable of fast cycle times, producing simple parts in one operation in as little as 10-15 seconds. This makes them ideal for large production runs of small diameter parts.

The INTEGREX e-RAMTEC V/8 is doted with a ram spindle, whose cutting heads are automatically changed by the ATC to do deep I.D. turning and I.D. angle head drilling.This CNC machinig center was disigned for aircraft, ships, construction machinery and other large items to vertical lathe-based development of complex machining, in addition to the usual set up a dedicated spindle machining diameter of the shaft so that the diameter can not change tooling for processing.The axis distance reach 900 MM and has a 40 collection tools, performing a long time task, along with the cars and milling function.There is no need to change the tooling, which minimize the processing time for instance before you'd needed 1oo hours of processing now you only need 12 hours to complete a mechanical task and the precision has increades as well.This smart machine can detect thermal deformation and prevent mechanical interference, can inspect the center of gravity position.

CNC ROUTERS

2008-09-18T10:03:00.002+05:30

A router is a woodworking tool used to rout out (hollow out) an area in the face of a piece of wood. It was a tool particularly used by pattern makers and staircase makers and consisted of a broad-based wooden hand plane with a narrow blade projecting well beyond its base plate gaining it the nickname Old Woman's Tooth. Since about 1960, it has been replaced by the modern spindle router, which was designed for the same work, although the first electric hand routers appeared in the years just after World War I. Further refinement produced the plunge router, invented by Elu (now part of deWalt) in Germany in the late 1940s. This is even better adapted for many types of work. Today, traditional hand-powered routers are often called router planes. Modern routers are often used in place of traditional moulding planes or spindle moulder machines for edge decoration (moulding) of timber. Related to the router, is a smaller lighter version designed specifically for trimming laminates. It can be used for smaller general routing work. For example with an appropriate jig it can be used recessing door hinges and recessing lock faceplates etc. A wood CNC Router is similar to a metal CNC mill with the following differences:The wood router typically spins faster — up to 24,000 RPM It typically uses smaller tools — typical shank size 20 mm or at most 25 mm. It typically uses smaller toolholders MK2 (Morse taper #2 - on older machines),ISO-30, HSK-63 or the tools just get held in a collet tool holder affixed directly to the spindle nose. ISO-30 and HSK-63 are rapid-change toolholding systems. HSK-63 has begun to supplant the ISO-30 as the rapid change standard in recent years Some wood routers have multiple separate heads that can come down simultaneously or not. This design is generally not as easy as a toolchanger with ISO-30 or HSK-63, though it is easier to maintain. A wood router table is controlled in the same way as a metal mill, but there is a lot of CAM software specifically for wood routers. Wood with different grain must be approached with unique strategies, and wood CAM software is less likely to need to have hog-out strategies than the metal ones. Wood routers are frequently used to machine other soft materials such as plastics at high speed.

ALL ABOUT THE LATEST MOBILE TECHNOLOGY

2008-08-08T17:52:00.000+05:30

A guide to the latest in mobile communications technologyFrom the heavy cordless phones of the 1980's to the smart phones of today, cellular phone technology has undergone a tremendous change.But have you ever wondered how you can call someone across the world using a tiny phone? You might have heard of features like WAP and GPRS from cell phone vendors and service providers. But are you aware of what they really mean?Rediff Guide to the Net has compiled a guide to make you familiar with today's mobile technologies. So next time you go to buy a phone, you know exactly what they're talking about.Generations of mobile communicationsThe first generation (1G) of mobile communications was introduced in the late 1970s; it was primarily used for voice transfer. In the early 1990s, second generation (2G) systems came into existence and was further developed to 2.5G, which includes GSM, TDMA and CDMA. These were used for voice and data.The next generation of mobile communications is 3G and this delivers data speeds from 384 kbps to 2 Mbps and over wireless interfaces such as GSM, TDMA and CDMA.Mobile phone access technologiesFrequency division multiple access (FDMA)The first-generation analog mobile access method; FDMA uses separate frequencies for each call. For example if there are four stations, each will receive their own frequency. Thus there is no interference between them. This reduces interference, but limits the number of users.Time division multiple access (TDMA)TDMA allocates unique time slots to each user within each channel, thus allowing many users to access the radio frequency without anyone's interference. Each mobile conversation uses only a particular frequency slot of the time. More information on TDMACode division multiple access (CDMA)Commercially introduced in 1995 by Qualcomm, CDMA quickly became one of the world's fastest-growing wireless technologies. 3G CDMA networks provide more capacity for voice traffic, along with high-speed data capabilities, hence many cellular service providers are now building or upgrading to it.CDMA is used in both 2G and 3G wireless technologies. Indian Cell operators like Reliance IndiaMobile, TATA Indicom, BSNL and MTNL's Garuda all use CDMA2000 technology and its variant CDMA1x. More Information and White papers on CDMA Faqs on CDMAGlobal system for mobile communications (GSM)Developed on TDMA protocol in Europe, GSM is now the worldwide standard technology for mobile communications. The advantage of GSM is that it provides a high level of security, globally accepted technology standards and superior sound quality.For any GSM phone to work, it requires a Subscriber Identity Module (SIM), a card that contains your telephone account information. Thus, an Indian GSM phone can be used in USA and other countries too.Faqs on GSMWireless technology platforms: GPRS, EDGE and WAPWhat is GPRS?GPRS, short for General Packet Radio Services, is an enhancement to GSM technology that integrates GSM and IP technology. GPRS offers an always-on, high speed connectivity to the Net. Thus you can check your email on the move and surf the Web at high speeds. Currently BPL Mobile and Hutch (Orange in Mumbai) offer GPRS services in India.Faqs on GPRSWhat is WAP?In this hi-tech age, people on the move need any-time access to the Net. This is where WAP comes in. It provides Internet access to cell phones. It is an open standard for wireless protocols that is independent of the service providers. To display Web content, the cell phone must have a WAP browser. Nowadays, cell phones often come with WAP and GPRS technology.WAP and GPRS also allows you to download games, send mail and even transfer your messages to your PC.More information on WAPWhat is EDGE?The new EDGE ((Enhanced Data GSM Environment) interface has been developed specifically to meet the bandwidth needs of 3G. Promoted by Ericsson, it offers high-speed data transfers over GSM networks with just a software upgrade to the handset. EDGE allows speeds up to 384 kbps.More information on EDGE

CNC PLASMA CUTITING MACHINE

2008-08-03T14:56:00.000+05:30

Plasma cutting is a process used to cut steel and other metals (or sometimes other materials) using a plasma torch. In this process, an inert gas (in some units, compressed air) is blown at high speed out of a nozzle; at the same time an electrical arc is formed through that gas from the nozzle to the surface being cut, turning some of that gas to plasma. This plasma is sufficiently hot to melt the metal and moving sufficiently fast to blow molten metal away from the cut. The result is very much like cutting butter with a hot jet of air. Plasma cutters have also been used in CNC machinery. Manufacturers such as Retro Systems and Plasma CAM build CNC cutting tables, some with the cutter built in to the table. The idea behind CNC tables is to allow a computer to control the torch head making clean sharp cuts. Modern CNC plasma equipment is capable of multi-axis cutting of thick material, allowing opportunities for complex welding seams on CNC welding equipment that is not possible otherwise. For thinner material cutting, plasma cutting is being progressively replaced by laser cutting, due mainly to the laser cutter's superior hole-cutting abilities. A specialized use of CNC controlled Plasma Cutters has been in the HVAC industry. Software will process information on ductwork and create flat patterns to be cut on the cutting table by the plasma torch. This technology has enormously increased productivity within the industry since its introduction in the early 1980's. A typical HVAC cutting machine is Plasma Automation's Vicon Cutting Table Plasma cutters use a number of methods to start the pilot arc, depending on the environment the unit is to be used in and its age. Older cutters use a high voltage, high frequency circuit to start the arc. This method has a number of disadvantages, including risk of electrocution, difficulty of repair, sparkgap maintenance, and the large amount of radio frequency emissions. Plasma cutters working near sensitive electronics, such as CNC hardware or computers, use the contact start method. The nozzle and electrode are in contact. The nozzle is the cathode, and the electrode is the anode. When the plasma gas begins to flow, the nozzle is blown forward. A third, less common method is capacitive discharge into the primary circuit via a Silicon Controlled Rectifier. PC: plasma cutting machines also plasma systems cutting or plasma.

MULTI-AXIS MACHINE FOR MASS PRODUCTION

2008-08-03T14:48:00.000+05:30

It's called "The Pinnacle of Mass-Production". Up to 3 turrets can be installed, all of them Built-in Motor Turret (BMT™). By placing the motor inside the turret, heat generation and vibration are reduced to a minimum and transmission efficiency is improved. Cutting performance, speed and precision are also increased. The previous model worked with a transmission structure with many heat-generating parts such as gears and belts, which affect machining accuracy, but the new nz series tourret works with a built-in motor, there is no transmission structure. The sources of heat are reduced, and the motor is also surrounded by a cooling jacket.

The new NZ Series of cnc multi-axis machines offers not only turning, but also excellent milling with the Y-axis. With the longest Y-axis stroke in its class, it achieves high-precision, high-efficiency machining.Mori Seiki's original technology, the Octagonal Ram Construction (ORC™), is a fundamental improvement on the weaknesses of conventional moving structures. With the symmetry of an octagonal shape, thermal displacement is controlled and stable straightness is ensured even at high speeds. It offers stable, high-precision machining.

The cnc's engeniers had achieved both high flexural rigidity and a light body by making repeated use of the most advanced analytical techniques. They've used Finite Element Method (FEM) analysis to simulate the structure's deformation under load. By making fine adjustments to every detail, from the thickness of the bed to the shape and arrangement of the ribs, they achieved high fl exural rigidity. At the same time, we managed to make the body light.From Moriseiki's official website.http://www.moriseiki.co.jp

CNC PLASMA CUTTER

2008-08-03T14:38:00.000+05:30

A lot of people enter the CNC Field by wanting to know more about CNC Plasma Cutting. Most have used a plasma cutter and found it to be a valuable tool. Then the question comes up, can a machine drive this tool around a table to cut out a part. The answer is yes, and it is pretty easy to do.
CNC Plasma Cutters can vary by quite a lot in size. The can go from Giant Plate Burning units that cut 2” thick steel, to sheet metal, high definition units that are about as accurate as a laser. As plasma cutters have come down in price so have CNC Plasma Cutter. There is one unique thing about plasma cutting compared with other CNC Machine you will come across. You have to do something about the dust they put out.

CNC SAFETY STEPS

2008-08-03T14:37:00.000+05:30

No need for any long introductions, this section is a must for all machine shops! Remember, It doesn’t have to be you!
SAFETY GLASSES IN THE SHOP.
Even when you’re not working on a machine, you must wear safety glasses. A chip from a machine or a piece of dirt from a blast of an airhose could fly into your eye.
IF YOU HAVE LONG HAIR OR A LONG BEARD, TIE IT UP.
If your hair gets caught in a spinning machine … you WILL be pulled INTO the machine.
NO LOOSE CLOTHING/JEWELRY.
Ties, watches, loose sleeves, necklaces etc., none of these objects are worth the price of a limb. As a instructor I’m often asked about wedding rings, all I can say is that if I were married … I would value that ring …. and remove it.
WEAR APPROPRIATE SHOES.
Wear shoes that give a sure footing. If you are working with heavy objects, steel toes are highly recommended.
SAFE CONDUCT.
Be aware of what’s going on around you. For example, be careful not to bump into someone while they’re cutting on a machine. (they could lose a finger or worse!). Concentrate on what you’re doing. Don’t hurry. If you catch yourself rushing, slow down. Don’t push speeds and feeds!! You’ll end up damaging your part, the tools, and maybe the machine itself. Listen to the machine, if something doesn’t sound right, turn the machine off. Don’t let someone else talk you into doing something dangerous, and NEVER attempt to measure a part that’s moving.

HOW CNC WORKS??

2008-08-01T23:49:00.000+05:30

How CNC works
There is another article included in this web site called The Basics of CNC that explains how to program, setup, and operate CNC machines in greater detail. Additionally, we offer a series of products aimed at helping you learn how to use CNC machines. Here we're relating how CNC works in very general terms.
As you might already have guessed, everything that an operator would be required to do with conventional machine tools is programmable with CNC machines. Once the machine is setup and running, a CNC machine is quite simple to keep running. In fact CNC operators tend to get quite bored during lengthy production runs because there is so little to do. With some CNC machines, even the workpiece loading process has been automated. (We don't mean to over-simplify here. CNC operators are commonly required to do other things related to the CNC operation like measuring workpieces and making adjustments to keep the CNC machine running good workpieces.)
Let's look at some of the specific programmable functions.
Motion control
All CNC machine types share this commonality: They all have two or more programmable directions of motion called axes. An axis of motion can be linear (along a straight line) or rotary (along a circular path). One of the first specifications that implies a CNC machine's complexity is how many axes it has. Generally speaking, the more axes, the more complex the machine.
The axes of any CNC machine are required for the purpose of causing the motions needed for the manufacturing process. In the drilling example, these (3) axis would position the tool over the hole to be machined (in two axes) and machine the hole (with the third axis). Axes are named with letters. Common linear axis names are X, Y, and Z. Common rotary axis names are A, B, and C.
Programmable accessories
A CNC machine wouldn't be very helpful if all it could only move the workpiece in two or more axes. Almost all CNC machines are programmable in several other ways. The specific CNC machine type has a lot to do with its appropriate programmable accessories. Again, any required function will be programmable on full-blown CNC machine tools. Here are some examples for one machine type.
Machining centers
Automatic tool changer
Most machining centers can hold many tools in a tool magazine. When required, the required tool can be automatically placed in the spindle for machining.
Spindle speed and activation
The spindle speed (in revolutions per minute) can be easily specified and the spindle can be turned on in a forward or reverse direction. It can also, of course, be turned off.
Coolant
Many machining operations require coolant for lubrication and cooling purposes. Coolant can be turned on and off from within the machine cycle.
The CNC program
Think of giving any series of step-by-step instructions. A CNC program is nothing more than another kind of instruction set. It's written in sentence-like format and the control will execute it in sequential order, step by step.
A special series of CNC words are used to communicate what the machine is intended to do. CNC words begin with letter addresses (like F for feedrate, S for spindle speed, and X, Y & Z for axis motion). When placed together in a logical method, a group of CNC words make up a command that resemble a sentence.
For any given CNC machine type, there will only be about 40-50 words used on a regular basis. So if you compare learning to write CNC programs to learning a foreign language having only 50 words, it shouldn't seem overly difficult to learn CNC programming.
The CNC control
The CNC control will interpret a CNC program and activate the series of commands in sequential order. As it reads the program, the CNC control will activate the appropriate machine functions, cause axis motion, and in general, follow the instructions given in the program.
Along with interpreting the CNC program, the CNC control has several other purposes. All current model CNC controls allow programs to be modified (edited) if mistakes are found. The CNC control allows special verification functions (like dry run) to confirm the correctness of the CNC program. The CNC control allows certain important operator inputs to be specified separate from the program, like tool length values. In general, the CNC control allows all functions of the machine to be manipulated.
What is a CAM system?
For simple applications (like drilling holes), the CNC program can be developed manually. That is, a programmer will sit down to write the program armed only with pencil, paper, and calculator. Again, for simple applications, this may be the very best way to develop CNC programs.
As applications get more complicated, and especially when new programs are required on a regular basis, writing programs manually becomes much more difficult. To simplify the programming process, a computer aided manufacturing (CAM) system can be used. A CAM system is a software program that runs on a computer (commonly a PC) that helps the CNC programmer with the programming process. Generally speaking, a CAM system will take the tediousness and drudgery out of programming.
In many companies the CAM system will work with the computer aided design (CAD) drawing developed by the company's design engineering department. This eliminates the need for redefining the workpiece configuration to the CAM system. The CNC programmer will simply specify the machining operations to be performed and the CAM system will create the CNC program (much like the manual programmer would have written) automatically.
What is a DNC system?
Once the program is developed (either manually or with a CAM system), it must be loaded into the CNC control. Though the setup person could type the program right into the control, this would be like using the CNC machine as a very expensive typewriter. If the CNC program is developed with the help of a CAM system, then it is already in the form of a text file . If the program is written manually, it can be typed into any computer using a common word processor (though most companies use a special CNC text editor for this purpose). Either way, the program is in the form of a text file that can be transferred right into the CNC machine. A distributive numerical control (DNC) system is used for this purpose.
A DNC system is nothing more than a computer that is networked with one or more CNC machines. Until only recently, rather crude serial communications protocol (RS-232c) had to be used for transferring programs. Newer controls have more current communications capabilities and can be networked in more conventional ways (Ethernet, etc.). Regardless of methods, the CNC program must of course be loaded into the CNC machine before it can be run.
Types of CNC machines
As stated, CNC has touched almost every facet of manufacturing. Many machining processes have been improved and enhanced through the use of CNC. Let's look at some of the specific fields and place the emphasis on the manufacturing processes enhanced by CNC machine usage.
In the metal removal industry:
Machining processes that have traditionally been done on conventional machine tools that are possible (and in some cases improved) with CNC machining centers include all kinds of milling (face milling, contour milling, slot milling, etc.), drilling, tapping, reaming, boring, and counter boring.
In similar fashion, all kinds of turning operations like facing, boring, turning, grooving, knurling, and threading are done on CNC turning centers.
There are all kinds of special "off-shoots" of these two machine types including CNC milling machines, CNC drill and tap centers, and CNC lathes.
Grinding operations of all kinds like outside diameter (OD) grinding and internal diameter (ID) grinding are also being done on CNC grinders. CNC has even opened up a new technology when it comes to grinding. Contour grinding (grinding a contour in a similar fashion to turning), which was previously infeasible due to technology constraints is now possible (almost commonplace) with CNC grinders.
In the metal fabrication industry:
In manufacturing terms, fabrication commonly refers to operations that are performed on relatively thin plates. Think of a metal filing cabinet. All of the primary components are made of steel sheets. These sheets are sheared to size, holes are punched in appropriate places, and the sheets are bent (formed) to their final shapes. Again, operations commonly described as fabrication operations include shearing, flame or plasma cutting, punching, laser cutting, forming, and welding. Truly, CNC is heavily involved in almost every facet of fabrication.
CNC back gages are commonly used with shearing machines to control the length of the plate being sheared. CNC lasers and CNC plasma cutters are also used to bring plates to their final shapes. CNC turret punch presses can hold a variety of punch-and-die combinations and punch holes in all shapes and sizes through plates. CNC press brakes are used to bend the plates into their final shapes.
In the electrical discharge machining industry:
Electrical discharge machining (EDM) is the process of removing metal through the use of electrical sparks which burn away the metal. CNC EDM comes in two forms, vertical EDM and Wire EDM. Vertical EDM requires the use of an electrode (commonly machined on a CNC machining center) that is of the shape of the cavity to be machined into the workpiece. Picture the shape of a plastic bottle that must be machined into a mold. Wire EDM is commonly used to make punch and die combinations for dies sets used in the fabrication industry. EDM is one of the lesser known CNC operations because it is so closely related to making tooling used with other manufacturing processes.
In the woodworking industry
As in the metal removal industry, CNC machines are heavily used in woodworking shops. Operations include routing (similar to milling) and drilling. Many woodworking machining centers are available that can hold several tools and perform several operations on the workpiece being machined.
Other types of CNC machines
Many forms of lettering and engraving systems use CNC technology. Waterjet machining uses a high pressure water jet stream to cut through plates of material. CNC is even used in the manufacturing of many electrical components. For example, there are CNC coil winders, and CNC terminal location and soldering machines.
Job opportunities related to CNC
There is quite a shortage of skilled people to utilize CNC machines. And the shortage is growing. Everywhere I go I hear manufacturing people claiming that they cannot find skilled people. Unfortunately, it has also been my experience that pay scales have not yet reflected this shortage. Even so, you can make a good wage and develop a rewarding career working with CNC machines. Here are some of the job titles of people working with CNC machine tools.

WHAT IS CNC??

WHAT IS CNC??

CNC stands for Computer Numerical Control and has been around since the early 1970's. Prior to this, it was called NC, for Numerical Control. (In the early 1970's computers were introduced to these controls, hence the name change.)
While people in most walks of life have never heard of this term, CNC has touched almost every form of manufacturing process in one way or another. If you'll be working in manufacturing, it's likely that you'll be dealing with CNC on a regular basis.
Before CNC
While there are exceptions to this statement, CNC machines typically replace (or work in conjunction with) some existing manufacturing process/es. Take one of the simplest manufacturing processes, drilling holes, for example.
A drill press can of course be used to machine holes. (It's likely that almost everyone has seen some form of drill press, even if you don't work in manufacturing.) A person can place a drill in the drill chuck that is secured in the spindle of the drill press. They can then (manually) select the desired speed for rotation (commonly by switching belt pulleys), and activate the spindle. Then they manually pull on the quill lever to drive the drill into the workpiece being machined.
As you can easily see, there is a lot of manual intervention required to use a drill press to drill holes. A person is required to do something almost every step along the way! While this manual intervention may be acceptable for manufacturing companies if but a small number of holes or workpieces must be machined, as quantities grow, so does the likelihood for fatigue due to the tediousness of the operation. And do note that we've used one of the simplest machining operations (drilling) for our example. There are more complicated machining operations that would require a much higher skill level (and increase the potential for mistakes resulting in scrap workpieces) of the person running the conventional machine tool. (We commonly refer to the style of machine that CNC is replacing as the conventional machine.)By comparison, the CNC equivalent for a drill press (possibly a CNC machining center or CNC drilling & tapping center) can be programmed to perform this operation in a much more automatic fashion. Everything that the drill press operator was doing manually will now be done by the CNC machine, including: placing the drill in the spindle, activating the spindle, positioning the workpiece under the drill, machining the hole, and turning off the spindle.

LATHE CENTER

A lathe center (or center) is a tool that has been ground to an included angle of 60 ° and is used to accurately position a workpiece about its axis.[citation needed]
The primary use of a center in metalworking is to ensure concentric work is produced, this allows the workpiece to be transferred between operations without any loss of accuracy. A part may be turned in a lathe, sent off for hardening and tempering and then ground between centers in a cylindrical grinder. The preservation of concentricity between the turning and grinding operations is crucial for quality work. A center is also used to support longer work pieces where the cutting forces would deflect the work excessively, reducing the finish and accuracy of the workpiece, or creating a hazardous situation.
A center has applications anywhere that a centered workpiece may be used, this is not limited to lathe usage but may include setups in dividing heads, cylindrical grinders, tool and cutter grinders or other related equipment. The term between centers refers to any machining operation where the job needs to be performed using centers.
A center is inserted into a matching hole drilled by a center drill.

SCREW MACHINE

SCREW MACHINE

A screw machine is a metalworking machine used in the high volume manufacture of turned components.
In operation, a screw machine is similar to a lathe. Essentially a screw machine is an automated turret lathe.
Screw machines have been replaced by CNC lathes to some extent. However, for high volume production of turned components nothing is as cost efficient as a screw machine.
In the hierarchy of manufacturing machines, the screw machine sits at the top when large volume of product is needed. An engine lathe sits at the bottom, taking the least amount of time to set-up but the most amount of skilled labor and time to actually produce a part. A turret lathe has traditionally been one step above a lathe, needing greater set-up time but being able to produce a higher volume of product and usually requiring a lower skilled operator once the set-up process is complete. Screw machines may require an extensive set-up but once running, a single operator can monitor the operation of several machines.
The advent of the CNC lathe or more properly: the CNC turning center, has blurred these distinct levels of production to some extent. The CNC turning center most appropriately fits in the mid-range of production, replacing the turret lathe. However, it is often possible to produce a single component with a CNC turning center more quickly than can be done with an engine lathe. To some extent too, the CNC turning center has stepped into the region traditionally occupied by the screw machine. The ease of set-up of CNC machinery makes it attractive alternative to the screw machine. However, in nearly all cases, a screw machine, once set-up, can outperform any other turning machine in speed and cost of production.
As CNC components and controllers have matured, CNC has moved into the world of screw machines as well. Multispindle CNC screw machines have opened up possibilities for producing a number of parts per hour that was not obtainable before. CNC screw machines and rotary transfers are a recent, and highly expensive manufacturing option. The number of axes which must be controlled can number over a hundred, and as a result, programming is highly complex. The costs in initial purchase and tooling plus ongoing programming costs relegate this flexible, high-end piece of equipment to only the largest manufacturing operations.

HISTORICAL OVERVIEW OF CNC MACHINE

2008-07-28T10:36:00.000+05:30

HISTORICAL OVERVIEW

CNC was preceded by NC (Numerically Controlled) machines, which were hard wired and their operating parameters could not be changed. NC was developed in the late 1940s and early 1950s by John T. Parsons in collaboration with the MIT Servomechanisms Laboratory. The first CNC systems used NC style hardware, and the computer was used for the tool compensation calculations and sometimes for editing.
Punched tape continued to be used as a medium for transferring G-codes into the controller for many decades after 1950, until it was eventually superseded by RS232 cables, floppy disks, and now is commonly tied directly into plant networks. The files containing the G-codes to be interpreted by the controller are usually saved under the .NC extension. Most shops have their own saving format that matches their ISO certification requirements.
The introduction of CNC machines radically changed the manufacturing industry. Curves are as easy to cut as straight lines, complex 3-D structures are relatively easy to produce, and the number of machining steps that required human action have been dramatically reduced.
With the increased automation of manufacturing processes with CNC machining, considerable improvements in consistency and quality have been achieved with no strain on the operator. CNC automation reduced the frequency of errors and provided CNC operators with time to perform additional tasks. CNC automation also allows for more flexibility in the way parts are held in the manufacturing process and the time required to change the machine to produce different components.
