What is a CNC program?

① CNC is what a major

CNC is a technology to automate machine tool processing with digital information.

This technology uses computers to perform logical control functions on the movement trajectory of the equipment and peripherals according to the control program stored in advance.

As a result of the use of computers to replace the original hardware logic circuits composed of CNC devices, so that the input operating instructions for storage, processing, arithmetic, logic judgment, and other control functions can be achieved through the realization of computer software to complete the processing of micro-commands generated by the servo-driven device to drive the motor or hydraulic actuators to drive the equipment operation.

Cultivation goals: CNC professional is to cultivate mastery of CNC technology and application of the basic theory, basic knowledge, can be engaged in the production of the first line of production, management, product marketing, equipment maintenance and other work needs of the application of senior technical personnel.

In the late 1990s, the emergence of the PC + CNC intelligent CNC system, that is, the PC for the control system hardware part of the PC installed on the NC software system, this way the system is easy to maintain, easy to realize the network manufacturing.

⑦ What is the specialty of CNC

The specialty of CNC is still very broad for now. There is no one and operating this belongs to

⑧ CNC professional specifically include what professional

CNC technology, referred to as CNC (Numerical Control). It is the use of digital

digital information on the machine tool movement and machining process control method. With the implementation of numerical control technology processing control of machine tools, or machine tools equipped with a numerical control system is called numerical control (NC) machine tools. NC system includes: numerical control device, programmable controller, spindle drive and feed device and other parts. CNC machine tool is a highly integrated product of machine, electricity, liquid, gas and light. To realize the control of the machine tool, the need for geometric information to describe the relative motion between the tool and the workpiece as well as process information to describe the machine tool processing must have some process parameters. For example: feed rate, spindle speed, spindle forward and reverse, tool change, coolant switching, and so on. This information in a certain format to form a processing file (i.e., normally said CNC machining program) stored in the information carrier (such as disk, perforated paper tape, tape, etc.), and then by the machine tool on the CNC system reads (or directly through the CNC system's keyboard input, or through the communication mode input), through the decoding, so that the machine tool action and machining of parts. Modern CNC machine tool is a typical product of mechatronics, is a new generation of production technology, computer-integrated manufacturing systems and other technical basis.

The development trend of modern CNC machine tools is high-speed, high-precision, high reliability, multi-functional, composite, intelligent and open structure. The main development trend is the development of software and hardware with an open structure of intelligent full-featured universal CNC device. CNC technology is the basis of automation of machining, CNC machine tools is the core technology, its level is related to the national strategic position and reflect the level of the country's comprehensive strength. It develops with the development of information technology, microelectronics technology, automation technology and detection technology. CNC machining center is a kind of CNC machine tool with a tool magazine and can automatically change the tool, the workpiece can be in a certain range of a variety of machining operations. Machining parts in the machining center is characterized by: the machined parts after a clamping, the CNC system can control the machine tool according to different processes to automatically select and replace the tool; automatically change the machine tool spindle speed, feed and tool relative to the trajectory of the workpiece and other auxiliary functions, continuous machining surfaces of workpieces are automatically drilling, countersinking, reaming, boring, tapping threads, milling, and other multi-process processing. As the machining center can centralize and automatically complete a variety of processes, to avoid human error, reduce the workpiece clamping, measurement and machine tool adjustment time and workpiece turnover, handling and storage time, greatly improving the processing efficiency and machining accuracy, so it has a good economic efficiency. Machining centers can be divided into vertical machining centers and horizontal machining centers according to the location of the spindle in space.

Many students want to learn CNC technology, because it is felt that this is a direction of development, learning this seems to be more promising, better to find a job. Then, what should be learned, from where to start down to learn? Means is to serve the purpose, because everyone's purpose of learning is different, the answer to the above question is certainly more than one. I can only generalize.

1. Classroom knowledge should be learned. The knowledge in the university classroom may not be the latest, but it must be the most systematic, and it is far from being old and dying. Generally speaking, old age is the price at which knowledge can be systematized. If you don't go through the classroom and learn directly in the real world, you may learn the newest and most practical knowledge, but it is always a partial one, and you can't recognize it as a whole. Therefore, the content of the university classroom still must be learned.

2. To more contact with the actual. University life contact with the actual opportunity is relatively small, near the time of graduation there is a production internship, can be considered to the production line to go, but also only allowed to see is not allowed to touch. This situation is difficult to change. Only from a side to try to make up for it: we are good at learning book knowledge, then learn the most close to the actual book knowledge.

3. What is the most practical book knowledge? Textbooks are hardly, newly written ones maybe, but many are not. The most practical book knowledge is actually for the commercial interests of the product description and instructions for use, these are the closest to the actual. If you do go into CNC technology after graduation, it's these products that you use, and pretty much the whole thing you have to do is to choose from among them the one that best suits your application. Selecting and using these products, and developing them yourself when possible, is pretty much the entire job of the person working in CNC.

4. What products are used in CNC?

A: controllers (control cards), motors, screws, rails, scales (encoders), PLC. seems to be all of them. I'm here to list what I think is the best or most commonly used products, give their URLs, give the way to find information, have time and energy, you just go ahead and look at it, the sea of learning, there is no end to the day, but be sure to find the right direction, look at the most worthwhile to look at the information.

Controller: general-purpose bed with can use Siemens controllers, such as 802S, 810D, 840D, etc., you can download information from the Siemens website, Chinese or English.

Specialized beds can be used control card, the best one seems to be PMAC, the largest one seems to be GALIL. PMAC's information can be downloaded from the website of Yuanmaoxing company, galil's information can be downloaded from the Baolun company's website, it seems to have some Chinese information, but most of them are in English. You can also use the control card from Gugo, the advantage is that all the Chinese information (user manual, installation manual, programming manual, etc.).

AC servo motor: good expensive Siemens, cheap Panasonic, Yaskawa. You can go to the Siemens website, there is Chinese information.

Screw guide: the best is THK, there is Chinese information.

Grating encoder: Heidenhain's website to download product samples, there is Chinese information.
