When filling in the college entrance examination, what are the employment directions of CNC technology majors and what are the employment prospects are of great concern to the majority of candidates and parents and friends.

The CNC technology major cultivates technical application talents who master the basic knowledge and basic theory of CNC technology application, have the ability to program and operate CNC machine tools, engage in modern production organization and management of CNC machining technology, and develop morally, intellectually and physically.

This major cultivates all-round development of morality, intelligence, physique and beauty, has good professional ethics and humanistic qualities, masters the reading and compilation of mechanical parts drawing and mapping, CAD three-dimensional modeling design, mechanical processing process document reading and compilation, familiar with safety operation procedures, various metal cutting processing methods and processing equipment, common parts programming methods and processing and other basic knowledge of car Zheng Tang, with CNC machine tool operation, CNC machining programming, CAD cam software technology application and other capabilities, engaged in CNC machine tool operation and programming, High-quality technical and skilled personnel in CNC machining technology preparation, CNC machine tool maintenance and commissioning, production management, etc.

CNC technology is a set of mechanical, electrical, hydraulic, optical, computer, automatic control technology as one of the knowledge-intensive technology, it is the manufacturing industry to achieve modernization, flexibility, integrated production basis, but also to improve product quality, improve productivity of the indispensable material means. Japan, the United States, Germany and other industrially developed countries using numerical control technology to obtain economic benefits roughly as follows: operators reduced by 50, cost reduced by 60, machine tool utilization rate up to 60-80, the number of machine tools reduced by 50, production area reduced by 40.

Due to the wide application of CNC technology in the world's manufacturing industry, ordinary machinery is gradually replaced by high-efficiency and high-precision CNC equipment.

The wide application of numerical control technology in the machinery manufacturing industry has become a powerful driving force for the development of the national economy. After joining the WTO, with the rapid development of the economy, China is gradually becoming the "world manufacturing center", and the numerical control rate has become one of the important indicators to measure the manufacturing technology level and economic strength of a country or enterprise (numerical control rate: the proportion of CNC equipment in the number of equipment owned).

At present, the numerical control rate of machine tools in China is only, while Japan is as high as 30, and the United States is more than 40. CNC machine tools have been widely used in developed countries, and the application and promotion of CNC technology in China is far behind that of developed countries. China will increase 40-500,000 CNC machine tools in a few years, and 60-800,000 CNC professional and technical personnel will be needed accordingly.

The above is the introduction of CNC technology, I hope to help you!

1. Numerical control technology, referred to as numerical control, is the technical monitoring technique that uses digital control to achieve automatic control of a certain working process. It usually controls mechanical quantities such as position, angle, velocity, etc., as well as switching quantities related to the direction of mechanical energy flow. The generation of numerical control depends on the emergence of data carriers and binary form data operations.

2. This major cultivates all-round development of morality, intelligence, physique and aesthetics, has good professional ethics and humanistic qualities, masters the mechanical parts drawing and mapping, CAD three-dimensional modeling design, mechanical processing process document reading and preparation, familiar with safety operation procedures, various metal cutting processing methods and processing equipment, common parts programming methods and processing and other basic knowledge, with CNC machine tool operation, CNC machining programming, CAD cam software technology application and other capabilities. High-quality technical and skilled personnel engaged in CNC machine tool operation and programming, CNC machining process preparation, CNC machine tool maintenance and commissioning, production management, etc.

It's up to you to get there. If you want to become a top master in the CNC industry, you may encounter problems in the future if you have no mathematical foundation, especially if you want to do design or something, and you can't calculate the preparation, it doesn't seem to work! But it doesn't necessarily matter how big the impact is, for example, if you are just an operator, then you have a strong foundation in mathematics in elementary and junior high school!

If you want to learn programming, it's not a big problem, it's all software doing the calculations, as long as it's not a super complex part, it shouldn't be a big problem. So, if you want to, just go ahead and learn, no problem. Learn professional courses well, such as drawing and programming.

If you only want to be a senior blue-collar worker, then it's not a big problem, my trigonometric function is also a half-ass, maybe not as good as you, I learned CNC, did drills, and now programming and the like. I don't feel that the impact is great, and I really can't say it, I can also ask my colleagues or compare people, and I usually work and not exams.

Then again, now sometimes it feels like the industry is just a chicken rib, a bit tasteless, and it's a pity to lose it. I am tired from work, and the salary is not good, five or six thousand is quite high in Sichuan. It's the kind of kind that can't starve to death and can't make a fortune.

It is impossible to rely on this entrepreneurship, one is that the order is particularly difficult to find, the second is that the comprehensive technology is difficult to master, and finally one is the most difficult, those equipment, ordinary machine tools are tens of thousands of second-hand starts, if it is a CNC machine tool, it is two or three hundred thousand.

Maybe you can also look to see if there is a better major. Professionally, it depends on the ease of employment, the amount of money, the size of labor intensity, development prospects, and the possibility of starting a business independently. Personal opinion, for reference only.

After these years of development, especially the development of science and technology, as well as the crisis of previous years, it is not easy to do now.
