K On October 29th, 22 and November 8th, 22, the research group of CNC vocational education and training of the National CNC System Engineering Technology Research Center of Huazhong University of Science and Technology conducted a series of investigations on the teaching and training work, the equipment used and the demand for CNC technical talents in more than ten schools at all levels (mainly vocational and technical colleges) in Northeast China, Jiangsu, Shanghai and Zhejiang. The details are as follows: K? K 1. What is the market demand for CNC talents? K In developed countries, CNC machine tools have been widely used. There is a big gap between China's manufacturing industry and international advanced industrial countries, and the numerical control rate of machine tools is less than 2%. At present, the limited number of numerical control machine tools (mostly imported products) in China have not been fully utilized. There are many reasons, among which the lack of numerical control talents is undoubtedly one of the main reasons. Because numerical control technology is the most typical and widely used mechatronics technology, China urgently needs a large number of technical talents at all levels from research and development to use and maintenance. K? The demand for K CNC talents is mainly concentrated in the following enterprises and regions: K? K1. Large and medium-sized state-owned enterprises, especially the military enterprises with good economic benefits and major national equipment manufacturing enterprises. The military manufacturing industry is the main application object of CNC technology in China.

Hangzhou Power Generation Equipment Factory can't recruit CNC operators with a monthly salary of 6, yuan. K? K2. With the rapid development of private economy, numerical control talents are in short supply in China's economically developed coastal areas (such as Guangdong, Zhejiang, Jiangsu and Shandong), mainly concentrated in mold manufacturing enterprises and auto parts manufacturing enterprises.

The annual salary of a mold mechanic with CNC knowledge has reached 3, yuan, which is more than that of a doctor. K? K Second, the knowledge structure of CNC talents K? K There are two main sources of CNC talents who are now in the front line of production: first, graduates majoring in mechatronics or CNC technology application in universities, higher vocational schools and secondary vocational schools, who are very young, have different degrees of basic theoretical knowledge of English, computer application, machinery and electricity and certain practical ability, and are easy to accept the challenges of new jobs. Their biggest defect is the technical experience that the school can't provide. At the same time, due to the narrow division of professional courses in school education, it is still difficult to meet the requirements of some enterprises for compound talents with integrated processing and maintenance. K? Another source of K is to select people from the existing employees of enterprises to participate in short-term and medium-term training of CNC technology at different levels to meet the urgent need of CNC talents in enterprises. These people generally have the technological background and rich practical experience needed by enterprises, but most of them are graduates of traditional mechanical or electrical majors at all levels, with narrow knowledge, especially those who don't know much about computer application technology and computer numerical control system. K? K for CNC talents, there are three levels of demand, and the knowledge structure they need to master is also different: k? K1, blue-collar layer: K? K CNC operator: proficient in machining and CNC machining process knowledge, proficient in the operation and manual programming of CNC machine tools, and familiar with automatic programming and simple maintenance of CNC machine tools. Suitable for organization and training in secondary vocational schools. There is a large market demand for such personnel, and they are suitable as CNC machine tool operators in the workshop. However, because of his simple knowledge, his salary will not be high. K? K2, gray collar layer k? K1) NC programmer: master the knowledge of NC machining process and the operation of NC machine tools, master the professional knowledge of complex mold design and manufacturing, and master 3D CAD／CAM software, such as uc and ProE. Proficient in numerical control manual and automatic programming technology; Suitable for higher vocational and undergraduate schools to organize training. It is suitable to be a NC programmer in the factory design department and process department. This kind of personnel is in great demand, especially in the mold industry. The treatment is also higher. K? K2) Maintenance and repair personnel of CNC machine tools: master the mechanical structure and electromechanical debugging of CNC machine tools, master the operation and programming of CNC machine tools, and be familiar with the characteristics, software and hardware structures, PLC and parameter settings of various CNC systems. Proficient in mechanical and electrical debugging and maintenance of CNC machine tools. Suitable for organizational training in higher vocational colleges. Suitable for engineering and technical personnel in the factory equipment department. The demand for such personnel is relatively small, but it is very difficult to train such personnel, which requires a wide range of knowledge structure, strong ability to adapt to CNC-related work, and requires a lot of practical experience accumulation. At present, it is very scarce and its treatment is high. K? K3, gold collar layer k? K CNC generalist: Possess and master the comprehensive knowledge required by CNC operators, CNC programmers and CNC maintenance and repair personnel, and have accumulated a lot of practical experience in practical work, with a wide range of knowledge. Proficient in the mechanical structure design of CNC machine tools and the electrical design of CNC system, and master the electromechanical alignment of CNC machine tools. Can complete the selection of CNC system, the design, installation, debugging and maintenance of electrical system of CNC machine tools. Can independently complete the numerical control transformation of machine tools. He is a sought-after talent in enterprises (especially private enterprises), and his treatment is very high. It is suitable for the training of undergraduate and higher vocational schools. However, it is necessary to provide special training measures and the guidance of famous teachers to promote their success. Suitable for being the technical person in charge of an enterprise or the electromechanical design director of CNC machine tool product development in a machine tool factory. K? K For all kinds of CNC talents above, the main basic knowledge is basically the same, and the content and focus of professional courses are different. In terms of curriculum, we should especially strengthen the content of practical training and internship with enterprises < P > I wish you success in your studies and a happy life.
