Analysis:
Experts predict that the competition of machinery manufacturing industry in 2 1 century is essentially the competition of numerical control technology.
? k？ K On June 5438, 2002+10/October 29 +20021October 8, the CNC Vocational Education and Training Group of the National CNC System Engineering Technology Research Center of Huazhong University of Science and Technology conducted a survey on the teaching and training work, the equipment used and the needs of CNC technical talents in more than ten schools (mainly vocational and technical colleges) in Northeast China, Jiangsu, Shanghai and Zhejiang. Details are as follows:
? k？ A, CNC talent market demand
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, a limited number of CNC machine tools (mostly imported products) in China have not been fully utilized. There are many reasons, among which the lack of CNC 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？ K CNC talent demand is mainly concentrated in the following enterprises and regions:
? k？ K 1, large and medium-sized state-owned enterprises, especially military enterprises with good economic benefits and major national equipment manufacturing enterprises. Military manufacturing industry is the main application object of numerical control technology in China.
Hangzhou power generation equipment factory can't recruit CNC operators with a monthly salary of 6000.
? k？ K2。 With the rapid development of private economy, there is a shortage of numerical control talents in 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 mold technicians with CNC knowledge has reached 300,000 yuan, exceeding the "doctor".
? k？ K Second, the knowledge structure of CNC talents
? k？ K There are two main sources of CNC talents in the production line now: first, graduates majoring in mechatronics or CNC technology application in universities, higher vocational schools and secondary vocational schools are very young, with different levels of basic theoretical knowledge of English, computer application, mechanical and electrical, and certain practical ability, and are easy to accept the challenges of new jobs. Their biggest flaw is the technical experience that the school can't provide. At the same time, due to the narrow division of school education courses, 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 training of CNC technology at different levels to meet the urgent needs of enterprises for CNC talents. These people generally have the technical 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 the computer application technology and computer numerical control system.
? k？ K for CNC talents, there are three levels of demand, and the required knowledge structure is also different:
? k？ K 1, 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 organizing training in secondary vocational schools. There is a great market demand for this kind of personnel, and they are suitable to be CNC machine tool operators in the workshop. But because of his simple knowledge, his salary will not be high.
? k？ K2, gray collar layer
? k？ K 1) NC programmer: master the knowledge of NC machining process and operation of NC machine tools, master the professional knowledge of complex mold design and manufacturing, and master three-dimensional 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. Suitable for CNC programmers in 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) CNC machine tool maintenance personnel: 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 electromechanical debugging and maintenance of CNC machine tools. Suitable for organizing training in higher vocational colleges. It is suitable for engineers and technicians in the equipment department of the factory. 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 a lot of practical experience accumulation. At present, it is very scarce and the treatment is high.
? k？ K3, gold collar layer
? k？ K NC generalist: Have and master the comprehensive knowledge required by NC operators, NC programmers and NC maintenance 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 is well paid. Suitable for the cultivation of undergraduate and higher vocational colleges. However, special training measures and the guidance of famous teachers are needed to promote their success. Suitable for being the technical director of an enterprise or the electromechanical design director of CNC machine tool product development in a machine tool factory.
? k？ K above all kinds of CNC talents, the main basic knowledge is basically the same, and the content and focus of professional courses are different. In the course setting, we should especially strengthen the content of practical training with enterprises.
