Numerical control technology, also called CNC (Computerized Numerical Control), is a technology that uses computers to realize digital program control. This technology uses a computer to perform the logical control functions of the equipment motion trajectory and the peripheral equipment operation sequence according to the pre-stored control program. Because the computer is used to replace the original numerical control device composed of hardware logic circuits, various control functions such as storage, processing, calculation and logical judgment of input operation instructions can be realized through computer software, and the micro-instructions generated by processing are transmitted to the servo drive device to drive the motor or hydraulic actuator to drive the equipment to run. Numerical control specialty is to cultivate applied senior technical talents with good political and ideological quality, all-round development of morality, intelligence, physique and aesthetics, adapt to the needs of socialist market economy, master the basic theory and knowledge of numerical control technology and application specialty, and engage in production, management, product marketing and equipment maintenance in the production line.

3. CNC technical personnel demand situation
The scale, type, level and quality of the demand for CNC technical talents depend on the development level and level of the national economy and manufacturing industry, as well as the management requirements and development trend of the employer itself. According to statistics, CNC machine tools in Germany, the United States, Japan and other developed countries account for more than 70% of production equipment, and there is a big gap between China's manufacturing industry and international advanced industrial countries. According to the statistics of Machinery Association, the number of CNC machine tools in China's manufacturing industry is currently less than 2% of the total, and it has been growing at a rate of more than 35% in recent years, and the limited number of CNC machine tools in China has not been fully utilized. Although there are many reasons, the lack of CNC talents is undoubtedly one of the main reasons.
With the further promotion of manufacturing information engineering, the use of high-tech and advanced applicable technologies to transform and upgrade traditional industries, improve the level of technical equipment and product competitiveness of enterprises, and the large-scale numerical control of manufacturing equipment, the demand for numerical control technicians in society has further increased.
