After China's entry into WTO, China is becoming a "world processing and manufacturing center", and the country attaches great importance to the shortage of talents for numerical control technology application. Six ministries and commissions, including the Ministry of Education and the Ministry of Labor and Social Security, have designated the cultivation of CNC technical talents as "the national talent cultivation project in short supply". At present, China has the largest number of machine tools in the world, of which only 2% are CNC machines. To make it reach 10%, a large number of CNC machine tool operators, programmers and maintenance personnel are needed to enrich this industry. People usually call CNC programming technicians and maintenance personnel "gray collars", and even call senior CNC technicians "golden collars", which means that this industry has high wages and good employment.
