The numerical control technology of Dongguan numerical control processing plant is the technology that uses digital information to control the mechanical movement and working process. The numerical control equipment is the mechatronics product formed by the penetration of new technology represented by numerical control technology into traditional manufacturing industry and emerging manufacturing industry, namely the so-called digital equipment, Its technical scope covers many fields: Dongguan CNC machining plant (1) mechanical manufacturing technology（ 2) Information processing, processing and transmission technology（ 3) Automatic control technology（ 4) Servo drive technology（ 5) Sensor technology（ 6) Software technology, etc. The development trend of numerical control technology the application of numerical control technology has not only brought revolutionary changes to the traditional manufacturing industry, making the manufacturing industry a symbol of industrialization, but also with the continuous development of numerical control technology and the expansion of application fields, it plays an increasingly important role in the development of some important industries (it, automobile, light industry, medical treatment, etc.) of the national economy and people's livelihood, Because the digitization of equipment required by these industries has been the trend of modern development. From the development trend of numerical control technology and equipment in the world, the main research hotspots are as follows
