At present

the rapid development of intelligent manufacturing industry makes the openness and intellectualization of numerical control technology more obvious

and our country pays more attention to numerical control technology

which will effectively promote the automation and intellectualization of industrial manufacturing in our country. The paper summarized the development status and development trend of CNC technology in China

analyzed the existing gap between the domestic CNC technology and intelligent manufacturing development level and the international advanced technology. The development of CNC technology is the embodiment of a country’s manufacturing capability and level

combining big data and artificial intelligence

CNC technology has become an important cornerstone of intelligent manufacturing. The innovation and breakthrough of numerical control technology has become an important guarantee for the completion of intelligent manufacturing engineering.
