Abstract：With the analysis of history and status of the numerical control system, the signs of different development stages are summarized focusing on composition structure, driving characteristics, process methods and functions. With the influence of PC and open architecture, numerical control system reaches a stage in which all flowers bloom together. Digitization, networking and intelligence have become the consensus for the development of intelligent manufacturing. CNC system has been on the road of digitization since its birth. Fieldbus, real-time Ethernet and industrial internet technologies not only enable the CNC system itself, but also realize network interconnection with the outside world. Based on the analysis of the demand of intelligent CNC machine tools, the technical routes and implementation cases of intelligent CNC systems at home and abroad are analyzed, and the key technologies and prospects for the development of intelligent CNC systems are given
