Aiming at the development of new information technology and the application requirements of intelligent manufacturing in the aerospace industry

the multi-dimensional framework of the open and smart CNC system was established by analyzing the technical trends of the CNC system. Then a reconfigurable CNC system platform

a process chain integration based on an information terminal and a product life cycle management system based on industrial big data was proposed. Finally

the Lantian CNC system was developed

and the implementation routine of the open and smart CNC system was explored through the application and practice of the processing and control of typical parts in aeronautical engineering.
