This paper mainly studies the scheme and key technologies of PC-based open CNC system function. It analyzes the application status of open CNC system and expounds the structure of PC numerical control system and the structure of open CNC system. The paper designs low-cost, reconfigurable open CNC system and establishes open software and hardware components of the system. The system controller completes the planning process of input and output by programming, and controls the output of servo motor through PID. The optimized control target of the servo motor trajectory output realizes the development of the interactive control mechanism. The modular reconfigurable system significantly improves the performance of the system and reduces the system cost. It has high practical application value.
