Design of the Micro-V-Groove Ultra-Precision CNC Electric Transmission Communication System

In this paper, an electric transmission communication system of micro-V-groove ultra-precision CNC machine with the Mitsubishi PLC is designed. Different from the traditional method using the RS232-BD board, which has to communicate with PLC by programming offline, the system we design connects PC and PLC more directly and is more suitable for micro-V-groove ultra-precision CNC machine tool because of its real time. Embed the communication system in the CNC system, all the external devices can be monitored real-timely and the machine has run successfully.
