Realization of Wireless Communication between CNC Turret Punch Press

Through analyzing defects of the traditional open CNC system based on PC,a CNC turret punch press CNC system was proposed based on real time and multi task embedded operating system WinCE7 and CORTEXA8 microprocessor. WinCE7 operating system, a compact and efficient modular operating system, and CORTEXA8 microprocessor can meet the requirements of real time control of CNC turret punch press. The development trend of communication mode between computer and NC machine tools and the influence on the efficient automation of machine tools were analyzed. The wireless communication solution of CNC turret punch press was proposed based on the WiFi. The experimental results show that: WiFi module is working correctly, data transceiver between the host computer and the embedded controller can be realized, cost is reduced and efficiency is improved.
