Abstract :
Because servo loop controller is very important in CNC milling machine, fast processing unit is necessary for high speed multi-axes CNC controlling. This article introduces how to control this High-Speed CNC milling machine by using Field programmable Gate Array (FPGA). Due to FPGA structure that can process concurrently, it can simultaneously control several axes movement. Therefore, servo loop time is constant even more axes are controlled. PID-Feedforward controller with Anti windup is applied in this development for High-Speed CNC controlling with FPGA.
