Abstract：

The hardware and software structure of a CNC system for high feed rate punching ma- chine is introduced.A master- slave mode CPU is adopted in the CNC system.A high voltage copping constant currentdriving and low voltage locking circuitis designed.According to stepmotor property the accelerating and dropping time is limited to the smallest range,the high feed rate can be obtained.Ac- cording to punching property user′s instrutions are set based on ISO.User′s instructions are few and have a high function so the user′s programme can be decreased greatly.
