Abstract

Up to now lots of CNC system used traditional DOS to realize real time control by hardware interrupt programming. To make computer numerical control system flexible and open can meet requirements of higher real-time. This paper used ARM9 processor S3C2410A with the RISC system of SAMSUNG Company, and realized precise interpolation of NC interpolation by the way of software on EVC platform with the aid of WinCE OS. Coupled with the motor drive module, it can achieve a simple NC function of four quadrant arc interpolation will be realized by programming used by point-by-point comparison method.
