Abstract

It is the mainstream that numerical control system is open and constituted based on PC and WINDOWS operation systems. This article summarily presents the function of numerical control technology; the merit of Opened System Architecture for Numerical Control, On the basis of which it discusses the research and development of open CNC system software based on Windows2000 operation system. Especially, it presents the design of the main interface of the CNC system、software module to control motion control card and communication software module between PC and Frequency Changer ,which controls the motor of main shaft. In additional, it provides the source codes. We are debugging the CNC system now, and we have got the expected machining precision.
