Research and Development of Open-Architecture Computer Numerical Control System of Fast-Point (Grinding)-Machine

Open-architecture CNC(Computerized Numerical Control) system based on PC and Windows operating system is the trend of the CNC.The study of the fast point(grinding) forming machine is introduced in this paper.The GE-300-SG-PCI motion control card and a NC-embedded PC open-architecture CNC system are applied in the research.The design of the hardware structure and the software platform based on Windows operating system is accomplished.The motion control card and the communication between the motion control card and PC are introduced expecially for open-architecture CNC system of this fast point(grinding) forming machine.It is proved that the shorter the exploit period of this system is,the higher the degree of opening is,the better the motion control is,and it could be in common application.So this system has a good future of development and economic benefit.
