Abstract: According to the requirement of new type NC computer cutting machine, this paper analyses the particularity of NC computer cutting machine control and then builds an open-architecture CNC soft system which is based on industrial PC. Besides the use of GD104 motion control card which is the core of the NC computer cutting machine control system, this article also presents the techniques of several main parts. Based on above hardware system, a Windows -based software system is developed. With the utilizing of object-oriented method, afriendly human machine interface and an efficient multithreading working environment is fulfilled.
Key words：NC cutter; GD104; open-architecture CNC system.
