Abstract: An open CNC system with double cpu was proposed, in which an open motion-controlling processor was used as the subordinate computer and a PC-based platform was used as the principal computer running on the Microsoft Windows 9X/NT.In the open soft designing, the packaging and inheritance technique of classes was adopted, and the communication technique based on the server and client model was utilized between different function modules or between the function modules and the system kernel. The rotation buffer technique can perform the downloading of data files with any size from principal computer to subordinate computer. When the CNC system was applied to practical projects, the openness and practical value were verified.

Key words: open architecture, CNC system, serve/client, rotating buffer
