Abstract: A modular, reconfigurable, interoperable, scalable CNC controller architecture is proposed and implemented that provided a way for rapid customization and development of a new CNC controller by combining the advantages from the PC, RT-Linux and real time component. After reviewing the real time performance of the component available, such as CORBA, COM/DCOM, the component that can be used to the real time control is presented. The components and their interfaces of a base CNC controller are given, and the controllers’ architecture is presented. A virtual module system that is used to communicate and schedule the components is put forward. The configuration system is realized by using the key techniques such as configuration file and software synthesis. Finally the system prototype was implemented on the RT-Linux.
