With the development of computer and network technology and the application of machine tool, in order to resolve the
traditional stand-alone mode, enhancing the efficiency of NC (numerical control) system. Through introduce CAN
(Controller Area Network) bus, a new type of LAN (Local Area Network) was designed. The network system structure
and the embedded NC system based on ARM9 and motor control chip MCX314As were given. This LAN embedded NC
system can realize one computer control more NC tool and resolve the problem of low real-time which result from
network transmission. The realization of whole system can improve efficiency of NC processing and enhance real-time
ability.
