A Novel Embedded Numerical Control System Based on Resources Sharing

New requirements for current network numerical control (NC) were discussed. The authors put forward a new kind of embedded NC system based on resources sharing. In this system, embedded controllers connected by field buses composed the basic NC unit. These units connected to an embedded NC service system providing abundant functions and higher processing abilities through networks to acquire the integrated function in NC processing. Remote NC operating and monitoring can be achieved by remote control terminals connected to the embedded NC service system. Also the system can connect to the enterprise or global manufacturing networks to become one of the online processing units. Then, the paper introduced both the hardware and software of each module of the system in detail. Both the three-dimensional scrolling display effect of the processing trace and the solid figure display effect of the processing work piece acquired at the remote control terminal were shown at last. The results indicate that the system can perform well in the network numerical manufacturing environment.
