Research and development of CNC technology experimental bench based on PMAC

The CNC technology, which directly decides the function and pefformance of manufacturing equipments, is the key technique group that supports the modem equipment manufacturing industry. And it is also the key technique for equipment layer which can push forward industrialization with informatization. Through the research of open CNC, a kind of CNC system had been constructed based on IPC and PMAC motion control card. Further, studied the open CNC architecture and its constructing method. The designing method of modularization was adopted during the constructing of CNC based on PMAC motion control card, and the CNC was applied into NC technology experimental bench. The function and performance of CNC based on PMAC motion control card had been studied through experiments.
