Research on Intelligent CNC Platform Based on Hierarchical and Distributed Architecture for Grinding Machine

摘要

Grinding is a complex process and grinding automation based on CNC technology is developing forward flexibility, intelligence and integration. A CNC system for grinding machine is gradually becoming a complex controlling platform with all kinds of advanced functional units and interfaces. The trend of unlimitedly increasing functional modules and peripheral interfaces causes two unfavorable results. One is that more and more system resources are occupied, which weakens the ability of CNC system in real-time task controlling and rapid events responding. The other one is that the whole system is gradually falling into some chaotic and unstable expanding status. So it is necessary to add reasonable decentralization tactics to the architecture of integrated CNC system for a balance status of necessary functions and optimized performance. This paper aims at the establishment of an intelligent CNC platform for grinding machine, and brings forward the conceptions of hierarchical platform, decentralized control, sharable resources and disassembling tasks to realize the simultaneous satisfactions of completed functions, reliable performance and simple interactivity of an intelligent CNC system platform for grinding machine.
