Frame design and reality of on-line quality control system for CNC machining center based on microcomputer

After giving a short review of the methods used for detecting and monitoring in general systems, this paper describes the way of communication between computer and Computer Numerical Control (CNC) Machining Center (MC). Based on these, the paper addresses the means of performing in-cycle measurement for manufacturing quality, provides an approach of improving the state of manufacturing process by achieving the real-time change of control parameters according to the level of manufacturing process, and discusses the technique of implementing in-process dimensional errors compensation corresponding to the in-cycle measurement. The results of the experiments show that the frame design is successful and the operation is reliable. The system is taking shape nowadays.
