Principles of an in-process monitoring system for precision grinding machine

Monitoring system is an economic and effective method for quality control in automatic manufacturing. The complexity of the grinding process asks higher requests on the monitoring system compared with conventional ones widely used in heavy industry. The paper is dedicated to monitoring techniques in precision grinding. Existing monitoring methods centering round single grinding process quantity are talked about. Multi-sensor fusion is the only way to improve monitoring reliability. Under the frame of the intelligence grinding system, a two-layer in-process monitoring system for precision grinding machine is brought forward to realize quality control, machine healthy maintenance, wheel life expiration judgment and parameters optimization.
