Multi-sensor intelligent system for on-line and real-time monitoring tool cutting state in FMS

The principle and the constitution of an intelligent system for on-line and real-time monitoring tool cutting state were discussed and a synthetic sensors schedule combined a new type fluid acoustic emission sensor (AE) with motor current sensor was presented. The parallel communication between control system of machine tools, the monitoring intelligent system, and several decision-making systems for identifying tool cutting state was established. It can automatically select the sensor way, monitoring mode and identifying method in machining processing so as to build a successful and effective intelligent system for on-line and real-time monitoring cutting tool states in FMS.
