In this study, an MES (Manufacturing Execution System )/ DNC(Distributed Numerical Control) system is design ed in which hybrid CNC machine tools are distributively controlled and man aged in realtime. The system is operated as a stand-alone system or integrated with higher systems (MRP, DC etc.) through specially designed protocol. For support in g CNC controller s and operator s in hard realtime multi- tasking, we developed IMCP (Intelligent Multi - Communication Processor) and MMI (Man Machine Interface) unit. It allows the machine shop to be paperlessly operated under a synchronous control of information.

Cutting tool life monitoring is a critical element needed for designing unmanned machining systems. This paper describes a tool wear measurement system using computer vision which repeatedly measures flank and crater wear of a single point cutting tool. This direct tool wear measurement method is based on an interactive procedure utilizing a image processor and multi-vision sensors. A measurement software calcultes 7 parameters to characterize flank and crater wear. Performance test revealed that the computer vision technique provides precise, absolute tool-wear quantification and reduces human maesurement errors.
