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.

In this paper the functional requirements of a B-ISDN access network based on MAN are investigated. Firstly, criteria of designing access network for the B-ISDN is studied. Secondly, the types of subscribers and their service requirements are defined. Thirdly, various architectures of CPNs(Customer Premises Networks) are considered and their characteristics are studied, Finally, the interworking functions of a DQDB MAN as an access network are investigated.
