Paper Abstract

A measurement system to monitor the turning tool achieves a reduction in production rejects by decreasing the delay time between tool wear detection and quality control of the surface, which usually takes place after the time-intensive polishing process. In highly automated production of lucent synthetic lenses the standardized polishing process turns out to be inefficient if there is an insufficient surface quality caused by outrunning tool wear limits of the undergone turning process. The possibility to indicate the tool’s wear will be demonstrated by checking the surface characteristics of synthetic lenses. For that research an experimental measurement setup is shown. This optical measurement system detects the surface’s roughness, which is indicative of tool wear.
