Abstract

In-process shape measurements of rotating objects such as turning parts at a metal working lathe are of great importance for monitoring production processes or to enable zero-error production. Therefore, contactless and compact sensors with high temporal resolution as well as high precision are necessary. Furthermore, robust sensors are required which withstand the rough ambient conditions in production environment. Thus, we developed a miniaturized and robust non-incremental fiber-optic distance sensor with dimensions of only 30x40x90 mm³ which can be attached directly adjacent to the turning tool bit of a metal working lathe and allows precise in-process 3D shape measurements of turning parts. In this contribution we present the results of in-process shape measurements during the turning process at a metal working lathe using a miniaturized interferometric distance sensor. The absolute radius of the turning workpiece can be determined with micron precision. To proof the accuracy of the measurement results, comparative measurements with tactile sensors have to be performed.
