Abstract

The goal of this work is to allow a precise measurement of bar turning pieces. The dimensions of the pieces under study were smaller than 50mm. We have developed an illumination system which is specifically designed for a telecentric objective. Furthermore a special positioning system, which allows an integration of the measurement in a fabrication process, was added to the system. Thanks to this arrangement, it is possible to follow and master the fabrication process with a relative tolerance of the dimension of about 0.07 percent for the process and about 0.014 percent for the final control.
