Performance analysis of feed-drive systems in diamond turning by machining specified test samples

In the field of ultraprecision machining proper performance of feed drive systems is necessary. Smallest depths of cut, smooth surfaces and minimal shape errors of complex parts are required. To test the behavior of high precision feed drive systems several direct and indirect analysis methods can be applied. In this report three indirect test methods are presented. By machining and evaluation of specified workpiece samples information about the feed drive behaviour are obtained. Correlations between surface-shape, surface-describing parameters and the position data of the cutting tool are made. The work is to be considered as a contribution to the testing of ultraprecision machine tools.
