The mechanical design of ultra precision machine tools is very well experienced today. In contrast to that, the design and implementation of closed loop controls for high precision applications have not been sufficiently analyzed yet. In addition to that, enhancements to further increase the achievable form accuracy and surface quality and at the same time decrease cycle times and error sensitivity of precision processes can only be accomplished by enhancing the machine control. At the Fraunhofer IPT a test bench has been developed to analyze machine controls, servo drives as well as encoder and sensor systems with regard to an evaluation of capabilities of their application in ultra precision machines. First analyses have been accomplished focusing on the performance of servo drives, which will be presented in this paper.
