Drive Based Vibration Reduction for Production Machines

Abstract

Machine vibrations constitute a persistent challenge for high performance and high precision production machines that show resonant behaviour at some frequencies. Most remedies require additional actuators or precise knowledge of the dynamic behaviour of the machines under consideration. To overcome this limitation, we present several techniques that use the feed drives to dampen vibrations or avoid excitation and are applicable with minimal pre-knowledge. Moreover, we introduce an approach to treat machines with resonant frequencies that change with the tool centre point position.
