Integrated Passive and Active Vibration Control of Ultra-precision Lathe

In ultra-precision cutting process, vibration is one of the key factors affecting the machining quality. In this paper, the damping methods of HCM-I Ultra-precision Lathe are discussed in both complete machine and slide. It is pointed out that integrated passive and active vibration control (IPAVC) by combining passive vibration control (PVC) and active vibration control (AVC) can not only eliminate high frequency vibration but also improve the damping effect to low frequency vibration. Experiment results show the effectiveness of the integrated passive and active vibration control.
