Vibration control of a CNC lathe with a pipe structure frame by a PZT

摘要

The development of a small machine tool for the purpose of parts minimization has been approached through downsizing and increased precision. A new CNC lathe combining sufficient rigidity and space for chip treatment has been developed. The frame structure consists of pipes and joints, guaranteeing sufficient space. Active vibration control is applied in order to suppress the specific vibration mode using actuators driven by a PZT. The effects of vibration control are reported in the present paper.
