Elimination of vibration in turning process by an active work-rest mechanism

摘要

The prupose of this research is to increase the efficiency and accuracy of the turning process by means of an active work-rest mechanism. An prototypical experimental mechanism which controls one degree-of-freedom motion of a workpiece is made and experimentally investigated. The mechanism supports the workpiece and controls its radial motion by means of a feedback system composed of a noncontact sensor, a linear actuator and a PID controller.
