Abstract
The authors investigate the dynamic behavior of a lathe chuck in view of suppressing the chatter vibration in the turning operation. The dynamic behavior is greatly affected by the damping and rigidity characteristics of the system. In this paper, a model chuck with an impact damper is produced through experimentation, and its behavior is investigated. This chuck is found to control the damping capacity under the condition of effective constant rigidity. The following conclusions are drawn. (1) The most appropriate damping characteristic for suppressing chatter vibration corresponds to the rate of vibration. (2) Some damping effects can also be recognized on the surface of workpiece under stable conditions.
