VIBRATION ATTENUATION OF BORING BARS WITH NONLINEAR CONTROL FORCE

Abstract

An active method for boring bar vibration attenuation and chatter suppression is presented through the introduction of a nonlinear control force within a tuned mass damper. Its effects on process stability and its control options are discussed in detail. The effectiveness of the active damping system and the optimal control parameters are determined through numerical simulations carried out on a simplified linearized mechatronic model of the coupled nonlinear manufacturing system.
