Abstract

Turning-machining is an important manufacturing process, widely used in industry. The dynamic interaction between the tool and the workpiece may cause regenerative chatter, that is associated with poor surface finish, reduced product quality and low productivity. The demand for accuracy motivates
development of active vibration control methods based on realistic dynamic models of the turning process. This study investigates the performance of a novel active robust control law for chatter attenuation that is based on an extended dynamical model of the chatter regenerative process. The extended model describes an external turning process, and includes the influence of the workpiece elasticity and the actuator finite bandwidth.
