Chatter suppression in turning operations with a tuned vibration absorber

In this paper, a piezoelectric inertia actuator is mounted on the cutting tool and acted as a tuned vibration absorber for the suppression of chatter in turning operations. It is shown that the tuned vibration absorber can modify the frequency response function of the cutting tool so as to improve cutting stability in turning operations. Chatter can then be effectively suppressed due to the increase of cutting stability. Theoretical studies and experimental results performed in turning operations are presented to illustrate this approach. (C) 2000 Published by Elsevier Science S.A.
