Chatter suppression in turning operations with a tuned vibration absorber

In this paper, a piezoelectric inertia actuator is mounted on the cutting t ool and acted as a tuned vibration absorber for the suppression of chatter in turning operations. It is shown that the tuned vibration absorber can mo dify the frequency response function of the cutting tool so as to improve c utting stability in turning operations. Chatter can then be effectively sup pressed due to the increase of cutting stability. Theoretical studies and e xperimental results performed in turning operations are presented to illust rate this approach. (C) 2000 Published by Elsevier Science S.A.
