A reduction of 83% in surface roughness (Ra) was observed during the cutting process. The experimental results showed a significant suppression in chatter vibrations and improvement of surface roughness using the proposed active damper. A fixture was designed using special stiffeners such that it limited the tool displacements in the tangential and feed directions to only 0.2 µm and 0.4 µm, respectively, while allowing for movement in the radial direction in the actuator’s force direction. In this work, the radial strain signal as a result of radial chatter vibrations from the strain gauge is used as a feedback signal to the actuator using a feedback controller. The active damper consists of a piezoelectric actuator with an embedded strain gauge for measuring the vibration displacement. This paper presents a novel design and development of an active damper for chatter suppression of hard turning processes using a piezoelectric actuator and strain signal for chatter detection. One of the major factors affecting the surface roughness is chatter vibrations. A high roughness or poor profile accuracy results in higher friction and higher wear rate of the surface. Surface roughness and profile accuracy on rolling or sliding surfaces are critical for the wear and fatigue of a component.
