Adaptive Vibration Control of Machining via PZT Actuator

Abstract

At present, the techniques developed to control machine tool vibration have been dominated by passive features, focusing on manipulating the cutting parameters such as feed rate, cutting speed, and depth of cut. Since productivity is affected when modifying cutting parameters, other control methods must be investigated. To that end, electroactive actuators and robust control algorithms have attributes that make them potentially effective in reducing the vibration level. In this paper, the successful use of an adaptive control with a piezoelectric actuator to decrease the vibrations in a machine tool is reported.
