Active vibration control with piezoelectric actuator on a lathe machine with a gain controller

In this study, an active vibration control on a CNC lathe machine by the use of a stack piezoelectric actuator is accomplished. In the implementation of piezoelectric actuators, dSpace 1104 Control Card is used as the control unit. By using the acceleration feedback signals measured on the cutting tool, the control signal being out-of-phase with the acceleration measurements is applied to the piezo electric actuators. The system is implemented on a Mazak CNC lathe machine. The experimental results show that the implemented active control approach yields reduction on surface roughness of machined parts.
