abstract = "An adaptive vibration control technique for improving surface finish is explored. In some cases, additional processing to improve surface finish quality after machining, such as grinding or polishing, is either not feasible or is not cost-effective. The focus of this research is on the development of an improved turning processes through the use of active vibration damping. Demonstration of the tool holder shows reduced relative tool-workpiece vibration and improved surface finish. The toolholder employs a high bandwidth piezoelectric actuator and collocated piezoelectric displacement sensor, with an adaptive positive position feedback control algorithm for vibration control and chatter reduction. The performance of this method is evaluated by comparing the surface finishes obtained with active vibration control versus baseline uncontrolled cuts. Surface finish roughness was measured using profilometry gages. Considerable improvement in surface finish and reduction in chatter amplitude are observed analyzed for applications in modern day machining.",
