An active vibration control system for a turning process is presented. The system employs a magnetostrictive actuator and a rate feedback control scheme to suppress the vibration caused by random excitation in the turning process. A specially designed tool holder is developed to implement the actuation and the control scheme effectively. A model which accounts for both the dynamic response of the cutting process and the control system is described. The effectiveness of the vibration control system is studied via simulation and a series of experiments. A disturbance force is applied to the system by a shaker and the dynamic response of the system is observed. The experimental data shows that the rate feedback control scheme adds additional damping to the system and reduces the vibration. A complete set of 24 factorial design cutting experiments were also conducted using the tool holder and experimentally obtained surface profiles were compared to surface profiles obtained without the vibration control. It is shown that the system can improve the surface texture generated by the turning process.
