Abstract：Smart material is increasingly being used for vibration control systems due to its fast response, easy control and little energy consumption. In this paper, A damping device based on smart materials——electrorheological fluid (ERF) was developed to suppress the chatter in turning slender shaft. The theoretical analysis shows that the control voltage corresponding to the best damping effect is not the same under different cutting conditions. Thus, a fuzzy control system with ERF for turning chatter was developed, and semi-active fuzzy control experiments were carried on. The experimental results show that under different cutting conditions the fuzzy control systems can adjust the control voltage adaptively so that the acceleration response were reduced and the chatter was inhibited.
