Notes:
Chatter during boring process is one of the main adverse factors influenced on themachining accuracy of precision hole, surface quality and working efficiency. In order to suppresschatter, an innovative controlling means of MR-intelligent-boring-bar with self-chatter-suppression isproposed, which is composed of MR fluid, shell structure, excitation coil and boring bar. The MRfluid’s mechanical characteristic can be adjusted by changing the intensity of magnetic field, thus thesystem stiffness and damping will be modified, and then the boring chatter can be suppressed.Otherwise, the dynamic model of MR-intelligent-boring-bar with self-chatter-suppression is built.Lastly, the experimental system of MR-intelligent-boring-bar is established, and the experiments ofchatter suppression during boring process are performed. The results of experiments show that thenew means of chatter suppression is effective
