Aiming at the chatter problem of milling thin-walled parts, a vibration suppression method based on additional mass and eddy current damping is proposed. Firstly, a dynamic model of milling machining of thin-walled parts is established, and the influence law of additional mass and eddy current damping on the machining stability region is obtained through flutter stability analysis; Then an optimization method for added mass of thin-walled parts is proposed to obtain the optimal added mass layout and mass proportion; Finally, a set of thin-walled parts processing vibration suppression device was designed, and the thin-walled parts milling experiment was carried out. The research results show that when the additional mass combination [15,10,15] and eddy current damping are added at the same time, the thinwalled workpiece machining vibration is significantly suppressed, which verifies the effectiveness of the proposed vibration suppression method.
