Abstract：Multi-tool intermittent cutting way of thread whirling will increase interactive impact between the whirling cutter head and the workpiece, arouse the torsional vibration of the whirling cutter head system and reduce the processing quality. Aiming at the characteristic that the whirling head system has tensional vibration under periodical cutting moment, the silicone oil damper was applied to suppress vibration of whirling head. The dynamic model of the whirling head system based on the silicone oil damper was set up, and then the dynamic response of the system with and without silicon oil damper was investigated based on the amplitude-frequency characteristic of the model, so as to analyze the vibration suppressed effect of the damper for the whirling head system. The result shows that the silicon oil damper can effectively reduce the vibration amplitude of the whirling head system under different cutting frequency. When the system resonance occurs, the tensional vibration response amplitude of the whirling head system is decreased to 7.10×10-4rad, which is helpful to improve the workpiece quality and tool life.
