Abstract
This paper proposed three types of milling cutter, including the normal one, the modified cutter with high damping alloy sleeve, the modified cutter with high damping sleeve and gasket, these three type of cutters are identified with type A, type B and type C respectively. The testing items including cutting force, surface smoothness and fatigue life of above three type of cutter are conducted under different working conditions respectively. The result shows that the milling cutter with high damping alloy behaves better and could improve the related performance dramatically. Specifically, the cutting force of the cutters including type B and C is lower obviously than type A at three different directions, and type C cutter has the lowest cutting force and has the best anti-vibration effects. Additionally, under working condition 1, the surface smoothness of the three type of cutters have the similar behavior. But under working condition 2, the high damping milling cutter has at least 30% improvement. Finally, at the aspect of the fatigue life, the milling cutter with high damping alloy has at least 54.55% better performance than the normal cutter, and the wear of the high damping cutter is at least 38.13% less than normal cutter.
