小孔的万向联轴器振动钻削机理

Study on the Principle of Drilling Small Hole bythe Power of Vibrating Universal Coupling

本文研究了特殊万向联轴器振动机构的发振机理。利用相位角为零的波形面切削，避开了钻头的冲击，并且由于切削时前角、后角等因素的变化，可以达到更好的钻孔效果。

fo this peper, it is Ptoched that special universal coupling mechanismProduces vibrating and using wave-shape surface cutting at zero degree of Phase-angle, shocks ofdrill edge are avoided.And with varying rake and clearance angles, better drilling result can beattained.
