Vibration drilling possess the special function of reducing chattervibration, thus achieving a good drilling effects.
振动钻削方法具有消减切削颤振的特殊功能，能够取得良好的加工效果。
2
Even if the date of back cutting depth is bigger in the parts of cutting velocity, the cutting system's chattervibration might not be happened.
如果公称切削速度处于该稳定区域，即使背吃刀量较大，系统也不易发生颤振。
3
Applying the concept of relative cutting velocity, the expression of velocity type dynamic cutting force and the mechanics model of chattervibration in turning or boring process were advanced.
