Vibration drilling possess the special function of reducing chatter vibration, 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。

Even if the date of back cutting depth is bigger in the parts of cutting velocity, the cutting system's chatter vibration 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。

Applying the concept of relative cutting velocity, the expression of velocity type dynamic cutting force and the mechanics model of chatter vibration in turning or boring process were advanced.

针对规避切削颤振问题，应用相对切削速度概念，提出了速度型动态切削力表达式以及车削或镗削的振动力学模型。
