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.
