| 摘 要： | 连续攻丝过程中的切屑堵塞造成攻丝扭矩增大和波动,很容易导致丝锥折断。本文分析了低频扭转振动攻丝促进排屑的机理,并通过实验分析了工艺参数对断屑效果的影响,证明回退量是影响切屑长短的主要因素。

| Abstract: | The tap is prone to be broken off because of the increase and undulation tapping torque caused by the blocking of chips. The mechanism of chip removal of low-frequency torsional vibration tap was analyzed. And the effect of machining parameters on the chip breaking was studied by experiments. It is indicated that the reverse rotation angle of tap is the main factor that influences the size of chips. |
