提高刀具系统刚度的切削振动消减措施

Vibration Absorbing Measures by Improving Cutting Tool System Stiffness

通过切削振动物理模型,分析了刀具产生切削振动的原因以及降低切削力、抑制刀具振动的方法。刀具系统静态和动态刚度对大悬径比深孔和型腔加工切削振动影响较大,重点介绍了提高刀具系统刚度的削振措施。

This paper uses the physical models in cutting vibration to analyze the cause of cutting vibration and discusses the restraining methods of controlling the cutting force. Cutting tool system＇ s static and dynamic stiffness seriously affects the vibration of deep hole and the cavity cutting. It lays special stress on introducing the vibration absorbing measures by improving the stiffness of cutting tool system.
