A novel chatter suppression method in boring operation is proposed. The anisotropic boring tool with a step portion and notches on the cylinder periphery is designed, which has anisotropic dynamic characteristics. Since the direct and the cross transfer function components of the proposed tool are designed to cancel out each vibration, the nominal compliance of the boring tool in cutting process can be reduced significantly. Hammering tests of the developed tool clarified that appropriate anisotropic frequency response function is roughly attained by the proposed design. The developed tool was subsequently applied to turning experiments, and it was clarified that the stability limit in the radial depth of cut significantly increases by using the proposed boring tool as compared to the ordinary boring tool.

提出了一种新的镗孔加工中颤振抑制方法。设计了圆柱外周带有台阶部和缺口的各向异性镗刀，具有各向异性动态特性。由于所提出的刀具的直接和交叉传递函数组件被设计为抵消每次振动，因此可以显着降低镗削刀具在切削过程中的名义柔量。所开发工具的锤击测试表明，所提出的设计大致获得了适当的各向异性频率响应函数。随后将开发的刀具应用于车削实验，结果表明，与普通镗刀相比，使用所提出的镗刀，径向切削深度的稳定性极限显着增加。
