Abstract Process damping is useful in improving chatter stability in a low cutting speed range. This paper presents a texture design on tool flank faces that can effectively generate process damping. A convex structure on the flank face dampens chatter vibration even at general cutting speeds. An orthogonal cutting simulation utilizing a finite element analysis was conducted to estimate process damping force coefficients that are the functions of cutting and vibration conditions and tool geometry. Sufficient damping effect was predicted using the proposed texture via a chatter stability analysis in frequency domain. Face turning experiments verified the significant chatter suppression effect.

后刀面纹理设计，抑制切削时的颤振

摘要 过程阻尼有助于提高低切削速度范围内的颤振稳定性。本文提出了一种刀具侧面的纹理设计，可以有效地产生过程阻尼。即使在一般切削速度下，侧面的凸面结构也能抑制颤振。进行了利用有限元分析的正交切削模拟，以估计作为切削和振动条件以及刀具几何形状的函数的过程阻尼力系数。通过频域中的颤振稳定性分析，使用建议的纹理预测了足够的阻尼效果。转脸实验验证了显着的颤振抑制效果。
