以刃倾角大于４５°的斜角切削为基础，通过获取切屑根部标本，分析了大刃倾角切削的切屑外形和金相显微组织的变形情况，给出了刃倾角与变形系数和剪应变之间的关系曲线。
Based on the bevel cutting with the cutting edge inclination greater than 45 °, the chip shape and the deformation of the microstructure were analyzed by taking the root samples of the cutting edge. The relationship between the cutting edge angle and the deformation coefficient and the shear strain Relationship lines.
