| 摘 要： | 根据金属塑性变形理论，提出了在低速正交金属切削中工件表面层加工硬化深度的预报准则。讨论了切削变形区内的弹塑性应力场，建立了剪切平面边界载荷的分布方程，并通过有限元法模拟已加工表面的形成过程，计算了工件表面层的应力和硬化深度。数值分析与试验研究相一致。

| Abstract: | introduces a criterion for predicting the surface work-hardening depth in low speed orthogonal cutting, which is based on the theory of metal plastic formation.The elastic-plastic stress field in deformation zone is analyzed.The equations of boundary load on the shear plane are formulated.The relative stress and work-hardening depth in surface are calculated by simulating machined surface formation process. The numerical analysis is verified experimentally. |
