| 摘 要： | 建立了平面应变有限元模型，采用更新的Lagrange方法模拟了奥氏体不锈钢AISI316L的正交切削过程；研究了刀刃圆弧半径对已加工表面残余应力的影响，发现随着半径的增大，残余拉应力和压应力的数值都增大，压应力层厚度也增大，但是拉应力层厚度不变。将模拟结果与实验结果进行对比，发现二者是吻合的，从而验证了有限元模拟的可用性。

| Abstract: | A plane strain finite element model is presented to simulate the effects of cutting-edge radius on residual stresses when orthogonal cutting austenitic stainless steel AISI 316L. Larger edge radius induced higher residual stresses in both the tensile and compressive regions, while it had almost no effects on the thickness of tensile layer and pushed the maximum compressive stresses deeper into the workpiece. The same trend was found experimentally, which validates the FE model. |
