摘　　要：运用大型通用有限元分析软件ABAQUS对金属切削加工过程进行非线性弹塑性有限元分析,讨论了切削模拟过程中切削力、应力场、应变的变化情况,验证了通过剪切失效和单元删除模型实现切屑分离符合切削理论。The metal cutting process is analyzed with elastic - plastic nonlinear element method based on ABAQUS. The cutting force, stress field and strain are discussed. By using shear failure and element deletion model, it＇ s suitable for cutting principles to realize chip material separates with workpiece material.
