摘　　要：针对在实际生产中选择和优化设计刀片刃口参数的难题,采用了多种有限元模型对不同刀片刀尖圆弧半径的直角切削试验进行仿真。通过有限元仿真得到的刀片主切削力和刀片温度场分布都吻合于实际的切削情况,为以后的刀片刀尖圆弧半径的选择和优化设计提供了一种有效的解决方案。The aim of this study is to compare various simulation models of orthogonal cutting process with different cutting comer radii. Some commercial finite element codes has been used. Estimated cutting forces and temperature distributions match well with the practice. As a result,it has been found that FEM can be used for selection and optimization of tool cutting corner radius.
