硬质合金可转位车刀刀片的力学特性分析

为了深入研究切削过程中可转位刀具的力学特性，以硬质合金可转位车刀刀片为例，采用三维有限元方法对金属的切削加工过程进行模拟计算。考虑实际刀片几何形状及其安装角度，基于三维建模软件SolidWorks，建立了硬质合金可转位刀片三维立体模型；通过切削力试验测得切削力，利用内嵌于SolidWorks之上的COSMOS＼works对该刀片加载求解，进行应力场分析。结果表明，利用有限元方法对硬质合金可转位刀片分析的结论与其实际加工状况较为相符，为可转位刀片的优化设计提供了一定的方法和依据。

Analysis of Mechanical Characteristics of a Turning Carbide Insert

To take an example of a turning carbide insert, a 3D finite element method was employed to simulate the cutting process of the carbide insert, investigating its mechanical characteristics. In detail, based on the real shape and the mounting angles of the insert, a 3D prototyping model was firstly generated using SolidWorks. And then the cutting forces from the experiments were loaded on the insert to implement FEA on it with COSMOS\works, which adds in SolidWorks. Generally, the results from the finite elem...
