摘要：利用ABAQUS对钛合金材料铣削过程进行有限元分析，得到铣削力数据。在相同工艺参数条件下进行钛合金铣削试验，通过仿真切削力与试验测得切削力对比，验证了有限元模型的准确性。以每齿进给量为单因素变量，得到了不同每齿进给量下的铣削力，为钛合金铣削加工中工艺参数的选择提供参考。

Abstract:The finite element analysis of milling process of titanium alloy material is carried out by ABAQUS，and the milling force data is obtained.Then the milling force test is carried out under the same parameter condition，and the reliability of the FEM model is verified by comparing the simulated milling force with the measured milling force.The milling forces are obtained by taking the feed peer tooth as a single factor variable，providing a reference for the selection of process parameters in titanium alloy milling process.
