摘　　要：汽轮机静叶片汽道出汽边加工变形是影响加工质量的关键。分析汽轮机静叶片加工过程中出汽边薄壁部分变形,结合静叶片出汽边的加工工艺,研究球头铣刀在出汽边铣削中的几何加工特征,构建其铣削力模型。在MATLAB环境下,对铣削力模型进行模拟仿真,选取不同的切削参数,得出了切削参数对叶片铣削力变化的曲线图,为后续的切削参数优化提供了理论依据。Deformation of exit edge is the key that effects the quality of turbine stationary blade.Combining with the processing technology of exit edge in turbine blade profile,geometry processing characteristics of ball-end milling was analyzed in the exit edge milling of turbine blade processing,and the milling force model was built up.In MATLAB environment,milling force model was simulated.Different cutting parameters were selected to analyze milling force.It provides theory basis for the follow-up cutting parameter optimization.
