摘　　要：刀具几何参数是金属切削加工过程中切屑的形成、切削力的大小以及散热条件等的重要影响因素,影响被加工工件的表面质量。针对汽轮机薄壁叶片的加工变形,采用ABAQUS对切削加工过程进行有限元模拟,对刀具的几何参数进行优化,运用优化后刀具进行汽轮机静叶片的铣削加工。实验结果表明,薄壁叶片加工过程中的变形得到有效改善。The geometrical parameters of cutter are important influencing factors of the formation of chip,the size of cutting force and the heat dissipation condition in metal cutting process,which have influence on the surface quality of the workpiece.To prevent the deformation occurring in machining the thin-walled turbine blades,ABAQUS is used with the finife element method to simulate the machining process,then,the geometrical parameters of the cutter are optimized.The optimized tool is used for the milling of the static turbine blades.The experimental results show that the machining quality of the thin-walled turbine blades is improved greatly.
