摘　　要：铣削力是导致铣削加工件变形及刀具磨损的主要原因,利用有限元软件进行铣削加工模拟仿真是预测切削力变化的重要方法;而任何金属切削仿真软件分析结果都会有一定的局限性,并不能完全的模拟实际加工过程.以铝合金高速铣削加工为研究对象,设计了其铣削方案,借助某经验公式计算并估计主切削力大小,并利用Deform 3D铣削仿真模块进行模拟加工得到铣削力数据,最后通过实际铣削试验验证仿真所得数据的可靠性,为仿真试验结果准确性提供依据.The milling force is main cause of parts deformation and tool wear in the milling process. Using the fmite element software for milling simulation is an important method to predict change of the cutting force. But every metal cutting simulation software has certain limitations, and can＇t completely simulate ac- tual machining process. This paper takes high-speed milling of aluminum alloy as the study object, and de- signs the milling scheme. The size of main cutting force is calculated and estimated with the aid of an em- pirical formula.By using the Deform 3D milling simulation module to simulate the machining process, the milling force data are obtained. Finally, the actual milling test verifies the reliability of the data from simu- lation, which provides the basis for the accuracy of the simulation results.
