摘　　要：选取轴向切深、每齿进给量、径向切深和主轴转速为试验因素,采用YDX-Ⅲ9702型压电式铣削测力仪,进行了动态铣削力正交实验。针对立铣刀侧铣加工,研究了单刃铣削的临界条件,为设计试验方案提供了理论依据。结合铣削过程,采用角度积分方法求解铣削力模型,避免了轴向积分的繁琐计算。精确地建立了简捷且适应性强的基于切削层形状的动态铣削力预测模型,模型的仿真结果和试验数据相吻合。The orthogonal experiment of dynamic milling force was done by using the piezoelectric measurement in- strument of milling force of YDX-m9702 TYPE, while the axial cutting depth , the per tooth feeding, the radial cutting depth and the spindle rotation were selected as experiment factors. Aiming at side mill- ing process with an end mill, this paper studied on the milling critical condition when the single tool edge was used, and this provided a theoretical basis for the experimental design. Considering the milling process, angle integration limits were used to calculate the milling force to avoid trivial calculating when axial integration limits were used. A simple and adaptable prediction model of dynamic milling force was established accurately based on shape of cutting thickness, while the simulation results using the model and the experimental data are identical with each other.
