摘　　要：滚齿是重要的齿轮加工工艺之一,其加工成形过程复杂,并且涉及较多切削参数。为了量化切削参数对滚切力的影响,研究了一种基于三维几何仿真的滚齿切削力预测方法。根据滚刀和工件的几何参数以及切削参数确定加工过程中滚刀和工件的相对位置和运动关系,在CAD环境中实现滚齿运动过程的三维仿真,并得到未变形切屑的三维模型;根据选定的切削力模型,利用未变形切屑模型的截面尺寸计算单个切削刃的瞬时切削力,得到滚齿的整体受力过程;定量分析了不同切削参数对滚齿切削力的影响。该预测模型有助于滚齿加工工艺过程的优化设计,以提升加工质量和效率,降低加工成本。Hobbing is one of the most important gear machining process,forming process of which is complicated and involves a large number of cutting parameters. In order to quantify the influence of machining parameters on the cutting force in hobbing process,a method for predicting the cutting force of gear hobbing based on three-dimensional(3 D)geometric simulation is studied. The relative position and motion relationship between hob and workpiece are determined according to the geometric parameters and cutting parameters of hob and workpiece,the 3 D simulation of hobbing process is realized in CAD environment,and the 3 D model of undeformed chips is obtained. According to the selected cutting force model,the instantaneous cutting force of a single cutting edge is calculated by using the cross-section size of undeformed chips model,and the overall cutting force process of hobbing is obtained. The influence of different cutting parameter on hobbing cutting force is analyzed quantitatively. The predictive model helps to optimize the design of the gear hobbing process to improve the quality and efficiency of the machining and reduce the cost.
