摘要

针对当前非圆齿轮插齿加工效率低、切削力波动大的问题，在对插齿切削力建模，建立切削力与切削面积的关系的基础上，提出了一种基于恒定切削力约束的圆周进给量优化方法。以提高工件的加工效率并减少切削力的波动为优化目标，以机床参数和恒定的切削面积为约束，并以节曲线曲率半径为分段依据，建立了变圆周进给量优化模型。通过3阶椭圆齿轮插削实例分析，验证了变圆周进给优化模型的有效性；采用分段优化，避免了各运动轴速度的频繁剧烈变化，实现了非圆齿轮插齿加工工艺参数优化。

Abstract

Aiming at current problems of low gear shaping efficiency and large cutting force fluctuations in non-circular gears，and based on the gear shaping cutting force modeling and the relationship established between the cutting force and the cutting area，the article proposes circular feed rate optimization method based on constant cutting force constraint. To improve the processing efficiency of the workpiece and reduce the fluctuation of the cutting force，with the machine parameters and the constant cutting area as the constraints，and taking the curvature radius of the pitch curve as the segmented basis，an optimization model of variable circumferential feed is established. Through the analysis of the third-order elliptic gear slotting example，the effectiveness of the variable circle feed optimization model is verified. The segmented optimization avoids frequent and severe changes in the speed of each axis of motion，and realizes the optimization of the processing parameters of non-circular gears.
