Research on Optimization of Non-circular Gear Shaping Technology based on Constant Cutting Force Constraint
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.
