Gear Cogging Control for Tooth Thickness and Flank Line Shape
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current rolling machining methods lack the flexibility to independently control tooth thickness and edge line form on both sides of a gear, leading to suboptimal tooth geometry and material removal during gear processing.
Innovation Solution
The method involves adjusting the axis distance and axis inclination angle of the tool relative to the workpiece, allowing for independent control of tooth thickness and edge line form on both sides by modifying the rolling coupling, which can be achieved through targeted adjustments of the axis distance, axis inclination angle, and rolling coupling correction based on the workpiece width position.

1Manufacturing precision
If separate material removal settings are applied on right and left flanks, then the gear geometry quality is improved, but the processing complexity is worsened
Solution Approach 1:
The patent implements dynamic control of the axis inclination angle during the machining process, allowing real-time adjustment of material removal rates on different flanks. This dynamic adjustment enables separate material removal settings for right and left flanks, improving gear geometry quality while the control system manages the processing complexity.

AI summary
The present invention relates to a method for gear machining of a workpiece by a tool on a gear cutting machine, wherein the workpiece is machined by a gear-cutting process in which the gear-cutting tool rolls on the workpiece with a predetermined center distance and axis cross angle, wherein the gear machining is preferably carried out on two flanks, wherein a desired flank line shape and/or tooth thickness of the gear is produced by the gear-cutting process, wherein an additional condition can be specified and the center distance and the axis cross angle are determined as a function of the desired flank line shape and/or tooth thickness of the gear and the additional condition.
