Gear Deburring Cutter Teeth Layout for Longer Tool Life
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tools for chip-removing deburring and chamfering of workpiece toothings face a conflict between low manufacturing costs and long tool service life, as they are either costly to produce or wear out quickly.
Innovation Solution
The tool features cutting edges formed by tool teeth arranged around the rotation axis, allowing for a large number of cutting edges to be created in a cost-effective manner, reducing individual edge stress and extending tool life.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If cutting edges are formed by separate cutting plates mounted on carrier elements, then manufacturing costs are reduced, but tool service life is shortened due to higher wear on each cutting edge
Solution Approach 1:
The tool is divided into multiple cutting edges formed by individual tool teeth of a tool toothing, where each tool tooth forms at least one cutting edge. This segmentation allows the wear to be distributed across multiple cutting edges, extending tool service life while maintaining cost-effective manufacturing through the modular tool toothing structure.
Solution Approach 2:
The cutting edges are arranged distributed around a tool rotation axis and extend along the rotation axis, transitioning from a single-plane arrangement to a three-dimensional distributed configuration. This spatial distribution increases the number of cutting edges without proportionally increasing manufacturing complexity, as the tool toothing structure naturally provides multiple cutting edges in different angular positions.
2Duration of action of stationary object
If a large number of cutting edges are provided, then individual cutting edges experience less stress and wear less quickly, but manufacturing complexity and cost increase
Solution Approach 1:
The tool toothing structure serves multiple functions: it provides the cutting edges for deburring and chamfering, defines the spatial distribution of cutting edges around the rotation axis, and establishes the extension of cutting edges along the rotation axis. This multi-functionality allows a large number of cutting edges to be achieved without proportionally increasing structural complexity.

AI summary
Described and illustrated is a tool for chip-removing deburring and/or chamfering of a workpiece toothing including a plurality of workpiece teeth, having a plurality of cutting edges for chip-removing deburring and/or chamfering of workpiece edges, in particular front edges, of the workpiece toothing each extending between a tooth flank and a front side of a workpiece tooth, the cutting edges arranged distributed around a tool rotation axis of the tool and each having an extension along the tool rotation axis. In order that the compromise between low manufacturing costs and long tool service life can be improved, it is provided that the cutting edges are formed by tool teeth of at least one tool toothing of the tool.
