Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If chamfering is performed with a fixed tool profile, then the tool structure is simple, but the manufacturing precision of the chamfer shape is poor and cannot achieve predetermined parameters
Solution Approach 1:
The patent applies dynamics by making the tool profile alterable rather than fixed. The chamfering tool is equipped with a profiling mechanism that can dynamically adjust the cutting edge geometry during machining operations, allowing the tool to adapt its profile to achieve predetermined chamfer parameters while maintaining operational flexibility
Solution Approach 2:
The patent implements parameter changes by enabling modification of the tool profile parameters through the profiling system. The cutting edge geometry can be altered to match specific chamfer requirements, transforming the tool from a fixed-profile instrument to a variable-profile system that achieves precise manufacturing parameters
2Manufacturing precision
If chamfering is performed with a geometrically undefined cutting edge, then the surface quality is higher, but the tool cannot meet full machining time requirements
Solution Approach 1:
The patent ensures continuity of useful action by coordinating the tool profiling with the axial machine control system. This coordination allows the geometrically undefined cutting edge to continuously produce high-quality surfaces while the synchronized control maintains optimal machining speeds, preventing productivity loss
Solution Approach 2:
The patent implements feedback through the coordinated action between profiling and axial machine control. The system monitors and adjusts the profiling process in real-time based on machining conditions, ensuring that surface quality requirements are met while maintaining efficient machining rates
3Manufacturing precision
If separate tools are used for different chamfer parameters, then the manufacturing precision is high, but the device complexity and tool changes increase
Solution Approach 1:
The patent applies universality by designing a single chamfering tool with multi-functionality. The tool can be reprofiled to accommodate different chamfer parameters through the profiling mechanism, eliminating the need for multiple specialized tools and reducing tool system complexity while maintaining precision
Solution Approach 2:
The patent uses dynamics to enable the single tool to adapt its profile for different chamfer requirements. The alterable profiling system allows the tool to dynamically change its cutting edge geometry, providing the flexibility of multiple tools within a single tool structure
4Adaptability or versatility
If material is removed with a geometrically undefined cutting edge through coordinated profiling, then the adaptability to varying workpiece batches is high, but the device complexity increases
Solution Approach 1:
The patent implements parameter changes through the profiling system that can adjust the cutting edge geometry based on workpiece batch requirements. This allows the tool to adapt to varying chamfer parameters for different workpiece batches while the coordinated control system manages the profiling adjustments

AI summary
The invention relates to a method for producing a removal of material on a tooth end edge of a workpiece toothing with a rotationally driven chamfering tool in a machining operation brought about by controlled axial machine movements between the chamfering tool and the likewise rotationally driven workpiece toothing, wherein material is removed with a geometrically undefined cutting edge and the removal takes place in a coordinated action between a profiling, in particular, an alterable profiling, of the chamfering tool and a machine control used for the machining operation, performed in dependence on predetermined parameters that are characteristic of the removal of material to be produced.
