Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods and machines are inadequate for efficiently processing hard-coated brake disks due to the high forces required, which leads to ineffective surface processing and potential contamination issues.
Innovation Solution
A method and device that involve angulating the grinding wheel axis of rotation relative to the workpiece axis of rotation, allowing the grinding wheel to make contact with the workpiece surface at a smaller area, thereby increasing pressure and improving ablation of the hard-coated surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional grinding methods with parallel axes are used on hard-coated brake disks, then the contact area between grinding wheel and workpiece is large, but the processing effectiveness is insufficient due to high required forces
Solution Approach 1:
The patent applies asymmetry by angulating the grinding wheel axis relative to the workpiece axis, creating an asymmetric contact geometry. This angulation transforms the symmetric parallel-axis contact into an asymmetric configuration where the contact area is reduced while maintaining effective processing of the hard-coated surface, thereby reducing required processing forces while improving productivity
2Stress or pressure
If the grinding wheel axis is angulated to the workpiece axis, then the contact area is reduced and pressure is increased, but the device complexity increases due to additional angulating mechanisms
Solution Approach 1:
The patent implements dynamics by making the grinding wheel axis angulation adjustable rather than fixed. The angulating device allows the grinding wheel axis to be dynamically positioned at different angles relative to the workpiece axis, enabling optimization of contact pressure for different hard-coating conditions while maintaining operational flexibility and reducing the need for multiple fixed-angle devices
