Solution Overview
Problem
The use of multi-edge tools in machining processes requires manual edge switching due to varying workpiece shapes, leading to increased cycle times and operational complexity.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual edge switching is performed in multi-edge tools, then operational control is maintained, but cycle time increases and operational complexity increases
Solution Approach 1:
The system enables automatic edge switching by having the numerical controller autonomously determine when edge switching is necessary based on workpiece shape characteristics and tool path analysis, eliminating the need for manual intervention while maintaining optimal machining conditions
Solution Approach 2:
The system pre-calculates edge switching paths and retract paths before actual machining operations begin, allowing the controller to prepare switching sequences in advance and execute them automatically without interrupting the machining flow
2Ease of operation
If manual edge switching is performed in multi-edge tools, then operational control is maintained, but program complexity increases
Solution Approach 1:
The numerical controller automatically generates and manages edge switching programs by analyzing the machining task commands and workpiece geometry, eliminating the need for operators to manually write complex switching programs while maintaining full operational control
Solution Approach 2:
The system replaces manual programming operations with automated computational algorithms that calculate optimal edge switching paths and sequences based on machining parameters and tool geometry
3Device complexity
If edge switching is performed without automatic path calculation, then simple control is maintained, but cutting load uniformity decreases
Solution Approach 1:
The system uses feedback from machining task commands and workpiece shape analysis to dynamically adjust edge switching timing and paths, ensuring that cutting loads remain uniform across different edges while maintaining automated control
