Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual core removal is performed between rough machining and finishing, then core removal can be completed, but continuous operation is disrupted and overall efficiency cannot be significantly improved
Solution Approach 1:
The system performs core removal automatically without human intervention. The control unit coordinates the wire electrical discharge machine to execute core removal operations based on stored machining programs, enabling the system to service itself during the manufacturing process.
Solution Approach 2:
The system enables continuous operation from rough machining through core removal to finishing operations. By storing multiple machining programs and automatically executing them in sequence, the system maintains continuous productive action without interruption for manual intervention.
2Extent of automation
If automatic core removal is implemented, then continuous operation from rough machining to finishing is enabled, but device complexity increases due to additional control functions
Solution Approach 1:
The control unit serves multiple functions: it controls the wire electrical discharge machine for rough machining, stores machining programs, coordinates core removal operations, and manages finishing operations. This multi-functionality reduces the need for separate dedicated control systems for each operation.
Solution Approach 2:
The system merges the control functions for rough machining, core removal, and finishing operations into a unified control architecture. The control unit integrates program storage, operation coordination, and process management into a single system, simplifying the overall control structure despite the increased automation.
