1Adaptability or versatility
If multiple tool setups are used for bending different components, then the versatility of the bending machine is improved, but the total tool change time increases and processing efficiency deteriorates
Solution Approach 1:
The system performs preliminary analysis of all required tool setups and determines the optimal processing sequence before actual bending operations begin. By calculating setup change times and using search algorithms (such as A* search) in advance, the system pre-determines the sequence that minimizes total tool change time, avoiding reactive optimization during production.
Solution Approach 2:
The system dynamically optimizes the processing sequence based on the specific characteristics of components and tool setups. Rather than using a fixed processing order, the system adapts the sequence to minimize tool changes by analyzing component requirements, tool compatibility, and setup change times, making the processing plan flexible and optimized for each specific production scenario.
