Engineering Contradiction Analysis
1Reliability
If traditional actual tests and repeated adjustments are used to select cutter and coating combinations, then comprehensive performance data can be obtained, but the process is time-consuming and inefficient
Solution Approach 1:
The system performs preliminary actions by conducting experiments under different combinations of cutter parameters and coating parameters beforehand to establish a performance-prediction model. This model can then quickly predict the optimal combination for new workpieces without requiring actual tests, thus saving time while maintaining reliability.
Solution Approach 2:
The system creates a virtual copy of the actual testing process through simulation. By using a performance-prediction model that replicates the behavior of actual machining, the system can evaluate different cutter-coating combinations virtually, avoiding time-consuming physical tests while maintaining selection accuracy.
2Manufacturing precision
If traditional actual tests and repeated adjustments are used to select cutter and coating combinations, then performance data can be gathered, but the process is tedious and difficult to ensure optimal matching
Solution Approach 1:
The system replaces the mechanical process of actual testing and manual adjustment with an automated information-processing system. The performance-prediction model and genetic algorithm automatically analyze workpiece parameters, predict optimal combinations, and provide recommendations, eliminating the need for tedious manual tests and adjustments while ensuring high matching quality.
Solution Approach 2:
The system enables self-service by automatically selecting optimal cutter-coating combinations based on workpiece parameters without requiring manual intervention for testing and adjustment. The performance-prediction model and optimization algorithms autonomously determine the best matching, reducing complexity and ensuring consistent quality.
3Measurement precision
If more actual tests are conducted to find the best combination, then selection accuracy improves, but time consumption and costs increase
Solution Approach 1:
The system changes the approach from varying physical parameters through actual tests to varying digital parameters in simulations. By inputting different cutter and coating parameters into the performance-prediction model, the system can evaluate numerous combinations rapidly in silico, achieving high identification accuracy without the time and cost penalties of physical testing.
Solution Approach 2:
The system performs preliminary experiments to build the performance-prediction model, which then enables rapid prediction of optimal combinations for future applications. This preliminary investment creates a reusable knowledge base that maintains high selection accuracy while dramatically improving productivity for subsequent cutter-coating selection tasks.
