Engineering Contradiction Analysis
1Reliability
If manual checking of machining program consistency is performed by operators, then potential tool or workpiece breakage can be prevented, but operator burden increases and checking becomes time-consuming
Solution Approach 1:
The machining program automatically checks its own consistency by extracting tool selection commands, identifying selected tools, and validating subsequent machining commands against tool capabilities without requiring external manual verification. The control device performs self-validation by comparing commanded operations with actual tool characteristics stored in the system.
Solution Approach 2:
The manual mechanical checking process performed by operators is replaced with an automated information processing system that extracts tool selection commands (T codes), identifies tool characteristics from stored data, and validates machining commands through computational comparison, eliminating the need for human operators to manually verify program consistency.
2Reliability
If trial operation is performed to check consistency between tool selection and machining operation, then program errors can be detected, but production time increases significantly
Solution Approach 1:
The system performs preliminary validation of machining program consistency by extracting tool selection commands, identifying selected tools, and validating subsequent machining commands against tool capabilities before actual machining execution. This pre-check prevents errors from reaching the trial operation stage, eliminating time-consuming iterative testing.
3Reliability
If operators carefully check tool numbers in tables while creating machining programs, then incorrect tool selection can be avoided, but the programming process becomes more complex and time-consuming
Solution Approach 1:
The machining program automatically validates its own tool selection accuracy by extracting T codes, identifying selected tools, and checking subsequent machining commands against stored tool characteristics. This self-validation eliminates the need for operators to manually cross-reference tool number tables, simplifying the programming process while maintaining accuracy.
Solution Approach 2:
The control device provides automated feedback by comparing commanded machining operations with the actual capabilities of selected tools based on stored characteristic information. This feedback mechanism alerts operators to inconsistencies without requiring them to manually verify each command against tool specifications, reducing programming complexity.
