Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual parameter adjustment is performed one by one, then the parameters can be measured to meet the standard, but the measurement process takes much time and consumes a lot of workpieces
Solution Approach 1:
The system captures feedback signals from the controller that instruct shafts to move along a machining route, and uses this feedback to automatically calculate shaft locations and adjust parameters. This closed-loop feedback mechanism eliminates manual parameter input and testing, enabling automatic measurement and adjustment of controller parameters to meet standards without time-consuming manual operations.
Solution Approach 2:
The measuring system automatically performs parameter measurement and adjustment without manual intervention. The capturing module captures feedback signals, the transforming module converts coordinate systems, the processing module calculates true round trajectories, and the adjusting module automatically adjusts controller parameters based on calculated locations, making the system self-sufficient and eliminating the need for manual parameter input and testing.
2Measurement precision
If manual parameter adjustment is performed one by one, then the parameters can be measured to meet the standard, but a lot of workpieces are consumed for testing
Solution Approach 1:
The system uses a virtual model approach by calculating the true round trajectory of the machining route on an inclined plane as reference information. Instead of physically testing on multiple workpieces, the system creates a digital representation of the expected trajectory and compares actual shaft locations against this virtual model, eliminating the need to consume multiple physical workpieces for testing.
Solution Approach 2:
The system replaces the mechanical testing process with computational methods. Instead of manually adjusting parameters and physically testing on workpieces, the system uses coordinate transformation algorithms and trajectory calculations to determine parameter accuracy, substituting physical mechanical testing with digital computation and analysis.
3Reliability
If manual parameter adjustment is performed, then the operating states can be tested one by one, but the overall process does not meet the measurement cost requirement
Solution Approach 1:
The measuring system integrates multiple functions into a single automated platform: the capturing module captures feedback signals, the transforming module performs coordinate system conversions, the processing module calculates trajectories, and the adjusting module adjusts parameters. This multi-functional integrated system replaces multiple separate manual operations, reducing overall system complexity while improving reliability through automated verification of operating states.
4Productivity
If automatic parameter adjustment is implemented, then measurement time is reduced and workpiece consumption is lowered, but the system requires complex coordinate transformation and trajectory calculation
Solution Approach 1:
The system pre-calculates the true round trajectory of the machining route on an inclined plane as reference information before actual parameter measurement. By establishing this virtual reference model in advance through coordinate transformation, the system eliminates the need for complex real-time calculations during parameter adjustment, thereby improving measurement efficiency while managing computational complexity through preliminary preparation.

AI summary
A contour accuracy measuring system and a contour accuracy measuring method are provided. The contour accuracy measuring system captures location coordinate data of shafts of a machine tool. The location coordinate data are calculated to obtain a first true round trajectory on an inclined plane as reference information. The contour accuracy measuring system then adjusts parameters of the locations of the shafts based on the location coordinate data of the shafts of the reference information to generate a second true round trajectory on the inclined plane, so as to get to know whether the locations of the shafts after the parameters are adjusted comply with a standard. Therefore, the overall measurement process can be speeded up by automatically measuring the parameters and automatically testing an operating status.
