Solution Overview
Problem
Current methods for measuring workpieces with coordinate measuring machines lack standardized specification data, leading to inefficiencies and errors in defining measurement processes and evaluating results, resulting in inconsistent results across different locations and technicians.
Innovation Solution
The method involves using existing test features with associated data to define measurement sequences and evaluate results, reducing the effort required by determining similarity criteria such as dimension, tolerance type, and permissible range, and retrieving stored data for default specifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If measurement parameters and evaluation specifications are manually specified by the user, then the measurement process can be defined and executed, but the effort and time required increase significantly and errors are more likely to occur
Solution Approach 1:
The patent stores measurement parameters and evaluation specifications from previously executed measurement processes in a database. Before a new measurement, these pre-stored parameters are automatically retrieved and assigned as default values, eliminating the need for manual re-specification and ensuring consistency with proven measurement configurations.
Solution Approach 2:
The system creates copies of measurement parameters and evaluation specifications from existing test features in the database. These copied parameters serve as templates that can be automatically assigned to new measurement tasks, reducing manual input effort while maintaining reliability through proven configurations.
2Adaptability or versatility
If different users specify measurement parameters manually, then each user can customize the measurement process, but the results become inconsistent and less comparable across different locations and technicians
Solution Approach 1:
The system automatically retrieves and assigns measurement parameters and evaluation specifications from the database without requiring manual user input. This self-service approach ensures that the same proven parameters are used consistently across different users and locations, improving result comparability while still allowing users to review and adjust parameters if needed.
Solution Approach 2:
The patent ensures homogeneity in measurement processes by automatically assigning identical measurement parameters and evaluation specifications from the database to similar measurement tasks. This standardization eliminates variations introduced by different users, making results comparable across different locations and technicians.
3Measurement precision
If detailed measurement parameters are manually specified for each measurement, then measurement accuracy can be optimized, but the complexity of the measurement setup process increases
Solution Approach 1:
Measurement parameters that have been proven to yield accurate results are pre-configured and stored in the database from previous successful measurements. Before executing a new measurement, these pre-optimized parameters are automatically retrieved and assigned, maintaining measurement accuracy while eliminating the complex manual setup process.
Solution Approach 2:
The system copies proven measurement parameter configurations from the database for similar measurement tasks. This copying approach preserves the measurement accuracy achieved through careful optimization while significantly reducing the complexity of setting up new measurements, as users don't need to manually specify each parameter.
4Productivity
If measurement parameters are not specified beforehand, then the measurement process can start quickly, but the quality and reliability of the measurement results deteriorate
Solution Approach 1:
Measurement parameters and evaluation specifications are pre-stored in the database from previous measurements. Before the measurement process begins, these parameters are automatically retrieved and assigned in the background, allowing the actual measurement to start quickly without compromising result quality, as the parameters are already optimized.
Solution Approach 2:
The system automatically retrieves and assigns appropriate measurement parameters from the database based on the measurement task requirements, without requiring manual user specification. This self-service approach ensures that high-quality, proven parameters are used while maintaining fast measurement execution, as the parameter assignment happens automatically.
