Measurement Protocol Compliance Checks for Coordinate Metrology
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing measurement protocols in coordinate-measuring machines lack reliability, particularly in high-precision and safety-critical components, as they do not ensure adherence to predefined conditions during measurement sequences and evaluation of examination features, leading to potential errors and inaccuracies.
Innovation Solution
A method that involves providing specification data for measurement sequences and examination features, checking compliance with these conditions, and documenting compliance or non-compliance in the measurement protocol, ensuring that measurements are performed and evaluated according to predefined standards, thereby enhancing the reliability of measurement results.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If measurement protocols are created with user flexibility in defining examination plans and measurement sequences, then ease of operation and adaptability are improved, but reliability and trustworthiness of measurement results deteriorate due to lack of enforced standards
Solution Approach 1:
The patent applies preliminary action by defining and storing specification data that contains predefined conditions for measurement sequences and examination feature evaluation before the actual measurement process. These specifications include required measurement points, evaluation methods, and acceptance criteria that are established in advance and automatically checked during measurement execution, ensuring reliability while maintaining user flexibility in creating examination plans.
2Device complexity
If measurement protocols document only final results without documenting compliance with measurement conditions, then device complexity is reduced, but reliability and traceability of measurement results deteriorate
Solution Approach 1:
The patent implements feedback by automatically checking measured data against the stored specification data and documenting the compliance results in the measurement protocol. The system provides feedback on whether predefined conditions were met, including documentation of measurement points visited, evaluation results, and any deviations from specified requirements, thereby enhancing traceability without significantly increasing protocol complexity.

AI summary
A method for creating a measurement protocol in a computer, such as the measurement computer of a coordinate-measuring machine or a computer remote therefrom, includes: providing data necessary for creating a measurement protocol generated on the basis of a measurement sequence by the coordinate-measuring machine; providing specification data specifying predefined conditions under which a measurement sequence should be performed and/or specifying predefined conditions under which examination features should be evaluated; checking the data necessary for creating a measurement protocol as to whether the predefined conditions under which the entire measurement sequence should be performed were met and/or as to whether the predefined conditions under which individual examination features to be examined should be evaluated were met; and, creating a measurement protocol in the form of an electronic document, in which compliance and/or non-compliance with the conditions in accordance with the specification data is documented in the measurement protocol.
