TS EN ISO 10360-6

TS EN ISO 10360-6 addresses acceptance and reverification tests for coordinate measuring machines by focusing on the software used to compute associated features from measured coordinate data. In practical terms, it is concerned with estimating errors in the calculation of Gaussian associated features, so the standard looks beyond the machine hardware and into the software layer that turns measured points into usable geometric results.

What Gaussian associated features mean in coordinate metrology

In general coordinate metrology, a set of measured points is processed to derive an associated feature such as a line, plane, circle, cylinder, or other ideal geometric element. A Gaussian associated feature is commonly understood as a best-fit result based on least-squares principles. That makes the computation method important: the same measured data can yield different results if the fitting rules, numerical implementation, or data handling differ. This standard therefore targets the evaluation of software that performs those calculations.

Why software verification matters for CMM results

The document’s explicit scope is the control of software used to compute associated features from coordinate measurements. That distinction matters because CMM performance is not determined only by probing and machine geometry; the interpretation of point data also shapes the final result. In real-world use, this affects inspection consistency, comparability between systems, and confidence in derived geometric values.

• The focus is software for associated-feature calculation, not a general CMM hardware performance test.
• Gaussian fitting is a core concept in deriving ideal geometry from measured points.
• The method is intended for both acceptance testing and reverification over time.
• Its purpose is to reveal calculation-related errors in the measurement workflow.
