| Zusammenfassung | In various areas of industrial manufacturing the correct evaluation of Chebyshev geometrical elements has fundamental importance for inspection of products with Coordinate Measuring Machines (CMM). According to standard ISO 1101 these are the default algorithms for accessing form deviation and to calculate certain datums for the evaluation of position deviation. To validate the accuracy of these computations, a network of National Metrological Institutes (NMIs) and Designated Institutes (DIs) established an online service which, among other tests, allows manufacturers and users of CMM software to test their mathematical algorithms for Chebyshev. The test covers five important types of associated geometrical elements which are calculated by the so-called Minimum-Zone criterion (MZ). By registration at the TraCIM (traceability for computationally-intensive metrology) online service a user can order the test for validation of his algorithms. Each test contains fifty individual data sets. The users’ evaluation results are compared against reference results provided by the institution offering the test. Procedures for the comparison cover numerical uncertainties of the reference results and maximum permissible errors (MPEs) specified by the user. For each test an online report including detailed test results is issued. Test data, test procedure and test evaluation are subjected to quality rules specified and controlled by TraCIM e.V. which is an international head organization for metrological algorithm validation.
