• A complete measurement result consists of the measurement value and its measurement uncertainty. The knowledge of the uncertainty is, above all, of economic importance as it is a prerequisite for making a reliable statement on the quality of a measurement. Based on a traceable determination of measurement results, the production processes can be evaluated and controlled in a targeted way. Particularly with regard to the manufacture of highly accurate workpieces with constantly decreasing tolerances this leads to less complaints and thus to high cost savings. The determination of the measurement uncertainty is, however, complex and has, as a matter of principle, to be estimated for each measurement individually. Therefore, the method of the "Virtual Coordinate Measuring Machine" (VCMM) has established itself for some time now in coordinate metrology for a realistic, fast and automatic determination of the measurement uncertainty on prismatic workpieces. Within the scope of a German research project, the Physikalisch-Technische Bundesanstalt (PTB), in cooperation with partners from industry, has transferred this approach to the gear metrology. The aim was the development of an industry suited procedure for a computer-simulated determination of an ISO-compliant measurement uncertainty for involute gear measurands. Thus, the extended VCMM for gear measurements guarantees traceable gear measurements and provides the prerequisites for a modern quality management system.
