Abstract
Coordinate measurement systems can be universally used for the evaluation of geometrical features of complex, three-dimensional workpieces. However, efficient quality control requires proof of the suitability of the method for the specific measurement task. Therefore, DIN EN ISO 14253¹ demands that the measurement uncertainty is known and in conformance with the specified tolerance (cf. Imkamp and Kistner²). The determination of the measurement uncertainty of coordinate measuring systems can be very complex, since several uncertainty contributions, e.g. of themeasurementmachine, theworkpiece, and the environment, can superimpose each other in various ways for the individual features. There are different
approaches to determine the task-specific measurement uncertainties. This work reports on a simulationbased method and its recent developments, including the support of tactile scanning measurements and the consideration of uncertainty contributions arising from undersampling
of the features. Besides precise determination of input parameters, we provide a novel simplified method allowing users to estimate the expected measurement uncertainty without costly metrological acquisition of all input parameters.
