Unformatted text preview: n measurements of workpieces with known shape deviations in pre-defined monitoring fields within the measuring volume of the CMMs, wherein all relevant influence factors are considered. All measurements results are stored in a data- ... 134 A. Weckenmann, S. Beetz and J. Lorz base. All unknown and known systematic deviations of the real process are represented during the experiments. Values and sensitivity coefficients of the influence factors have not to be considered separately, since a documented scenario contains the value of the influence factor together with the assigned measurement uncertainty. By means of continuously recording of the results, a statement about the long-run behavior of the CMM is possible, in reference to several input parameters. Thus, short-termed optimizing of these parameters can be avoided. Based on the gained information the calculation of feature specific measurement uncertainties are already possible an early development stage. So the measurement uncertainty can be considered...
