Measurement uncertainty integrated with the model of product and measurement realization in 3D metrology

Abstract:

Although coordinate metrology has been proven to be priceless to industries and despite the existence of methods to estimate uncertainties, e.g. sensitivity analysis, computer simulation, experimental method; uncertainty has been barely assessed and stated for industrial measurements. Part of that perception may be attributed to a restricted way of employing the uncertainty concept, which is not compatible with the growing importance of metrology. The merging of the product and measurement realization process with the uncertainty concept is outlined in this work. The underlying idea is to use in a rational sense different uncertainty evaluation techniques, where the estimated accuracy required to uncertainty estimation defines the most suitable technique. Within the proposed context, the drawing-up of classical uncertainty budgets for GPS characteristics are shown and discussed.
