Current issues in uncertainty of dimensional tolerance metrology and the future development in the domain of tolerancing

Abstract

Uncertainty is an integral part of measurement result. Moreover, any problem in the specification of tolerance or in the measurement phase of tolerance is related to uncertainty, but few methods and lack of experimental data are available to integrate this knowledge. In this work we present the current situation of uncertainty in GD & T, analyzing at the same time a future prospective and including some specific areas to be taken into consideration.
