Paper Abstract

The main results of an industrial inter-laboratory comparison for CMMs equipped with optical sensors are presented in this paper. The comparison, named VideoAUDIT, was organized and coordinated by the Laboratory of Industrial and Geometrical Metrology - University of Padova - and carried out in Italy and Switzerland from August 2007 to June 2008. A total of 16 CMMs from different companies participated in the Project, using different kinds of optical sensors. The participants were asked to measure a set of calibrated artefacts, following detailed procedures. The Audit items have been chosen with the following criteria: (1) objects that can be measured with different types of optical sensors and (2) including both reference artefacts for performance verification and common industrial products. Special attention has been paid to the design of the comparison in order to respect the proficiency testing rules; in particular, the long term stability of the audit items was checked during the comparison as a main requirement. An important task of the comparison was to test the ability of the participants to determine the uncertainty of their measurements.
