This report was produced as a part of the project EASYTRAC, an EU project under the
programme Competitive and Sustainable Growth: Contract No. G6RD-CT-2000-00188,
coordinated by UNIMETRIK S.A. (Spain). The project is concerned with low uncertainty
calibrations on coordinate measuring machines (CMMs).
For this project, the Centre for Geometrical Metrology (CGM) at the Technical University of
Denmark (DTU) has taken care of freeform measurements, in collaboration with the
Dipartimento di Innovazione Meccanica e Gestionale (DIMEG) - University of Padova - Italy.
The present report describes feasibility and experimental results of calibrations of freeform parts
on CMMs as contribution to development of the ISO 15530 series of standards currently under
consideration by the ISO TC 213/WG10.
