This report is made 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.
The Centre for Geometrical Metrology (CGM) at the Technical University of Denmark takes care
of free form measurements, in collaboration with DIMEG, University of Padova, Italy.
The present report describes a software module, MULTICAL, to be used for the calibration of
free form objects. The purpose of the software is to calculate the uncertainty of free form
measurements according to the method described in the draft standard ISO/WD 15530-6.
