Abstract
significantly reduce the efforts associated with the traceability of industrial dimensional metrology laboratories
by means of the almost exclusive use of coordinate measuring machines (CMMs) in combination with laser
interferometers. The second main goal was to develop and validate CMM-specific methods for task-related
measurement uncertainty analysis. In this paper, significant achievements from the EASYTRAC project are
reported, with particular emphasis on : i) error compensation using reversal techniques; ii) use of laser
interferometers on CMMs to reduce measuring uncertainty when calibrating standards of length; iii)
development of other task-specific calibration techniques; and iv) use of multiple measurements strategies for
uncertainty assessment. Uncertainty analyses of virtually any measurable feature were performed and
validated, including freeform, gear and thread parameters. This work has provided an extensive experimental
basis for the elaboration of the ISO/TS 15530 series of standards.
