Abstract:
Coordinate measuring machine (CMM) are widely used to check geometry of mechanical objects. While applying a coordinate measuring machine to measure a mechanical element, many factors affect the measurement uncertainty. There are a few techniques for assessing uncertainty of measurement, as defined in the ISO Guide to the Expression of Uncertainty in Measurement (GUM). This paper presents a technique for assessment of measurement uncertainty for results of measurement obtained by a CMM and by using calibrated workpieces. The appropriate conclusions will be made based on analysis of the results of measurements.

Key words:
CMM, Measurement uncertainty

Thematic field:
Production and Computer-Aided Technologies
