On the basis of the condition that the distances between planes be measured in accordance with the ISO guide "Uncertainty of Measurement", the uncertainty of measurement of a CMM in the orthogonal coordinate system has been obtained by carrying out a systematic experiment. So the expanded uncertainty is given as 4.4μm.
