QUALITY MEASUREMENT ON CMM

摘要

In the first section we wile discuss the sources of errors and uncertainties of the Coordinate Measuring Machine (CMM). The mastery of this process depends on a good knowledge of the initialisation methodology of the CMM. Afterwards, we will propose a new method for calculating an A-type uncertainty on the probe system calibration. Our data-processing model provides automatically the value of uncertainties. This information enables a user to control the quality of the probe system calibration. The knowledge of these uncertainties is strategic because they will be propagated in all the other measurements.
