EUCoM: Evaluating the Uncertainty in Coordinate Metrology
, 2019 Coordinate metrology is a fascinating discipline that bridges a very wide gap between sophisticated mathematics and practical application in industry, and particularly does the evaluation of the uncertainty. On one side, the evaluation is very complex and requires dedicated mathematical and software tools; on the other side, the impact is tremendous in
