- Abstract:
- Virtual experiments and digital twins are virtual representations of simulation processes and can aid in crucial tasks, such as interpreting measurement data or evaluating uncertainties. Therefore, virtual experiments and digital twins are essential components in the digital transformation in metrology. However, it is important that the digital model is properly validated, to make sure its output is reliable. This research shows how to validate a virtual coordinate measurement machine (CMM) by means of reference measurements. The output of the digital model is compared to reference measurements of a ring gauge and its consistency is evaluated. The results show that the output of the digital model for the diameter of the ring gauge is consistent with the reference data. The roundness measurements seem to contain an inherent bias, introduced by the CMM. After correcting for this bias, the output of the digital model for the roundness of the ring gauge is also consistent with the reference data.
