Abstract
In dimensional metrology, a datum system is used for defining a coordinate system to enable the evaluation of geometrical tolerances of workpieces. With regard to function-oriented tolerancing representing the workpiece’s function optimally, the physical workpiece contact has to be recreated by the datum system. Therefore, a new registration approach is used, where contact points of the acquired measurement point clouds determine the datums. In this paper, the propagation of the measurement uncertainty of contact points towards the registration result is discussed, having an impact on derived measurands.
