Abstract
A work piece is measured by at least one point of a surface of the work piece being sampled by a feeler. The feeler exerts a probing force on the surface and the feeler is deflected relative to a mounting of the feeler. On the basis of the deflection, a position of the point of the surface is determined. A directional dependence of a flexibility of the feeler is determined and/or is known. The feeler and the work piece are positioned and/or oriented relative to each other, while taking into consideration the directional dependence, such that during sampling of the point of the surface unintentional slipping of the feeler on the surface does not occur, or occurs only with low probability, or an unintentional deviation of the feeler from an intended path on the surface does not occur, or occurs only with low probability.
