Abstract

In probing by scanning a workpiece (71) to be measured using a coordinate measuring machine a stylus tip is moved before the scanning along a scanning path (73) along an initialization path (83) or/and after the scanning path (73) along a finalization path (85). A length (Lv, Ln) of the initialization path, respectively finalization path, is chosen in dependence of parameters of a concrete measuring task, in particular in dependence of a pre-determined scanning speed, a stiffness of the stylus or a mass of the stylus.
