ABSTRACT:
The invention is directed to a method wherein measured values are mathematically combined with stored corrective values. The measured values are determined during the form measurement on circularly-shaped, cylindrical or spherically-shaped geometric elements by a coordinate measuring apparatus. To determine these corrective values, circularly-shaped or circular-segment shaped measurement lines each having several different diameters are scanned at different speeds in several positions or planes of the coordinate measuring apparatus. The form deviations corresponding to the diameters and the speeds which are measures on the known form are stored. In addition to the variables of diameter and scanning speed, the corrective values can be parameterized in accordance with the wavelength constant of the filter used, the position in the measuring region and peripheral direction of the measurement.
