A process for the correction of guiding errors in the case of a coordinate measuring apparatus

摘要

A method of correcting the guiding errors in the case of a coordinate measuring apparatus (10), comprising a movable measuring head (30) and means (14, 20) for the guidance of the measuring head (30) in at least two different spatial directions (16, 22, 24), along at least two first measurement lines (49; 108, 110; 128, 130, 132) of the same first spatial direction of the correction values are ascertained and in a data memory (40) are stored in order to correct the displacement errors, characterized in that the longitudinally of the at least two first measurement lines (49; 108, 110; 128, 130, 132) determined correction values are altered in such a way that the changed correction values of this measurement lines (49; 108, 110; 128, 130, 132) in the intersection point of these measurement lines (49; 108, 110; 128, 130, 132) with a first measurement line (112; 134) of a second spatial direction assume a predetermined value and only relative changes with respect to the predetermined value, which reflect.
