Abstract
Measured position data (Px, Py, Pz) are combined with stored correction values (DB) describing the elastic bending behavior of a coordinate measuring machine in that parameters characterizing the bending behavior are determined for several positions of the probe of the machine within the measuring range (30) of the machine, the acceleration-dependent components of these parameters are determined and stored in the form of correction values (c11, c22) which describe the bending behavior of the coordinate measuring machine as a function of the position (Px, Py, Pz) of measuring slides (22, 23, 24), and at least of the acceleration (ax, ay, az) of the measuring slides introduced via the drives, the correction values being combined with measured position data (Px, Py, Pz) of the coordinate measuring machine in subsequent coordinate measurements on workpieces.
