Patent ID: 7043334

Claim:
A method of operating a multi-axes processing device with an associated processing head for improving its position accuracy, comprising the steps of controlling a position change of the processing device and the associated processing head with a computer; arranging a work region and a calibration region so that the work region and the calibration region occupy a same or similar position in space by a same or similar inclination in horizontal and vertical directions, and reference coordinates of the calibration region correspond to coordinates of the work region, and the processing device and the associated processing head during running through the work region and through the calibration region move in accordance with the coordinates of the work region or the reference coordinates of the calibration regions, and assume work poses which are same or similar work poses; detecting actual work poses of the processing device and the associated processing head and determining presence or absence of deviations of the actual work poses from nominal work poses; and in the event of presence of the deviations, moving the processing device and the associated processing head into the calibration region and post-adjusting the work poses.
