Classification: CPC B  G | IPC B  G

Claim 4:
5. The method according to claim 1, which further comprises:
deflecting the measurement bean by respective positive and negative fixed magnitudes in the workpiece support plane by titling the processing mirror scanner about one, first tilt axis thereof and, with the processing mirror scanner fixed in the respective titled scan positions, capturing a linear height edge disposed at the workpiece support plane by using the measurement sensor for a respective line scan of the measurement beam by deflecting the measurement mirror scanner about one, second tilt axis thereof, and ascertaining an axis of the processing coordinate system based on captured points of intersection of the two line scans with the height edge;
deflecting the measurement beam by respective positive and negative fixed magnitudes in the workpiece support plane by tilting the measurement mirror scanner about the other, first tilt axis thereof and, with the measurement mirror scanner fixed in the respective tilted scan positions, capturing the height edge by using the measurement sensor for respective line scans of the measurement beam by deflecting the processing mirror scanner about the second tilt axis thereof;
ascertaining an axis of the measurement coordinate system based on the captured points of intersection of the two line scans with the height edge; and
determining a rotational deviation between the processing and measurement coordinate systems based on the ascertained axes of the processing and measurement coordinate systems.
