Determining component height deviations

Heights of components or parts thereof are measured within a printing machine by measuring their relative rather than absolute heights. A virtual surface 16 may be constructed from the measured heights, with a tolerance level 17 employed based on the virtual surface. In use, a height sensor 10 measu...

Beschreibung
Zusammenfassung:	Heights of components or parts thereof are measured within a printing machine by measuring their relative rather than absolute heights. A virtual surface 16 may be constructed from the measured heights, with a tolerance level 17 employed based on the virtual surface. In use, a height sensor 10 measures the relative heights of at least three locations. The invention is particularly suited to measurement of tooling components within a printing machine, such as tooling pins 14, allowing components 14b that are out of tolerance to be identified.
