Abstract:
A coordinate measuring machine compensates for hysteresis error caused by friction at the non-driven end of the bridge. The bridge may have a single drive and/or a single scale. The methods, systems, and apparatuses compensate for errors in the x-direction and/or errors in the y-direction caused by rotation of the bridge. Some embodiments compensate for hysteresis errors in the x-direction caused by a vertically-movable ram.
