Abstract

The invention is directed to a coordinate measuring apparatus wherein the drives (3, 5, 6) for the measuring sleds of the apparatus are controlled on circularly-shaped paths to machine-control adjust the spatial orientation of the probe pin 9. The probe pin is attached to a passive rotation-pivot joint and has a probe ball which is driven into one of several centering gaps of a body 10. In this way, a separate drive for the rotation-pivot joint 8 is not needed.
