Patent ID: 8607466

Claim:
A coordinate measuring machine for determination of at least one spatial coordinate of a measurement point on an object to be measured, comprising: a base; a probe head for approaching the measurement point; a frame structure for linking the probe head to the base, the frame structure including: at least a first and a second frame component; and at least one linear drive mechanism moveably linking the first and the second frame components, for provision of movability of the probe head relative to the base in a first direction; at least a first mechanical reference element extending over the linear drive mechanism and at least a part of the first frame component, wherein the first reference element being fastened fixedly to the first frame component, in a substantially unloaded way; and two or more displacement sensors assigned to the first reference element, the first reference element and the two or more displacement sensors being designed and arranged in such a way, that distances from the first reference element to the first and the second frame components are measurable, wherein the distances measured by the displacement sensors indicate a displacement of a movable member of the linear drive mechanism from an ordinary bearing position and a deformation of the first frame component.
