Abstract

The present invention relates to a coordinate measuring machine (1) for determination of at least one spatial coordinate of a measurement point (13) on an object (12) to be measured. The coordinate measuring machine (1) comprises a stationary base (3), a probe head (6) for approaching the measurement point (13) and a frame structure (15) for linking the probe head (6) to the base (3). Thereby, the frame structure (15) comprises at least a first and a second frame component (14,22,24) and at least one linear drive mechanism (2) moveably linking the first and the second frame components (14,22,24), for provision of movability of the probe head (6) relative to the base (3) in a first direction (X,Y,Z). According to the invention, at least a first mechanical reference element (72) extending along a first part of the frame structure (15) is fastened fixedly to the frame structure (15) in a substantially unloaded way, and at least one displacement sensor (9,9a,9b) is assigned to the first reference element (72), wherein the first reference element (72) and the displacement sensor (9,9a,9b) are designed and arranged in such a way, that a distance from the first reference element (72) to the frame structure (15) in the region of the first part is measurable, the distance indicating a displacement and/or deformation of the frame structure (15) in the region of the first part.
