| 摘要 |
The present invention relates to a coordinate measuring machine comprising a stationary base, a probe head, at least one linear drive mechanism for moving in a first direction, the linear drive mechanism having a linear guide and a movable member being supported for movement along the guide by bearings. The linear drive mechanism further comprises at least a first pre-calibrated integral sensor-package having at least two displacement sensors each for measuring a distance from the movable member to the guide in a direction being non-parallel with respect to the first direction, wherein the sensed distances indicate a translational displacement of the movable member from an ordinary bearing position in a direction perpendicular to the first direction and a rotational displacement of the movable member. |
