摘要

Coordinate measuring machine for determining at least one spatial coordinate, error compensation method in a coordinate measuring machine and method for determining at least one spatial coordinate of a coordinate measuring point The present invention relates to a coordinate measuring machine (1) comprising a fixed base (3), a probe head (6), at least one linear drive mechanism (2x, 2y, 2z) for moving in a first direction the measuring mechanism linear drive (2x, 2y, 2z) having a linear guide (4x, 4y) and a movable member (5x, 5y) being supported for movement along the guide by the bearings (71x, 72x, 73x, 74x, 71y, 72y, 73y, 74y). the linear drive mechanism (2x, 2y, 2z) additionally comprises at least one first pre-calibrated integral sensor package (101x, 102x, 101y, 102y) having at least two displacement sensors (91x, 92x, 93x, 94x, 95x, 91y, 92y, 93y, 94y, 95y) each being to measure a distance from the movable member (5x, 5y) to the guide (4x, 4y) in a direction not parallel to the first direction (x, y, z), where the perceived distances indicate a translational displacement of the moving member (5x, 5y) from a usual rolling position in a direction perpendicular to the first direction (x, y, z) and a rotation displacement of the moving member (5x, 5y).
