Abstract
The present invention relates to a machine frame, and particularly but not exclusively, to a machine frame for so-called coordinate measuring machines of the kind which include at least one first portal that includes two parallel, vertical first and second legs (7, 8) which are rotationally and flexurally rigid in relation to a base member (10). The legs support a horizontal beam (11) on which there is movably supported a rod, bar or the like for supporting a measuring head, tool or corresponding device. The horizontal beam (11) is connected to the first leg (8) by a pivot joint (13) which permits the beam (11) to rotate in the vertical plane of the legs (7, 8), and is connected to the second leg (7) by a connection (14) which permits the beam (11) to rotate in this vertical plane and also to move in the direction of its longitudinal axis in relation to the second leg. The invention also relates to a method of determining the geometry of the portal occasioned by deformation of such machine frames.
