A method of constructing a machine stand, particularly a machine stand for so-called coordinate measuring machines, comprises one or more vertical legs (16, 17) and one or more horizontal beams (15), and a rod or bar (3) or the like which is mounted in a horizontal beam and intended to carry a measuring head (1), tool or the like. At least one vertical leg is supported by a base element (18). The leg at least supports one beam and the rod can be moved any selected point within the space volume defined by the stand, by moving the leg, the beam or beams and the rod relative to the base element. The element is characterized in that at least one of the vertical legs, a first leg, (16), is mounted relative to the base element so as to be flexurally rigid and non-rotatable about its longitudinal axis; and in that the beam or beams (15) is/are not non-rotatably and flexurally rigidly connected, so that a yielding structure will be obtained. According to one preferred embodiment, deformation of the first leg (16) is measured by measuring means, so as to be able to determine deformation of the structure. The invention is shown to be applicable to several different types of machine stand. The invention also relates to a machine stand. <IMAGE> |
