摘要： The four components of the deviations of a rotary table from an ideal axis of rotation can be obtained by a single measuring method wherein a test body (4) having a plurality of well-defined measurement points is placed on the rotary table (1) and the positions of said measuring points are then determined by means of a coordinate-measuring instrument (3), for each of various angular positions of the rotary table, there being thus a set of ascertained measurement-point coordinates for each of the angular positions of the rotary table. From the sets of measurement-point coordinates, the travel deviations f.sub.a, f.sub.r and f.sub.t of the axis of rotation, and the angle-position deviation p.sub.w are then determined by calculation.

摘要： For accurately determining the position of a measuring head 14, a multicoordinate measuring machine has an additional measuring device, which essentially is formed by a scanning head 19 having a measuring probe 20, and inserted in a beam 16. The position of a cross arm 6 in a distance A is determined by means of the measuring probe 20 and is passed on over an amplifier 22 to a computer 25 for control and display purposes. The coordinate measuring machine operates with only one length scale 5. The cross arm 6 is supported at its ends and without play on carriages 11 and 12, which can be moved in the X direction in guiding systems 3 and 4, which are arranged parallel to each other.

摘要： A stylus (15) for contacting a workpiece (13) to sense its position is suspended on a movable member (16) within a fixed housing (10). The suspension is by means of three connecting units (20, 30, 40). Taking the connecting unit (20)as an example, the movable member (16) is connected to an intermediate member (22) by a first pair of links (21), while the intermediate member (22) is connected to the fixed housing by a second pair of links (23). The pairs of links are rigid in tension and compression so as to prevent rotation of the stylus about a respective one of the three orthogonal axes X, Y, Z. Nevertheless, the links permit translational movement along all three axes. The similar connecting units (30, 40) likewise permit translation on all three axes, while preventing rotation about a respective one of the axes. The use of two pairs of links (21, 23) with a rigid intermediate member (22) is equivalent to the use of a much longer single pair of links without such an intermediate member, and therefore facilitates a more compact construction of the probe for a given range of translational displacement of the stylus (15).

摘要： A dimensional measuring and checking machine mounts a bridge structure (12) on legs (22) which are supported on a base (10) by air bearings. The varying forces due to travel of a probe mounting carriage (24) create vertical displacements of the bearings and movement of the bridge (12) out of alignment. To compensate for this, and thus enable high accuracy measuring, a chain (34) moves with the bridge (12), rotating a spindle (42) at one end of the machine, and thus moving the legs (22) at that end so levers (48) and pivot blocks (52) vary the height of the bridge (12).

摘要： A roundness measuring machine is described which measures the position of the surface of an object as the object is rotated on a turntable. The machine determines the circle which is the best fit to the measured points and converts the measurements to distances from the best fit circle. An improved algorithm for determining the best fit circle is used in place of the limacon fit. Calculated differences between the measured surface position and the best fit circle are corrected for the effect of measuring the difference in the direction towards the center of rotation of the turntable instead of in the direction towards the center of the circle. Data values are calculated representing points at equal angles around the center of the best fit circle rather than equal angles around the center of rotation of the turntable. The improved accuracy of correction allows the machine to tolerate greater eccentricity of the workplace relative to the turntable, reducing the necessity for accurate centering of the workpiece.

摘要： A machine stand and a method of constructing it particularly a machine stand for so-called coordinate measuring machines. The machine includes one or more vertical legs, one or more horizontal beams, and a rod or bar which is mounted on a horizontal beam and intended to carry a measuring head tool or the like. At least one vertical leg is supported by a base element. The vertical leg supports at least one beam, and the rod can be moved to any selected point within the space volume defined by the stand by moving the leg, the beam and the rod relative to the base element. At least one vertical leg is mounted relative to the base element so as to be flexurally rigid and non-rotatable about its longitudinal axis; the beam or beams are not non-rotatably and flexurally rigidly connected, so that a yielding structure is obtained. Deformation of the first vertical leg is measured by measuring means, so as to be able to determine deformation of the structure.

摘要： Metrological apparatus is provided with a turntable (4) which is movable horizontally and pivotally for centering and levelling. The turntable (4) is supported at three points (A,B,P), one (P) of which is fixed and the other two (A,B) of which are vertically movable by motorized jacks. Centering and levelling is achieved automatically by means of a computer (72) which calculates the required horizontal and pivotal movements of the turntable (4) from data obtained by sensing the workpiece surface with a transducer (12).
