Abstract: An adjustable device is disclosed comprising two relatively re-orientatable members each having a lockable universal joint, and a connecting member for connecting the two relatively re-orientatable members whereby when the two relatively re-orientatable members are connected the two joints are in mechanical communication via the connecting member. The two lockable joints may be locked and unlocked using an actuator, a lever, which may act on a compression device in order to render the lockable joints either mobile or locked. The compression device may cause a change in cross-sectional area of the tube over at least a part of its length. At least one of the lockable universal joints may provide for linear movement between the two relatively re-orientatable members. Also disclosed is an apparatus for the simulation of the orientation of a sample with respect to a cutting tool or scanning probe and method for aligning the adjustable device.

Abstract: A method of calibrating a scanning system comprising a machine and a measuring probe, includes the steps of error mapping the system statically and qualifying the stylus tip so that the system will provide accurate measurements, determining the positions of a number of datum points on the surface of an artefact with the probe stylus in contact with the workpiece and at zero deflection normal to the surface, scanning the surface through the datum points at a nominal stylus deflection and at the maximum speed which provides repeatable position measurements to make a second determination of the positions of the datum points, determining the errors attributable to the scanning process by subtracting the positions obtained in the first and second determinations, and storing the error values for correction of subsequent measurements of similar artefacts.

Abstract: A coordinate positioning machine has an operating module such as a tool or probe (10) mounted for translational motion relative to a table (16) with three degrees of freedom by means of three articulated linkages (18). Each of the linkages is made up of a torsion box (22) which is pivotally mounted to a vertical pillar (20) with one degree of freedom, and a pair of struts (26), each of which is pivotally mounted with two degrees of freedom to the torsion box at one end, and to the operating module at the other. The linkages cooperate to prevent all rotational motion of the operating module, while allowing translation. Motion of the operating module is actuated manually, and the mass thereof is counterbalanced by an articulated counterbalance arm 90 which guides a cable 96 that is in turn connected to a fusee. Displacement of the operating module is measured using scale and readhead encoders (40,50). Motion of the operating module can be restricted to a single plane by means of locking devices (132) operating between the struts 26, thereby to enable scanning of a surface in a series of parallel planes.

Abstract: A touch probe has a sensing module 10 and a stylus module 12 magnetically retained and kinematically located thereon. A stylus holder 102 is biased into a kinematic rest location within the stylus module 12. The sensing module 12 has a fixed structure provided by connector 14, cylindrical housing 16, and circuit supporting structure 18. An intermediate load member 30 is connected to structure 18 at one end by means of a relatively resilient diaphragm 40 and at the other by three supporting struts 50, extending at an angle of 45.degree. to the axis A. The load member 30 carries a circular retaining plate 22 upon which the stylus module 12 is located. During a measurement operation, a force applied to stylus tip 112 will cause bending of struts 50, and deformation of diaphragm 40 prior to movement of the stylus holder 102 out of its kinematic rest position. Strain gauges provided on the struts 50 detect this bending and generate an output signal accordingly.

Abstract: A touch trigger probe for a coordinate measuring machine or machine tool has a stylus (14), which is biased into a rest position. The stylus has two independent supports, provided within a housing (10). In the embodiment of FIG. 1, the first support comprises a skirt (18) of a stylus holder (12), which is axially constrained on a surface (20) of the housing (10). The second support comprises a kinematic arrangement of cylinders (34) and balls (36), together with a planar spring (30), which together provide lateral constraint. The first support is biased by a much lighter force than the second support, so that its friction is very low. This reduces the lobing and hysteresis of the stylus movement, and thereby increases the accuracy of the probe.

Abstract: A touch probe for use on a coordinate positioning machine includes a stylus module and a sensing module securable to a movable arm of the positioning machine for releasably supporting the stylus module. The sensing module can include a sensor for detecting contact between the stylus and a surface and/or for detecting displacement of the stylus module relative to the movable arm. The stylus includes a support structure, releasably supported by the stylus module, and a stylus-supporting member for supporting the stylus, with the stylus-supporting member being biased into a rest position with respect to the support structure. The stylus-supporting member is displaceable from the rest position and relative to the support structure when a deflection force acts on the stylus, and returns to the rest position when the deflecting force is removed.

Abstract: A magazine has a plurality of storage ports 400 each of which retains a stylus module 314 for use in measuring workpiece dimensions on a coordinate measuring machine. Each storage port 400 is configured as a pair of jaws provided by docking inserts 414. A permanent magnet 418 is mounted on each docking insert 414. The lower casing of the stylus module 314 is urged against the inwardly facing edges 416 of the docking inserts 414 by the magnetic attraction force due the magnets 418. The stylus module 314 is engaged with a retaining module (on the quill of the machine) by moving the retaining module in a downward sense to engage the stylus module 314; further downward movement disengages the stylus module 314 from the storage port 400, thus enabling engagement of such a stylus module and removal of the module from the storage port in a single continuous movement.
