摘要： An articulating probe head includes motors 12 and 18 for driving respective output shafts 14 and 20 about respective orthogonal axes z and x to move a stylus 22 over the surface of a workpiece under the control of a controller 26. At least one of the motors is inertia balanced by mounting the stator 32 of the motor on bearings 42 to allow it to rotate in opposition to the rotation of the rotor 34. Control of the speed of the spinning stator is achieved by connecting it to the winding assembly 46 of an additional “back-to-earth” motor 47 the magnet assembly 48 of which is connected to the housing. The motor 47 acts as a brake to prevent overspeeding of the rotatable stator, and can have power supplied to it to ensure that the stator does not slow down excessively when the main motor is running at constant angular velocity. Control of the power supply to the motors is achieved by the controller 26.

摘要： Apparatus which can be used to calibrate, or provide measurement data on, a machine. The apparatus comprises two structures each with three spherical supports spaced in a triangular array thereon. The supports may be balls or sockets. The structures are interconnected by six members and each support has the ends of two members connected to it. The members are passive extensible measuring bars and the structures are respectively connected to fixed and movable parts of a machine so that movement of the machine parts causes relative movement between the structures and varies the lengths of the measuring bars. From measurements of the lengths of the measuring bars the actual movement of the machine part can be determined. Calibration of the spherical supports is carried out using a measuring bar which is pre-calibrated in a Zerodur jig.

摘要： A measuring probe includes a suspension module 112 in which a stylus holder 140 is suspended from a housing on a pair of diaphragms 142, 144. At least one of the diaphragms is formed with spiral cut-outs whereby the stylus, which is connected at the centre of the diaphragms, is able to move transversely of the axis of the housing as the stylus holder pivots when transverse forces are applied to the stylus tip. A transducer module 110 is releasably supported on the suspension module by a kinematic mounting 116, 118 and is retained in position by magnets 120. The transducer module contains optical transducers 200, 210, 220 for measuring the deflection of the stylus.

摘要： A coordinate positioning machine comprises a fixed structure including a table and a supporting frame, rigidly connected together. A movable arm is suspended from the frame by means of three powered telescopic struts, each of which is universally pivotally connected to both the arm and the frame. As a consequence, the movable arm is able to move with three rotational degrees of freedom. Movement of the arm with each of these degrees of freedom is constrained by a passive device, connected to the arm and the fixed structure, and which eliminates all rotational movement of the arm, while simultaneously permitting translation thereof.

摘要： A frequency tuneable or chirped laser device is described that includes a laser cavity formed from a plurality of optical components. The optical components include a laser source for generating a beam of light, a spectral tuning element and one or more further optical components for directing the beam of light on to the spectral tuning element. At least one of the plurality of optical components is moveable in a first degree of freedom; such movement simultaneously altering the effective optical path length of the laser cavity and the tuning frequency of the spectral tuning element. The effective optical path length and the tuning frequency of the device are substantially insensitive to any movement of said at least one moveable optical component in degrees of freedom other than the first degree of freedom. This provides frequency tuning in which mode hopping is suppressed.

摘要： Disclosed is a method of moving an articulating mechanism (22,410) for a measuring device, comprising the steps of: releasing two bodies (14,16, 410a,410b) which form the articulating mechanism allowing relative movement thereof; moving one of the bodies with respect to the other until a desired position is reached; and re-constraining the two bodies so they are relatively fixed, perhaps as part of a locking process, characterised in that relative movement prior to re-constraining at the desired position occurs under particular conditions. The particular conditions including moving from the same direction; and stopping, slowing down or maintaining the condition at a position adjacent to the desired position. Also disclosed is a method of positioning an articulating mechanism (22,410) for a measuring device which is controlled by a potentiometer and a controller (11) for a measuring device.

摘要： A coordinate measuring machine carries a modular touch trigger probe 100, via an adaptor 200, on its movable arm 10. The probe 100 consists of a retaining module 102 which is mounted to the adaptor 200, and a stylus module 104 which is magnetically connected to the retaining module 102 in a manner which enables the exchange of one stylus module 104 for another. The adaptor consists of a pair of coupling members 202,204 which are urged into mutual engagement by magnets 212. Automatic exchange of stylus modules occurs by using movement of the arm 10 to disengage a stylus module 104 from the retaining module 102. Similarly, the exchange of one probe for another is carried out by using movement of the arm 10 to disengage the lower coupling member 204 from the upper coupling member 202. Because magnetic attraction between the coupling members 202,204 is necessarily greater than the attraction between retaining and stylus modules 102,104, lower coupling member 204 has three levers 222, operable by downward relative movement of a release ring 220, which occurs during uncoupling. The levers 222 provide the mechanical advantage necessary to enable movement of the arm 10 to overcome the relatively large magnetic attraction force between coupling members 202,204.
