摘要： A surface finish stylus is described that includes an elongate stylus shaft and a contact element protruding from the elongate shaft for contacting a surface to be measured. The contact element is deformable and the stylus shaft includes a clamp for retaining the contact element, the contact element being deformed by the clamp. The contact element may comprise a metal, such as chromium steel or nitinol. The contact element includes one or more regions of weakness to cause a required deformation when retained by the clamp. The surface finish stylus may be used with a surface finish measurement probe or the like.

摘要： A method for measuring gaps between material layers include inserting a probe tip within a through-hole defined in a structural component. The probe tip is arranged at the end of a probe assembly attached to articulated arm coordinate measuring machine (AACMM). The method further includes contacting the probe tip with a hole surface of the through-hole. The method further includes translating the probe tip along the hole surface in a direction parallel to an axis through the through-hole. The probe tip passes over a gap along the through-hole. The method further includes measuring a radial position of the probe tip during the translation along the hole surface and across the gap including a deflection of radial position of the probe tip as the probe tip crosses the gap. The method further includes calculating a gap size of the gap based on the deflection and a size of the probe tip.

摘要： A scanning probe for a coordinate measurement machine includes a stylus suspension module, a stylus position detection module, a disruptor configuration, and a signal processing and control circuitry module. The stylus position detection module includes a sensor configuration, which comprises various coils, and a shield configuration that is located around the sensor configuration and comprises electrically conductive material for shielding the sensor configuration. The stylus position detection module is mounted to the stylus suspension module utilizing a module mounting configuration, which enables the relative position of the sensor configuration to be adjusted for alignment during the assembly of the scanning probe.

摘要： A surface sensing device is mounted on an articulating probe head of a coordinate measuring machine. The device includes an elongate probe holder which is rotatable about an axis. An elongate sensing module includes a surface finish or surface roughness probe with a stylus tip. This is connected to the probe holder via an adjustable knuckle joint. To determine the geometry of the surface sensing device, including the tip normal and drag vector of the stylus tip, the orientations of the probe holder and the sensing module are determined by probing points which are spaced along their lengths, using a separate probe.

摘要： An error identification method includes: installing a calibrator including a sphere row A and a sphere row B in which a plurality of spheres are linearly aligned in a direction perpendicular to the sphere row A on a table such that the sphere row A and the sphere row B are approximately parallel to respective two of the translational axes and measuring positions of a plurality of spheres of the sphere row A and the sphere row B using a position measurement sensor tool; rotating the calibrator to a plurality of angles around a normal direction on the upper surface of the table to install on the table and measuring each position of the plurality of spheres of the sphere row A and the sphere row B; and identifying an error of the translational axis based on measured values in the installing and the rotating.

摘要： An abnormality determination apparatus includes a data acquisition part that acquires position data indicating a plurality of positions to be measured of a standard gage used in a coordinate measuring apparatus, in association with apparatus identification information for identifying the coordinate measuring apparatus, a generation part that generates distance data indicating a distance to be measured that is a distance between the plurality of positions to be measured indicated by the position data, a storage that stores an appropriate range in which the distance data is determined to be appropriate, and a determination part that determines whether there is an abnormality in the coordinate measuring apparatus on the basis of whether or not the distance to be measured indicated by the distance data is included in the appropriate range, and outputs a determination result in association with the apparatus identification information.

摘要： An ultrasound probe is described that comprises a transducer for transmitting and receiving ultrasound. The probe also includes a coupling element, such as a spherical ball of self-lubricating or hydrogel material, for contacting and acoustically coupling to an object to be inspected. The ultrasound probe also includes an analyser that is arranged to analyse the ultrasound signal received by the transducer and thereby determine if there is contact between the coupling element, and the surface of an object. The probe can thus be used for internal (ultrasound) inspection of objects as well as measuring the position of points on the surface of the object. The probe may be mountable to a coordinate measuring machine or other moveable platforms.
