摘要： Disclosed is a method of communicating information to a measurement probe mounted on a coordinate positioning machine. The method comprises encoding the information as one or more of a plurality of characteristic movements of the probe, controlling the machine to impart the movement(s) to the probe, detecting the movement(s) at the probe, and decoding the information at the probe from the detected movement(s). A measurement probe for use in such a method is also disclosed. The measurement probe is mountable to the machine and comprises at least one movement sensor for sensing movement imparted to the measurement probe by the machine, and a controller for determining whether the sensed movement comprises one or more of the plurality of characteristic movements of the probe and for performing an operation at or controlling operation of the probe in dependence on the determination.

摘要： A method and apparatus for determining an alignment of an optical scanner (106a, 106c) for directing an electromagnetic beam to locations within a scan field. The method may comprise locating a reference element (113) within the scan field of the optical scanner (106a, 106c) and controlling the optical scanner (106a, 106c) to cause the electromagnetic beam to be directed to a plurality of different points in the scan field, including at least one point on the reference element (113). Reflected electromagnetic radiation is detected. The method may comprise determining when the electromagnetic beam is directed to a reference position in the scan field given by the reference element (113) from a comparison of an intensity of the detected electromagnetic radiation for the different points and determining a corresponding demand signal that causes the optical scanner (106a, 106c) to direct the electromagnetic beam to the reference position.

摘要： An additive manufacturing method wherein an object is formed by selectively solidifying layers of powder with at least one energy beam. The method comprises forming the object from a nickel-based superalloy, wherein exposure parameters and an exposure pattern for the at least one energy beam result in the object having a directionally solidified microstructure with columnar grains aligned with a build direction, perpendicular to the layers. A composition of the nickel-based alloy by weight % may comprise: 9.3-9.7W, 9.0-9.5Co, 7.5-8.5Cr, 5.4-5.7Al, 3.1-3.3Ta, 1.4-1.6Hf, 0.6-0.9Ti, Mo 0.4-0.6, 007-.015Zr, 0.01-0.02B with a carbon concentration of around 0.07-0.09wt% and a balance of Ni.

摘要： A calibration device for a co-ordinate positioning machine, such as a machine tool, is described. The device (200) comprises a base (30; 130; 202), a calibration artefact (34;134), and a deflection mechanism (32) that attaches the calibration artefact (34;134) to the base (30;130; 202) and allows the calibration artefact (34;134) to be moved relative to the base (30;130; 202) by application of an external force. The device further comprises a releasable lock that, when locked, immobilises the calibration artefact (34;134) relative to the base (30; 130; 202).

摘要： A coordinate positioning arm (A) is disclosed that comprises: a base end (B) and a head end (H); a drive frame (D) for moving the head end (H) relative to the base end (B); and a metrology frame (M) for measuring a position and orientation of the head end (H) relative to the base end (B). The drive frame (D) comprises a plurality of drive axes (D1, D2, D3) arranged in series between the base end (B) and the head end (H). The metrology frame (M) comprises a plurality of metrology axes (R1, R2, R3, L4, R5, R6) arranged in series between the base end (B) and the head end (H). Advantageously, the metrology frame (M) is adapted and arranged to be substantially separate and/or independent from the drive frame (D). The separation and/or independence between the metrology frame (M) and drive frame (D) may be achieved for example by supporting the metrology frame (M) substantially only at the base end (B) and head end (H) and by providing the metrology frame (M) with sufficient degrees of freedom (via the metrology axes) to avoid creating an additional constraint between the metrology frame (M) and the drive frame (D). This avoids creating movements within the metrology frame (M), due to non-ideal movements and/or behaviours associated with the drive frame (D) and/or metrology frame (M), that are not allowed by any combination of one or more of the metrology axes (R1, R2, R3, L4, R5, R6), and hence not measured, and this provides a more accurate coordinate positioning arm (A).
