Abstract: A protection member for an optical measurement device, such as a break-beam tool setting device for a machine tool. The protection member includes a conduit through which light and air can pass. The conduit is configured such that, in use, a beam of light is passed through the conduit along an optical axis and a stream of air is guided out of the conduit along an airflow axis. The optical axis is non-parallel to the airflow axis and the conduit has a varying cross-sectional profile along the airflow axis. Improved measurement repeatability is provided.

Abstract: A method of operating a position encoder apparatus, including a scale having features defining position information and a readhead for reading the scale. The method includes: calculating extrapolated position information from at least one previous reading of the scale; comparing an extrapolated position with a position calculated from a reading of the scale to determine any discrepancy between them; using the extrapolated position information whether or not there is a discrepancy; and maintaining a record of any discrepancies.

Abstract: A method builds a workpiece using an additive manufacturing process, wherein the workpiece is built up by consolidating material in a layer-by-layer manner. The method includes receiving an initial geometric model defining surface geometry of the workpiece, determining workpiece slices to be consolidated as layers of the workpiece during the additive manufacturing process from the initial geometric model, determining adjusted positions of the workpiece slices adjusted from initial positions of the workpiece slices as determined from the initial geometric model, the determination of the adjusted positions based upon warping of the workpiece expected to occur during or after the additive manufacturing process, and building the workpiece using the additive manufacturing process, wherein the workpiece slices are formed in the adjusted positions.

Abstract: A sealed encoder module for mounting onto a machine so as to measure relative displacement of first and second parts of the machine. The sealed encoder module can comprise, a scale, a readhead comprising a scale signal receiver, and an integral protective housing which encapsulates at least the scale and said scale signal receiver. The sealed encoder module can be configured to determine and output diagnostic information regarding a scale signal detected by the readhead.

Abstract: An additive manufacturing apparatus including a scanner for directing a laser beam on to layers of flowable material to selectively solidify the material to form an object in a layer-by-layer manner. The scanner includes an optical component operable under the control of a first actuator to reflect the laser beam over a first range of angles in a first dimension and the or a further optical component operable under the control of a second actuator to reflect the laser beam over a second range of angles in the first dimension, wherein the second actuator provides a faster dynamic response but a smaller range of movement of the laser beam than the first actuator.

Abstract: A powder bed fusion additive manufacturing method includes forming layers of powder of a powder bed and exposing the layers to one or more energy beams to melt the powder to form an object. The exposure of each layer to the or each energy beam forms melt pools in a conduction or transition mode with an exposure distance between adjacent exposures within the layer being 40% to 60% of a width of the melt pools generated by the exposures and an offset of exposures between successively melted layers in a direction in which the exposure distance is measured being 40% to 60% of the exposure distance.

Abstract: A method controls an additive manufacturing apparatus, in which an object is built by consolidating material in a layer-by-layer manner. The method includes receiving commands to be executed by the additive manufacturing apparatus to cause the additive manufacturing apparatus to carry out a build of an object, wherein each command includes an identifier identifying a time during the build at which the command is to be executed, and executing each command on the additive manufacturing apparatus in accordance with the time identified by the associated identifier. Further, an apparatus and a data carrier carry out the method.

Abstract: 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.
