摘要： This invention concerns a laser solidification apparatus for building objects by layerwise solidification of powder material. The apparatus including a build chamber containing a build platform, a device for depositing layers of powder material on to the build platform, an optical unit for directing a laser beam to selectively solidify areas of each powder layer and a spectrometer for detecting characteristic radiation emitted by plasma formed during solidification of the powder by the laser beam. The invention also relates to a spectrometer for detecting characteristic radiation generated by interaction of the metal with the or a further laser beam. The spectra recorded using the spectrometer may be used for feedback control during the solidification process.

摘要： A method for removing noise from spectral data recorded using a spectrometer. The method includes normalising spectral data to generate normalised spectral data and applying a machine learning model to the normalised spectral data. The machine learning model is trained to remove noise from spectral data using normalised training data, wherein the spectral data is normalised based on a different scaling to the normalisation of the training data.

摘要： A coordinate positioning machine includes a plurality of drive axes, each being a rotary or linear drive axis, for positioning a platform within a working volume of the machine, and a separate linear counterbalance axis for counterbalancing the platform. With this arrangement the counterbalance axis can be substantially invariant to changes in orientation of the drive axes and can be counterbalanced by a simple counterweight. Also, an arrangement wherein the counterbalance axes and force generator are arranged so horizontal movement of the platform causes substantially no net movement of and/or no work to be done on the generator. Also, an arrangement wherein a series of counterbalance axes has at least one rotary counterbalance axis, and the generator is arranged behind or at a predetermined distance from the counterbalance axis. Also, an arrangement having a series of counterbalance axes with at most one rotary counterbalance axis between the generator and ground.

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 frequency hopping radio communications module for a measurement system, including a measurement probe and an interface for a machine tool. The communications module is configured to transmit and/or receive radio signals using at least ten frequency channels and can operate in at least a metrology mode for communicating measurement data and a standby mode. Operation in the standby mode includes hopping between fewer frequency channels than operation in the metrology mode. In particular, operation in standby mode includes hopping between three of the at least ten frequency channels in accordance with a second hopping pattern, the three frequency channels being from different thirds of the frequency band. This allows faster frequency hopping synchronisation to be achieved and improves battery life.

摘要： A method of communicating information to a measurement probe mounted on a coordinate positioning machine includes 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 mountable to the machine and includes 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 includes 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 of calibrating a coordinate positioning machine is described. The machine is controlled into a pivot pose in which a target point associated with a moveable part of the machine and a pivot point associated with a fixed part of the machine are separated from one another by a known separation. An error value for that pose is determined based on the known separation and a separation expected for that pose from the existing model parameters of the machine. The machine is controlled into a plurality of different target poses, and for each target pose a separation between the target point and the pivot point is measured and an error value for that pose is determined based on the measured separation and a separation expected for that pose from the existing model parameters.

摘要： A selective solidification apparatus includes a build chamber, a build platform lowerable in the build chamber, a wiper for spreading powder material across the build platform to form successive powder layers of a powder bed, an energy beam unit for generating an energy beam for consolidating the powder material, a scanner for directing and focussing the energy beam onto each powder layer and a processor for controlling the scanner. The processor is arranged to control the scanner to scan the energy beam across the powder bed to consolidate powder material either side of the wiper when the wiper is moving across the powder bed and to scan the energy beam across at least one of the powder layers during two or more strokes of the wiper across the powder bed.

摘要： A powder bed fusion apparatus for building an object, including a processing chamber having a processing chamber aperture, scanner arranged to direct an energy beam to locations in a plane of the aperture and debuilding chamber having a debuilding chamber aperture. The apparatus includes a build chamber including a build sleeve and platform movable therein for supporting powder, the platform including a seal for engaging with the sleeve walls to prevent flow of powder past the platform; and at least one drive mechanism for driving movement of the platform. A translation mechanism moves the chamber between a building position, wherein the sleeve aligns with the processing aperture so an energy beam can be delivered to consolidate powder to build the object, and debuilding position, wherein the sleeve aligns with the debuilding aperture so the object and powder can be inserted into the debuilding chamber through movement of the platform.
