摘要： This invention concerns a method of generating a spatial map of sensor data collected during additive manufacturing, in which a plurality of layers of powder are selectively melted with an energy beam to form an object. The method comprises receiving sensor data collected during additive manufacturing of an object, the sensor data comprising sensor values, the sensor values captured for different coordinate locations of the energy beam during the additive manufacturing of the object, and generating cell values for a corresponding cell-based spatial mapping of the sensor data. Each of the cell values is determined from a respective plurality of the sensor values extending over an area/volume comparable to an extent of the melt pool or the energy beam spot.

摘要： A method is described for assessing the beam profile of a light beam (12) of a non-contact tool setting apparatus. The non-contact tool setting apparatus comprises a transmitter (10) for emitting the light beam and a receiver (14) for receiving the light beam (12). The receiver (14) generates a beam intensity signal describing the intensity of received light. The non-contact tool setting apparatus is mounted to a machine tool having a spindle that is moveable relative to the non-contact tool setting apparatus. The method comprises loading an object having an edge into the spindle of the machine tool and using the machine tool to move the spindle relative to the non-contact tool setting apparatus so that the edge of the object passes through the light beam (12). The beam profile of the light beam (12) is then determined using the beam intensity signal generated at a plurality of positions during the step (ii) of moving the edge of the object through the light beam (12).

摘要： A method for tool measurement using a non-contact tool setting apparatus mounted to a machine tool. The non-contact tool setting apparatus comprises a transmitter (10) for emitting a light beam (12;80) having a beam width and a receiver (14) for receiving the light beam (12). The receiver (14) generates a beam intensity signal describing the intensity of received light. The method is for measuring a tool (84) comprising a tool feature having a nominal tool diameter less than the beam width such that fully inserting the tool (84) feature into the light beam (80) would only partially occlude the light beam (80). The method comprises moving the tool feature through the light beam (12;80) thereby causing a change in the beam intensity signal and generating a trigger signal when the beam intensity signal crosses a trigger threshold. A size of the tool feature (84) is generated using the trigger signal generated. The method also comprises a step of applying a tool size correction (e.g. a change to the trigger threshold, trigger delay etc) that accounts for the nominal tool diameter of the tool feature (84) being less than the beam width by adjusting the trigger threshold so that the amount of obscuration required for a trigger signal is reduced for smaller tool diameters.

摘要： 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.

摘要： Metrology apparatus is described that includes a first structure rotatably connected to a second structure by a bearing arrangement. The bearing arrangement includes at least a first friction bearing including parts in sliding contact during rotation of the first structure relative to the second structure. The apparatus includes at least one magnet that relieves the load on the first friction bearing. Multiple magnets, provided in an attracting or repelling arrangement, may be used. The metrology apparatus may include an articulating probe head for a coordinate positioning apparatus.

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.
