In some aspects, methods for measuring a level of usage of one or more replaceable consumable components within a material processing system can include detecting a type of consumable component in use within a processing device of the material processing system; determining, using a computing system, if the type of consumable component in use is a specific type of consumable component; and determining, using the computing system, a usage ratio of the specific type of consumable component used relative to other types of consumable components used within the processing device during a cumulative time period of use of the material processing system.

A fixture assembly for supporting a plurality of blanks during a welding operation. The fixture assembly includes a frame. A plurality of electromagnets are positioned on the frame for supporting the blanks and for drawing the blanks toward the electromagnets to secure the blanks into a desired position. A plurality of intensifiers are moveably connected to the frame for selectively overlying the top face of one of the electromagnets for clamping the blank against the electromagnet to intensify a magnetic force provided by the electromagnet. A plurality of electromagnet adjusters are each coupled with the frame and with at least one of the electromagnets for moving the electromagnets relative to the frame. A plurality of adjusting pins are each connected to the frame and moveable relative to the frame for adjusting a position of the blanks.

A method is described for decontaminating room air by means of a tabletop apparatus (10) (or with dedicated stand) for the processing of metal costume jewelry/goldsmiths or dental prostheses through a LASER beam, wherein a source of UV and/or UV-C radiation irradiates a forced flow (F) of ambient air before it comes out of a casing of the apparatus.

Described are a method and laser plotter for processing a job for cutting, engraving, marking and/or lettering a flat workpiece having at least one housing with a processing chamber formed for positioning a workpiece. The chamber has at least one irradiation source in the form of a laser and a control unit for controlling the sledge, which may be operated via a belt drive and has a focusing unit arranged movably thereon. Between the sledge and a processing surface of the processing chamber, an extraction bar is arranged for extracting the exhaust gases or vapors, respectively, produced by a laser beam during the processing of the workpiece. One or more extraction openings of the extraction bar are arranged or aligned, respectively, parallel to the processing surface for generating a horizontal extraction flow.

A control device that executes machining to cut a workpiece into a part and a remaining material; a detection unit that determines, as a time-series signal, a result of observing in time series a state of the workpiece; a machining state evaluation unit that determines, as evaluation information, a result of evaluation on a state of the machining for each of sections obtained by dividing the machining path, based on the time-series signal; an evaluation information storage unit that stores contour line evaluation information in which a contour line is associated with the evaluation information; and a sorting operation determination unit that determines a sorting control command for controlling sorting operation in which the part is taken out from a position where the workpiece is machined and moved to a target position, based on the contour line evaluation information; are provided.

A deposition head for a three-dimensional printer with at least one pay-out device which comprises several wire spools, each spool having a wire to be deposited simultaneously with the other wires, a drive system having a drive roller with several grooves, one for each wire to be deposited simultaneously, a wire guide which has a first end, a second end close to a deposition zone during operation, and also a passage hole opening out at each of the first and second ends, the passage hole having several passage sections at the second end, one for each wire to be deposited simultaneously, and each passage section having a section substantially identical to the section of the wire to be guided.

A laser processing system that can effectively blow out a material of a workpiece melted by a laser beam by effectively utilizing an assist gas emitted from a nozzle. The laser processing system comprising a nozzle including an emission opening configured to emit a jet of an assist gas along an optical axis of a laser beam, the nozzle being configured to form a maximum point of velocity of the jet at a position away from the emission opening; a measuring instrument configured to measure a sound generated by the jet impinging on an object; and a position acquisition section configured to acquire information representing the position of the maximum point based on output data of the measuring instrument.

A laser processing system capable of reliably determining an abnormality in a jet during laser process. The laser processing system comprises a nozzle including an emission opening configured to emit a jet of an assist gas along an optical axis of a laser beam, the nozzle being configured to form a maximum point of velocity of the jet at a position away from the emission opening; a measuring instrument configured to measure any of the velocity of the jet and a sound generated by the jet impinging on a workpiece; and an abnormality determination section configured to determine whether or not output data of the measuring instrument is different from reference data.

A system and method of monitoring a powder-bed additive manufacturing process is provided where a layer of additive powder is fused using an energy source and electromagnetic emission signals are measured by a melt pool monitoring system to monitor the print process. The measured emission signals are analyzed to identify outlier emissions and clusters of outliers are identified by assessing the spatial proximity of the outlier emissions, e.g., using clustering algorithms, spatial control charts, etc. An alert may be provided or a process adjustment may be made when a cluster is identified or when a magnitude of a cluster exceeds a predetermined cluster threshold.
