A laser crafting apparatus for directing electromagnetic radiation toward a workpiece may include various features. For example, the laser crafting apparatus may include a material support tray that is removably supported within an internal volume of the laser crafting apparatus. Further, the apparatus may include pre-filter disposed in a ventilation pathway between a workspace region of the internal volume and an extractor fan. The laser crafting apparatus may include a laser carriage assembly that houses a laser module and the assembly may include a lens tray detachably coupled to the support structure of the laser carriage assembly. In various embodiments, the laser crafting apparatus includes a lid having a radiation attenuation layer and a fire suppression layer.

A laser machining device having a surface plate upon which a material to be machined is placed, a rail, a saddle, a garter, a horizontal carriage, and a laser nozzle. On it is attached: a machining trolley that causes the saddle to travel along rail, causes the horizontal carriage to travel horizontally along garter, irradiates laser light from laser nozzle towards a material to be machined, and cuts or welds the material. A cover is provided that covers substantially the entire surface of machining trolley and has an upper surface cover, a laser nozzle-side cover, a garter-side cover, and a side surface body. On a lower end side of the laser nozzle-side cover and the garter-side cover, there is a flexible light-blocking member for preventing laser light from leaking from a gap between the lower end section and the upper surface of the surface plate.

A three-dimensional laser cutter can be disposed in a machining room. The machining room includes a ceiling and a plate member. The ceiling is provided with a suction port connected to a suction device. The plate member is disposed below the ceiling with a gap therebetween. The plate member forms a space with the ceiling.

A laser processing unit includes a workpiece loading station, and a laser workstation having a laser robot that performs a laser operation. A flexible endless loop extends from the loading station through the workstation for delivering a workpiece from the loading station to the workstation. A first stationary wall section separates the workstation from the loading station. A second stationary wall section is offset from the first stationary wall section. A first movable door is configured to form a laser light-tight seal with the first stationary wall section. A second movable door configured to form a laser light-tight seal with the second stationary wall section. A seal projection is attached to the flexible endless loop. The seal projection forms a laser light-tight seal with the first movable door when the workpiece is located in the loading station and forms a laser light-tight seal with the second movable door when the workpiece is located in the workstation.

A laser machining head includes a protection window disposed inclined with respect to an optical axis of a laser beam, an inflow port disposed downstream of the protection window and configured to allow a gas to flow in, and a flow dividing projection configured to divide the gas into a first laminar flow flowing along parallel to a surface of the protection window and a second laminar flow flowing toward a workpiece. The flow dividing projection is disposed in a position opposing to the inflow port with the optical axis of the laser beam as the center.

A laser machining head has a function of rectifying an assist gas and includes a protection window, a nozzle configured to blow the assist gas over a workpiece, a chamber defining a space between the protection window and the nozzle, an inflow port disposed in a chamber and configured to allow the assist gas to flow in, and a flow dividing projection disposed at a position opposing to the inflow port and configured to divide the assist gas from the inflow port into a first flow and a second flow flowing along a circumferential direction around an optical axis of a laser beam.

A laser system includes a controller, a laser source, a laser scanner, and a laser containment apparatus. The laser containment apparatus includes a mounting structure for the laser scanner, a shroud assembly coupled to the mounting structure, and a seal interface coupled to the shroud assembly at an opposite end from the laser scanner. The shroud assembly surrounds a working volume of the laser scanner and includes a vacuum port connected to a vacuum source and a purge port that guides purge gas from a purge gas source toward the laser scanner. A distal end of the seal interface is formed of a pliable material that compresses to seal the shroud assembly to a target surface of a workpiece upon establishment of a negative pressure differential between a vacuum pressure inside the shroud assembly and ambient atmospheric pressure.

In some examples, systems and techniques for repairing or otherwise forming a blade of a bladed disk. In one example, a method including positioning a shield member around a perimeter of a partial blade extending from a rotor disk of a bladed disk, the shield member being positioned adjacent to a build surface of the partial blade; and depositing, with the shield member around the perimeter of the partial blade, a material on the build surface using an additive manufacturing technique to form a repaired portion on the build surface of the partial blade.

A debris control apparatus is provided for selective assembly and disassembly with a cutting tool. The debris control apparatus includes a debris control enclosure and a mounting assembly for mounting the enclosure to the cutting tool. The enclosure comprises a vacuum opening assembled and in fluid communication with a vacuum conduit, the vacuum conduit connected to a vacuum source, for extracting the debris from the enclosure. The enclosure and vacuum conduit may be sized, shaped, and contoured to reduce recirculation of debris within the enclosure.

A laser processing device includes a beam splitter disposed between a focusing lens and a protective window, a return light measurement unit configured to measure intensity distribution of a return light reflected from a workpiece and returning to an external optical system via the beam splitter, a storage unit configured to store at least one of normal pattern data representing the intensity distribution of the return light when the protective window is in normal condition and abnormal pattern data representing the intensity distribution of the return light when the protective window is contaminated, a processing unit configured to perform a process of detecting contamination of the protective window during laser processing based on measurement data about the return light and at least one of the normal pattern data and the abnormal pattern data, and a warning unit configured to warn of contamination of the protective window in accordance with the process.
