摘要： Method for cutting a planar and/or metal workpiece along a predefined cutting contour using a laser beam and a cutting gas emitted from a nozzle, wherein the laser beam makes a recess in the workpiece so as to form a recess hole (on the cutting contour or at least partly close to the cutting contour. At least two machining parameters are continuously modified during formation of the recess hole, and/or at least one machining parameter is continuously modified on a switch path between the recess hole and an endpoint lying on the cutting contour.

摘要： A removably attached coupling assembly can he used to he attached to a laser focus optic assembly of a liquid jet guided laser system. The coupling assembly can include a coupling body, a window assembly, and a nozzle assembly. The coupling assembly thus can allow the independent and separate servicing of the window and the nozzle. For example, to service the window, the coupling assembly can be first detached from the laser focus optic assembly, exposing the top portion of the coupling assembly. The window assembly then can be detached from the coupling assembly. The window can be removed from the window assembly for servicing, such as being repaired or replaced.

摘要： A method forming a metallic structure having two or more portions is provided. The method can include providing a first layer of metal-forming material and then applying energy of a first power level to a first area of the first layer of metal-forming material to form a first portion of the metallic structure having a first density. Energy of a second power level can then be applied to a second area of the first layer of metal-forming material to form a second portion of the metallic structure having a second density. A second layer of the metal-forming material can be applied on top of the first portion and the second portion. The energy of the first power level can be applied to a first area of the second layer of metal-forming material and the energy of the second power level can be applied to a second area of the second layer to form the metallic structure.

摘要： A laser processing head (100) comprises a first-level nozzle (110) and a second-level nozzle (120) that communicate with each other, wherein the second-level nozzle (120) is arranged downstream of the first-level nozzle (110); an inner diameter of the second-level nozzle (120) gradually decreases in a laser transmission direction, and minimum inner diameter of the first-level nozzle (110) is larger than the inner diameter of a tail end of the second-level nozzle (120). The laser processing head (100) solves the contradiction between high energy density laser and the system reliability through gradual coupling. Also provided are an application of the laser processing head, a laser processing system and a laser processing method.

摘要： This specification discloses an optical processing head including a light guide portion that guides, to a process surface, a ray for processing. The light guide portion is further configured to guide, to the process surface, a ray for inspection different in wavelength from the ray for processing. The optical processing head further includes an inspection portion that inspects the state of the process surface based on reflected light of the ray for inspection reflected by the process surface. With the optical processing head, the state of the process surface can be easily inspected even during optical processing.
