    Abstract: Sheet metal pieces intended to be welded can be made with weld notches located along one or more edges. A weld notch is characterized by the absence of certain material constituents so that they do not unacceptably contaminate nearby welds. The weld notch can be created by first forming an ablation trench along the sheet metal piece, then separating the sheet metal piece along the formed ablation trench into two separate pieces, at least one of which includes a newly formed and weldable edge.

  • Patent number: 10799982
    Abstract: To provide a nozzle for laser processing head capable of reliably drilling a small hole when drilling of the workpiece is performed by using a laser machine. A nozzle includes: a nozzle tip body that irradiates a workpiece with a laser beam; a charge port formed in the nozzle tip body; an exhaust port formed in the nozzle tip body so as to oppose to the charge port; and an elastic member that is provided in a tip end of the nozzle tip body and contacts with the workpiece while elastically extending and contracting in the axial center direction of the nozzle tip body. The nozzle supplies gas to the inside of the nozzle tip body along a gas flow path extending from the charge port to the exhaust port in a form of crossing across the laser beam in the nozzle tip body, to generate a negative pressure in the vicinity of an opening part of a tip end of the nozzle tip body. The elastic member contacts with the workpiece and improves the degree of enclosure of the nozzle tip body by the workpiece.

  • Patent number: 10796959
    Abstract: A laser beam machining method and a laser beam machining device capable of cutting a work without producing a fusing and a cracking out of a predetermined cutting line on the surface of the work, wherein at pulse laser beam is radiated on the predetermined cut line on the surface of the work under the conditions causing a multiple photon absorption and with a condensed point aligned to the inside of the work, and a modified area is formed inside the work along the predetermined determined cut line by moving the condensed point along the predetermined cut line, whereby the work can be cut with a rather small force by cracking the work along the predetermined cut line starting from the modified area and, because the pulse laser beam radiated is not almost absorbed onto the surface of the work, the surface is not fused even if the modified area is formed.

  • Patent number: 10769718
    Abstract: Machine learning-based approaches are used to create instances or visualizations of content appearing within an object in an image. For example, a user may submit a request for a preview or visualization of content within an object or other media such as a glass crystal. A trained model can process the content to generate adjustment data or other data that can be used to control image blending operations. The adjustment data can be applied to the pixel values of the content to modify the content in order to enable a visualization of the content within an object. The image portion can be modified such that the object appears to “blend” with and appear within the object. Image transformation techniques can be used to project the modified content onto a representation of an object. Thereafter, a visualization or preview of the content within the representation of the object can be presented.

  • Patent number: 10695869
    Abstract: A process to produce a workpiece surface or a groove inner surface on a rod-shaped, especially cylindrical workpiece. From the workpiece, a rotary tool is supposed to be produced. The material removal is done using laser beam pulses, which are directed through a deflection device onto points of incidence within a pulse area with a specified outside contour on the workpiece. Multiple machine axis drives position the workpiece and the deflection device relative to one another so that the pulse area is oriented essentially at right angles to the emission direction of the laser beam pulses and at right angles to the section of the tool surface that has already been produced and that borders the pulse area. While the material is being removed, the at least one machine axis drive moves the pulse area relative to the workpiece along a specified path of motion while maintaining the orientation.
