  • Patent number: 12370627
    Abstract: The laser machining apparatus of the present invention is configured to analyze and adjust a cutting order of opening forming regions in order to prevent a scrap rising from interfering with a laser head by determining a first opening forming region and a second opening forming region based on interfering conditions of the scrap rising with the laser head and processing the second opening forming region prior to the processing of the first opening forming region.

  • Publication number: 20250196271
    Abstract: A laser processing path laying-out method includes laying out, to a part of a notch of nesting data, as a partial processing path in a notch formation processing path, an open path for cutting to an inner side of a product, excluding a line segment of the part of the notch in an outer peripheral end portion of the product. The laser processing path laying-out method further includes laying out an outer peripheral path obtained by coupling a first outer peripheral processing path for cutting a line segment of the part of the notch in the outer peripheral end portion, which is a remaining partial processing path in the notch formation processing path, and a second outer peripheral processing path for cutting at least a part of a line segment other than the part of the notch in the outer peripheral end portion.

  • Patent number: 12059750
    Abstract: An NC device controls a processing machine body so as to form an opening by cutting the periphery of an opening forming area in a material. In a case where a skid interferes with the opening forming area and the interfering skid is positioned within a margin from a first gravity center of the opening forming area in an alignment direction of the skid, the NC device controls the processing machine body so as to cut the opening forming area with a dividing line set at a position that is apart by a predetermined distance from the skid in the alignment direction of the skid. The predetermined distance is a distance in which the material is not welded to the skid, and is a distance in which a second gravity center of a scrap interfering with the skid is positioned at a distance longer than the margin from the skid.

  • Publication number: 20230398637
    Abstract: At least one dividing line formed of a straight line is set in a hole forming region surrounded by a hole processing line. It is determined whether or not a smaller one of connection angles at a first connecting point at which the dividing line is connected to a hole processing line is smaller than a predetermined angle. When the connection angle is smaller than the predetermined angle, a line segment between an auxiliary line and the hole processing line is replaced with corrected dividing line. A corrected connection angle at a second connecting point at which the corrected dividing line is connected to the hole processing line is set so as to be larger than a connection angle before correction.

  • Publication number: 20220143749
    Abstract: An NC device 20 determines, in a case where a size of an opening forming region in a predetermined direction is smaller than a predetermined maximum value, that the opening forming region is a first opening forming region, and determines, in a case where the size of the opening forming region in the predetermined direction is larger than a predetermined minimum value, that the opening forming region is an opening forming region where a scrap interfering with a laser head 16 is formed. In a case where the size of the opening forming region in the predetermined direction is smaller than the predetermined maximum value and larger than the predetermined minimum value, the device determines that the opening forming region in an interference width added region obtaining by adding a predetermined interference width to the opening forming region is a second opening forming region, and processes the second opening forming region prior to processing of the first opening forming region.
