  • Laser cutting nozzle for a laser machining unit and method for operating such a laser machining unit
    Patent number: 12017303
    Abstract: A laser cutting nozzle for a laser machining unit is described, the nozzle including a passage for the laser beam and cutting gas. The passage extends between a nozzle inlet and a nozzle mouth along a passage longitudinal axis. The passage comprises a convergence portion and a divergence portion. In the entire divergence portion, the wall of the passage forms an angle of inclination relative to the passage longitudinal axis of at most 5°. In addition, the length of the divergence portion is less than 5 times the diameter of the constriction.
    Type: Grant
    Filed: September 15, 2022
    Date of Patent: June 25, 2024

  • METHODS FOR THE AUTOMATED DETERMINATION OF THE INFLUENCE OF A LASER PROCESSING PARAMETER ON A LASER PROCESSING OPERATION, LASER PROCESSING MACHINE, AND COMPUTER PROGRAM PRODUCT
    Publication number: 20210354232
    Abstract: Methods, machines, and computer program products are disclosed for determining the influence of a laser processing parameter on a laser processing operation by means of a laser beam are described. The methods include conducting linear laser processing operations with different values of the laser processing parameter, the speed of advance of the laser beam, respectively, being increased in the laser processing operations at least to such an extent that a processing interruption occurs; and determining a relationship between the processing lengths, the associated processing times, or the associated interruption speeds of the laser processing operations and the laser processing parameter using the measured processing lengths, the associated processing times, or the associated interruption speeds of the laser processing operations.
