  • Method for determining the reference focal position of a laser beam
    Patent number: 11065721
    Abstract: A method for determining a reference focal position of a laser beam for processing a plate-like member, the method comprising producing at least two incisions in the plate-like member with the laser beam set at different focal positions, irradiating the plate-like member with the laser beam, detecting edges of the incisions by measuring one or more parameters relating to the irradiation of the plate-like member, and establishing a width of the at least two incisions using the detected one or more parameters.
    Type: Grant

  • Piercing workpieces by a laser beam and an associated laser processing machine
    Patent number: 11045908
    Abstract: This disclosure relates to methods and apparatuses for piercing workpieces at a piercing point using a laser beam, which exits from a laser processing nozzle with a process gas, whereby a bulge is formed on the workpiece surface around the piercing point during the piercing. A distance between the laser processing nozzle and the bulge is determined during the piercing and at least one piercing parameter is changed in dependence on the distance determined.

  • Determining a material type and/or a surface condition of a workpiece
    Patent number: 10115190
    Abstract: This disclosure relates to methods and apparatuses for determining a material type and/or a surface condition of a workpiece. A surface of the workpiece is illuminated with illuminating radiation. At least one image of the illuminated surface is recorded. The material type and/or the surface condition of the workpiece is determined on the basis of a statistical analysis of the at least one image converted into a spatial frequency domain.

  • Method and apparatus for detecting a condition of an optical element
    Patent number: 7705292
    Abstract: A condition or detecting a change in the condition of an optical element of a laser arrangement is detected. An ultrasonic signal is coupled into an optical element such that the ultrasonic signal travels along a path within the optical element, and a transit time or a change in transit time for the ultrasonic signal to travel along the path within the optical element is detected.
