  • LASER PROCESSING METHOD AND LASER PROCESSING MACHINE
    Publication number: 20160297033
    Abstract: In a laser processing method for carrying out hole-forming on a plate-shaped workpiece, [A] a hole is formed by laser-cutting the workpiece along an outline of the hole to be formed, [B] a laser processing head is moved with respect to the workpiece after forming the hole, and [C] a cutout piece inside the outline of the hole is dropped off by moving the laser processing head while jetting assist gas from the laser processing head to the cutout piece inside the outline. According to the laser processing method, the cutout piece generated when carrying out hole-forming by laser processing can be prevented from getting stuck in a hole.

    Patent number: 9250390
    Abstract: An optical delivery waveguide for a material laser processing system includes a small lens at an output end of the delivery waveguide, transforming laser beam divergence inside the waveguide into a spot size after the lens. By varying the input convergence angle and/or launch angle of the laser beam launched into the waveguide, the output spot size can be continuously varied, thus enabling a continuous and real-time laser spot size adjustment on the workpiece, without having to replace the delivery waveguide or a process head. A divergence of the laser beam can also be adjusted dynamically and in concert with the spot size.
