LASER MACHINING SYSTEM AND MACHINING CONTROL METHOD
A laser marker has: a controller configured to oscillate a laser beam; and a head configured to scan a machining surface of a machining target with the laser light. The controller is configured to transmit, to the image processing apparatus, a command for instructing the image processing apparatus to perform a predetermined scene, when the controller is set to cause the image processing apparatus to perform the scene. When the command is received, the image processing apparatus is configured to calculate a deviation amount of the machining target relative to a reference position using image data of an image of the machining target captured by the marker head and to notify the deviation amount to the controller. The controller is configured to correct a position to be scanned with the laser beam based on the deviation amount and then cause the marker head to perform the scanning.
LASER-ASSISTED MICROMACHINING SYSTEMS AND METHODS
Laser-assisted micromachining methods and systems capable of providing flexible beam positioning and low incident angles. Such laser-assisted micromachining systems preferably include a laser beam source, a cutting tool, means for engaging a workpiece with the cutting tool, optical elements arranged to define a path of a laser beam emitted by the laser beam source wherein the optical elements include at least a first mirror mounted in fixed relation to the laser beam source, and means for adjustably mounting a second mirror to project the laser beam onto the workpiece in proximity to the cutting tool and at an incidence angle relative to a surface of the workpiece.
Garments with finishing patterns created by laser and neural network
Software and lasers are used in finishing apparel to produce a desired wear pattern or other design. A technique includes using machine learning to create or extract a laser input file for wear pattern from an existing garment. Machine learning can be by a generative adversarial network, having generative and discriminative neural nets. The generative adversarial network is trained and then used to create a model. This model is used generate the laser input file from an image of the existing garment with the finishing pattern. With this laser input file, a laser can re-create the wear pattern from the existing garment onto a new garment.

METHOD FOR THE MATERIAL-REMOVING LASER MACHINING OF A WORKPIECE
A method for the material-removing machining of a workpiece by laser beam pulses. The laser beam pulses are directed to impact points on the surface of a volume to be removed of the workpiece in order to cut away material from the volume to be removed. Cutting away the volume to be removed results in a new contour surface to be produced on the workpiece. An impact angle of the laser beam pulses relative to the contour surface to be produced is set in accordance with a predefined condition during the removal of at least part of the volume to be removed that directly adjoins the contour surface to be produced. According to this condition, the impact angle is the same as a threshold angle (as), or somewhat smaller. The threshold angle corresponds to the impact angle at which an effective laser energy density at the impact point of the laser beam pulses on the contour surface to be produced is equal to a threshold fluence. Material is only removed at an impact point if the effective laser energy density is greater than the threshold fluence. As a result, only those volume elements of the volume to be removed that are adjacent to the desired contour surface to be produced are cut away. By controlling, in an open- or closed-loop manner, the impact angle it is therefore possible to generate with very high precision the desired contour surface on the workpiece.

SYSTEMS AND METHODS FOR REFURBISHING FUEL CELL STACK COMPONENTS
A method of refurbishing a singulated fuel cell stack interconnect includes scanning a first pulsed laser beam on an air side of the interconnect to vaporize seal and corrosion barrier layer residue without vaporizing a metal oxide layer located on the air side of the interconnect below the corrosion barrier layer residue, and scanning a second pulsed laser beam which is different from the first pulsed laser beam on the exposed metal oxide layer on the air side of the interconnect to reflow the metal oxide layer without removing the metal oxide layer.
