  • Publication number: 20220048132
    Abstract: A computer-implemented method for generating laser engraving instructions for performing a patterning process on a workpiece surface includes receiving a first input value indicating a first laser-pulse pattern and a second input value for a laser parameter associated with a laser-engraving system; and generating a machine-command sequence for the laser-engraving system based on the first input value and the second input value.

  • Publication number: 20210379701
    Abstract: A method for laser engraving a three-dimensional pattern into a surface of a workpiece, the method comprising: positioning a laser-engraving head to engrave a first engraving region of the workpiece; and applying a first plurality of laser pulses to a set of first predetermined locations within the first engraving region, wherein the first set of predetermined locations within the first engraving region is based on a probability distribution function that corresponds to a portion of the three-dimensional pattern that is associated with the first engraving region.

  • Publication number: 20210356940
    Abstract: A computer-implemented method determining one or more parameter values for a laser-engraving process, the method comprising: executing a laser pulse model on a computer-simulated surface to generate a first surface geometry on the computer-simulated surface, wherein the laser pulse model is based on a first set of values for a set of parameters; determining a quality score for the first surface geometry; based on the quality score, performing a global optimization process to generate a second set of values for the set of parameters; and modifying the laser pulse model based on the second set of values to generate a modified laser pulse model.

  • Publication number: 20210356931
    Abstract: A computer-implemented method for generating a model of a laser-engraved surface, the method comprising: transforming a first set of values for a first set of parameters associated with a laser-engraving process to a second set of values for a second set of parameters associated with a laser pulse model; modifying the laser pulse model based on the second set of values to produce a modified laser pulse model; and executing the modified laser pulse model to direct a plurality of laser pulses towards a computer-simulated surface, wherein the plurality of laser pulses modify the computer-simulated surface.
