Abstract
A method for laser engraving a three-dimensional image into a workpiece according to color shades found in an original piece of artwork. The original piece of artwork is separated into a plurality of illustrations with each illustration corresponding to a particular layer of material to be removed from the workpiece in accordance with a selected color shade found in the original artwork. The illustrations are sequentially read by laser system program software which translates the lines on each illustration into signals corresponding to laser paths. The signals are received by the laser system control assembly for directing the laser beam along the workpiece in a layer-by-layer relationship corresponding to the sequentially read illustrations. The use of the plurality of illustrations allows for a layer-by-layer removal of material in the workpiece in correspondence with the various color shades on the original piece of artwork. As such the power of the laser need not be continuously adjusted according to the desired depth of penetration into the workpiece. The method allows for various images to be engraved into the workpiece in accordance with the original artwork.
