Method of three dimensional laser engraving

摘要

A method for laser engraving a three-dimensional image into a workpiece includes providing a plurality of pieces of artwork which form a composite three-dimensional image. Each piece of artwork corresponds to a particular layer of material to be removed from the workpiece. The pieces of artwork are sequentially read by laser system program software which translates the lines on each piece of artwork 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 pieces of artwork. The use of the plurality of pieces of artwork allows for a layer-by-layer removal of material in the workpiece such that the power of the laser need not be continuously adjusted according to the depth of penetration into the workpiece. The method allows for various engraved images to be presented having various sloped surfaces therein.
