Patent ID: 8253065

Claim:
A laser engraving system for engraving an unengraved workpiece, comprising: an image processor configured for building a workpiece model corresponding to an unengraved workpiece, partitioning the workpiece model into at least one section, generating at least one two-dimensional pattern, determining relative position values of the at least one section, and outputting signals of the relative position values and the at least one two-dimensional pattern, the image processor defining respective reference plane in respective section, and the two-dimensional pattern generated by reflecting a three-dimensional pattern onto the reference plane, the reference plane selected from a variety of planes of each section according to a rule that distance of each point of the section from the reference plane are minimized and not exceed 1 millimeter; an engraving controller electronically coupled to the image processor, receiving the signals of the relative position values and the at least one two-dimensional pattern from the image processor; a mechanical arm electronically coupled to the engraving controller and controlled by the engraving controller in such a manner that the mechanical arm positions an unengraved workpiece according to the signals of the relative position values; a laser electronically coupled to the engraving controller and controlled by the engraving controller in such a manner that the laser engraves an unengraved workpiece according to the at least one two-dimensional pattern; wherein the engraving controller comprise a laser controller module and a mechanical controller module, the laser controller module and the mechanical arm controller module are electronically coupled to the image processor, the laser controller module receives the signals of the two-dimensional pattern, and the mechanical arm controller module receives the signals of the position values.
