Abstract

A laser engraving apparatus is provided. The apparatus includes a laser device for outputting a laser beam. A workpiece to be engraved is positioned on a support member. To direct the laser beam to a predetermined position relative to the workpiece, the apparatus includes a beam delivery system. The beam delivery system includes a number of mirrors and a carriage assembly. The carriage assembly includes an X-carriage and a Y-carriage. These two carriages are moved to cause movement of two of the mirrors whereby the laser beam can be controllably and simultaneously positioned in both X and Y directions to engrave the workpiece. The components and location of the X and Y carriages relative to the workpiece and laser device, as well as to each other, result in a portable unit. The laser engraving apparatus is also modular in that it is able to communicate with a separate, independent controller for use in operating the apparatus to engrave any one of a number of selected, creative patterns.
