ABSTRACT:
A method for engraving three-dimensional graphic intelligence upon workable stock, utilizing a three-dimensional pantograph engraving machine. A master is prepared wherein analogs of engraved graphics are defined by constant width U-cut channels. The depth of a U-channel is proportional at each point to the width of the corresponding graphic. The master is positioned at the master object receiving bed of the pantograph machine and desired analogs are traced, utilizing as the tracing element a cylindrical stylus having a diameter approximating that of the channels. A work cutting tool moves homologously with the stylus to cut the workable stock. The tool is adapted to sweep a cone during rotation, whereby a graphic is produced having a width at the surface of the work piece, and a depth at each point, which is proportional to the vertical excursion of the tracing element during its pass through the U-channel of the master, thus producing graphics having the attributes of a true hand engraving.
