Abstract: A method for creating a three-dimensional engraving within a solid. A three-dimensional illustration of the solid is scanned into a numerical controller associated with a machining center. The 3D illustration is projected in the solid according to individual depths of cut. The solid is machined according to its project depths. Shading is accomplished according to depth of cut and by immersing the solid into oxide bath and successively abrasively removing a darkened coating according to depth of cut. Powder coating with a thermoset plastic, baking and curing steps provide a transparent coating to the solid.
