Materials for, and methods of, colorizing a metallic surface with micro-gratings using vibration cutting technologies are provided. Micro-gratings on aluminum, brass, and stainless steel surfaces can be rapidly created to effect, under illumination, at least one color observable in the visible spectrum using elliptical vibration texturing, a vibration-assisted mechanical cutting process. The modified metallic surface can display multiple visible colors, an iridescent effect caused by changes in one or more cutting parameters employed to produce the micro-gratings, the angle of illumination by an incident light, and/or the viewing angle of the surface under illumination.

The present invention relates to apparatuses, systems, and methods for defining positions where characters such as text, numbers, symbols, or the like are to be inscribed. Specifically, the positions may correspond with geometric shapes including, without limitation, arcs, circles, angles, lines, rectangles, or the like. Even more specifically, the apparatuses, systems, and methods define the positions using a plurality of points, such that information such as coordinates, angles, radiuses, perimeters, centers, heights, lengths, circumferences, or the like are not required. Further, measuring tools, prints, or operator skill/knowledge is not required.
