Engraving machine operators set up, programme, and tend engraving machines designed to precisely carve a design in the surface of a metal workpiece by a diamond stylus on the mechanical cutting machine that creates small, separate printing dots existing from cut cells. They read engraving machine blueprints and tooling instructions, perform regular machine maintenance, and make adjustments to the precise engraving controls, such as the depth of the incisions and the engraving speed.
