Laser marking machine operators set up and tend laser marking or engraving machines designed to precisely carve a design in the surface of a metal workpiece by use of a moving controller and an engraving laser beam point attached to it that traces patterns on the metal workpiece's surface. They make adjustments to the machine in terms of laser beam intensity, direction and speed of movement. They also ensure the laser table, used to perform laser machine engravings on and guides the laser beam, is properly set up.
