Set the piece of aluminum on a table or over sawhorses, and position it so the cutting area has open space underneath it. Clamp the aluminum down. Mark the start and stopping point of your cut with a grease pencil, or some similar implement that marks on sheet metal. With the aid of a ruler or yardstick, draw a straight line between the two marks. Apply a handheld rotary tool fitted with a fiberglass reinforced cut-off wheel accessory to the cutting line.
When cutting stainless steel or aluminum, the laser beam simply melts the material, and high pressure nitrogen is used to blow the molten metal out of the kerf. On a CNC laser cutter, the laser cutting head is moved over the metal plate in the shape of the desired part, thus cutting the part out of the plate. A capacitive height control system maintains a very accurate distance between the end of the nozzle and the plate that is being cut.
