There are three major varieties of laser cutting: fusion cutting, flame cutting and remote cutting. A continuous cut is produced by moving the laser beam or workpiece under CNC control. A co-axial gas jet is used to eject the molten material and create a kerf. Laser cutting is mainly a thermal process in which a focused laser beam is used to melt material in a localised area.

Able to heat, melt and even vaporise material, lasers are seen as the ideal medium for channelling intense but controllable energy. They offered an entirely new form of energy which in turn lent itself to uses in manufacturing, medicine and communications.
