The most important phenomena contributing to laser cutting are heatiu of the workpiece by absorbed laser radiation and exothermic reaction, heat loss due to t rmal conduction and evaporation and melting of the workpiece in the vicinity of the focus of the laser beam. Material removal takes place since liquid material is blown away by the oxygen flow and due to evaporation. To obtain a deeper insight into these main phenomena of laser cutting and to understand their relative importance, heating of the workpiece and material removal will ne closely regarded and analyzed.
