Abstract

A lumped parameter mathematical model is developed to relate the cut depth to the laser cutting parameters and material properties. The model takes into account the threshold power of the incident laser beam for the initiation of cutting and modifies an earlier cutting model so that it applies to a wide set of process parameters ranging from low to high laser powers and slow to Fast cutting speeds, Plain steel is taken as an example to show the effects of various process parameters such as the laser power, spot size and cutting speed on the cut depth, Special emphasis is given to the effect of laser mode structure on its cutting capability.
