Abstract

The numerical investigations on experimentally determined cut front geometries presented in this paper show that the absorbed intensity reacts more sensitively to small local changes of the angle of the cut front than the gas velocity and the pressure. It is also found that the absorbed intensities near the top and the bottom of the cut front increase significantly when the initially regular process at high cutting speeds turns into the regime with interrupted striation patterns on the surface of the cutting edge.
