Abstract

Some results on the experimental and theoretical investigation of high-pressure N₂ assisted CO₂-laser cutting of Al and stainless steel are presented. The quality of the laser cut is improved significantly at the expense of up to 50 percent decrease of the speed with respect to this for O₂ assisted cutting. The striations formed parallel to the surface of the work piece are observed. The influence of the waveguide attenuation of the focused laser beam on the quality of the kerf in depth is discussed.
