Abstract

On the basis of the quantitative physical model of gas-assisted laser cutting of thick metal in air or oxygen the maximum cutting velocity and thickness are calculated. The effect of beam shape on cutting efficiency is considered. The theoretical results are in qualitative agreement with the experimental data at the carbon-dioxide-laser of 7...15 kW. It is shown that the cutting velocity can be increased substantially by means of beam shape and gas jet optimization.
