Abstract

In the paper is presented a numerical method for determining the thermal field in the material as well as the parameters characterizing the course of machining in conditions of surface vaporization under the impact of single pulses of laser radiation. There has been design. ed a computer program as well as computations were carried out for tungsten copper and titanium submitted to the impact of rectangular and Gaussian pulses. The following parameters have been determined as time functions: temperature distribution in the material shape and depth of the cra ter in formation rate of machining process efficiency energy enclosed in the material amount of energy required for removed material evaporation.
