Abstract
Influence of roughness and thermal conductivity of processed steel on the choice of gas laser cutting parameters
Incoming article date: 10.02.2022The article analyzes the influence of the roughness and thermal conductivity of the processed steel on the choice of gas laser cutting parameters. The authors describe the possibilities and advantages of using gas laser cutting in production. The article presents the results of an experimental study of samples made of St3 steel of various thicknesses. An analysis of the data obtained showed that with an increase in the gas laser cutting speed, the roughness parameter increases, and the laser power has practically no effect on the roughness value. The authors also attempt to take into account the influence of the thermal conductivity of the processed material on the choice of laser cutting characteristics. It was found that in order to ensure a minimum roughness for steels with higher thermal conductivity, increased power and cutting speed should be used.
