The influence of technological parameters of plasma cutting on the quality and surface roughness when cutting thick steel sheets

The purpose of this study was to analyze the effect of selected parameters on the quality of plasma cutting. The main parameter studied was the cutting speed and how it affects the roughness of the cut surface. The second parameter analyzed was the currentintensity adjusted depending on the thickness of the material being cut, which also has a significant effect on the surface quality of the metal being cut. The evaluation of the quality of the cut surface was carried out on 8, 20, 30 and 35 mm thick sheets of S235JR grade steel. Several samples were selected from each thickness for measurement and testing. The samples were cut with a MAGNUM CUT 160 plasma cutter. The results show that the current intensity and the speed of the torch pass have a significanteffect on the quality of the cut surface.
