“…For laser cutting of stainless steel and plastics there are similar influences of laser cutting speed, power of laser beam as well as purity or pressure of assist gas like for the cutting sheets made of the carbon steel. The better surface roughness is for a quantum laser than for a CO2 gas laser cutter at the same cutting parameters [13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31] .…”

The results of laser cutting speed influence on the quality of machined surface, defined by the Ra roughness parameter and the shape errors, in case of machining two types of steel: i) P265GH, ii) 1.4307 are presented in the paper. Two CO2 laser cutters with maximum power of the laser beam 4000W and 3200W were used for the investigation. The characteristics of the roughness parameter Ra depending on the laser cutting speed v c are presented. The diagrams of shape deviation of the machined specimens for the greatest and lowest values of the Ra for the both laser cutters are also presented. The deviation values from the theoretical profile of the particular samples, taking into account the type of the cut-out shape profiles (circular, linear) are calculated.
