Abstract
The paper presents the results of experimental and theoretical studies of the patterns of influence of the pressure of the
assist gas (nitrogen), the focus position relative to the surface of the part, and the cutting speed on the roughness parameters of
the obtained surfaces when cutting 12 mm stainless steel AISI 304 using a 12 kW fiber laser. Based on the results of a systematic
complex of experimental studies using the Statistica package, regression models of the process were obtained, their accuracy
and adequacy were substantiated. Experimental verification confirmed the effectiveness of using the most accurate regression
model to determine the parameters of the modes that ensure high quality and productivity of cutting.
