Abstract
process on sheet steel ВСт3сп of standard thicknesses, using a 2000 W fiber laser in an oxygen environment, on the cutting efficiency and quality. The study experimentally justifies the range of balanced parameters that ensure high process efficiency and quantitatively controlled cut surface quality, which complies with the requirements of ISO 9013:2017. The established cutting modes are the basis of the section of the technological instructions for serial machines of the AFX-PRO-2000-1530LD model line. The good reproducibility of the established modes was experimentally confirmed. Directions for further research using the obtained curves of the Abbott-Firestone stability coefficient are proposed
