Purpose: This article presents the quality aspects of both laser and water-jet cutting methods. Design/methodology/approach: Laser cutting was made with Laser C02 TruFlow 6000 machine. Cutting abrasive jet was held on the water-jet. Cases on cutting stainless steel EN 1.4016/AISI 430 of different thicknesses are discussed in a comparison study. Following the tests, the surface roughness of the machined surface was measured by using optical profilometer. Using high-resolution optical microscope the kerf taper ratio and kerf wideness were measured. Findings: The study included examination of thermal deformation and burr formation. Water-jet technique is devoid of thermal effects and burr formation are very small, since a little heat generated by the water-jet is absorbed by the water. Laser technology thermally deformed material, which is growing with the increase in thickness of the material. Research limitations/implications: The cut surface roughness, waviness and taper cutting surface are higher in the hydro-abrasive technology than the laser cutting. Cutting speed for laser and water-jet were compared. Laser cutting technology has proved to be faster than water-jet cutting. Finally, was carried out the analysis 3D surface topography. New generation of instruments enabling a non-contact 3D assessment of a surface quality profilometer. Originality/value: The selection of the appropriate cutting technique is important, therefore, a thorough examination of kerf allows to select the correct cutting technique.
