Silvia FERENŢ-PIPAŞ (PĂDUREAN), Ovidiu CHIRIBĂU, Ambrozie PURA, Cornel CIUPAN

Abstract


This article presents a comparative analysis of the main processes of modern cutting: water jet, plasma and laser cutting. Technical characteristics and the profitability of these cutting machines will be reported. This article also presents the evolution of cutting speed for carbon steel, a stainless steel and aluminum, processed with a laser power of 4000 W, a plasma jet, current intensity 200 A, respectively with a jet of water with the power of 50 hp. Next, it is presented a comparative set regarding the costs of the modern cutting machines. It is presented the typical criteria used for most process evaluations.

 Key words:  laser, plasma, water jet, cut, cutting speed, costs, material
