Paper Abstract

Using various methods of investigation (mathematical modeling, modeling of processes of auxiliary gas outflow using physical models simulating the real ones, visualization of real processes of laser cutting), the influence of the geometry of the system the nozzle - the obstacle and of the nozzle on the power and hydrodynamic parameters of the auxiliary gas jet is shown. The role of gas on the precision and the surface finish of precise contour workpieces of sheet metal is revealed. Using models geometrically simulating the real ones, the structure and the form of the gas jet at the same time of its outflow from the nozzle and the slot are shown. The dimensions of the inlet of the nozzle (d0) and the distance to the obstacle ((Delta) h), at which the gas jet shows the maximum effect of penetration into the slot, are determined.
