Paper Abstract

The results of experimental investigation of distributions of melt material remaining under workpieces depending on the nozzle pressure pn are presented. It is demonstrated that there exist two critical pressures pn,1 and pn2 that separate the regions of full confinement, partial removal and full removal of melt. The estimations of pn,1 and pn,2 based on the relations between the time of melt gathering through the cutting front and the Rayleigh instability development are fulfilled. The obtained experimental results are in a satisfactory agreement with the performed estimations.
