COMPARISON OF DIFFERENT UNCONVENTIONAL THERMAL ENERGIES FOR STEEL CUTTING PROCESS

Abstract

ABSTRACT:- different unconventional heat sources for material processing werediscussed . The heat sources such as plasma arc, electron beam and Co2 laser were employedpreviously by other researchers, while " Co2laser– gas mixture" system was studied duringthe present research .Comparison between the results of present work with the others mentioned above wasmade . The parameter which was adopted for comparison is the "energy consumed per unitlength" for particular thickness .The parameter is based on the equation which was suggestedby the author of this research .Linear relationship between energy per unit length with thickness forCo2 laser aloneand "Co2laser – gasmixture " was found, while for other heat sources it was found out of theproportionality. This comparison showed the superiority of the "Co2laser –gas mixture"system over the other heat sources during cutting mild steel.
