Electroplastic cutting influence on power consumption during drilling process

Abstract

The aim of this study is to report the use of non-conventional material removal process technique. It was found that electropulses (EPs) assisted drilling process improves the material machinability based on the eletroplastic influence. The influence of EPs in drilling process is studied by combining different feed rates, drills diameters, and current densities in 7075 aluminium and 1045 carbon steel. The results show that the electrically assisted drilling process improves material machinability, decreases the specific cutting energy up to 27 % in aluminium and 17 % in steel.
