Experimental study for optimal setting of machining parameters for drilling alsic metal matrix composite

Abstract

Metal matrix composites MMCs are materials which combine newlinetough metallic matrix with a hard ceramic reinforcement to produce newlinecomposite materials Aluminummatrix composites are widely used for their newlinefavorable specific strengthstiffness and corrosion resistance properties As a newlineconsequence of the widening range of applications of MMCs such as the newlineaerospace automotive electronics and metallic industries the machining of newlinethese materials has become a very important subject for the research MMCs newlineare extremely difficult to machine turning milling drilling threading due to newlinetheir extreme abrasive properties With the projected widespread application newlineof MMCs it is necessary to develop an appropriate technology for their newlineefficient and costeffective machining newline newline
