Experimental evaluation of the cylindrical grinding of al sic metal matrix composites

Abstract

Metal Matrix Composites MMCs are advanced materials newlinepossessing several characteristics that make them useful in situations where newlinelow weight high strength high stiffness and an ability to operate at elevated newlinetemperatures are required Among modern composite materials particularly newlinediscontinuous reinforced materials such as aluminium matrix composites newlinereinforced by SiC particles have become practical engineering materials due newlineto their superior performance viz high mechanical properties wear newlineresistance low coefficient of thermal expansion excellent thermal newlineconductivity and nonflammability However because of the existence of newlinehard SiC reinforcements in their structure they are difficult to machine newlineWhile machining AlSiC composites using conventional methods the newlinepresence of hard SiC particles causes problems like cracking and splintering newlinemaking it necessary for finishing processes such as grinding newline newline
