  • INVESTIGATION OF THERMAL DAMAGE DURING THE GRINDING

    During a grinding process there is possibility of both the grinder and the workpiece to be damaged. The damage can only be explained as a result of an attempt to dissociate structures by forcefully moving the atoms or molecules away from the main structure hence the release of binding energy in form of heat. If this dissociation occurs both in
