The grinding wheel wear reduces the machining accuracy and causes the residual stock removal of workpiece after the grinding process. One of the causes of the grinding wheel wear can be mentioned the grinding resistance. On the other hand, it is known that the grinding resistance depends on the stiffness of the grinder. The grinding wheel wear may be depended on the stiffness of the grinder if the grinding resistance by the stiffness of the grinder changes. Therefore, machining accuracy will be improved if the workpiece support stiffness can be properly controlled. This study aims to investigate the effect of the difference in the workpiece support stiffness in cylindrical grinding on grinding wheel wear. As a result, it was clarified that the difference in the workpiece support stiffness affects the normal resistance, grinding wheel wear and decreased amount of depth of cut in plunge grinding. Moreover, difference in the normal resistance affects the grinding wheel wear.
