feed grinding. To understand the mechanics of grinding, let us consider a case of surface grinding, wherein the cutting by a single grain of abrasive is taking place. During surface grinding, the work-table is moving at velocity Vt (m/min) while the grinding wheel is rotating at speed N revolution per minute. AE represents the surface
