Formation of grinding streaks by a single diamond abrasive grain in ultra high speed grinding

Abstract

To enlarge the basic knowledge concerning the ultra-high speed grinding process, the groove formation generated by a single abrasive diamond grain was investigated in a peripheral grinding wheel speed between 30 and 230m/s. The single grain cutting ability was studied depending on the wheel speed, workpiece speed, workpiece material and grain size. The result of grinding force measurement and SEM observations of grooves and grains tips show specially that by increasingthe wheel peripheral speed the cutting ability of the diamond grain expressed in terms of grinding forces, grinding energy and area ratio between the bottom and the sides of the grinding streaks increases and its wear decreases.
