An Experimental Investigation on the Characteristics of Cylindrical Plunge Dry Grinding with Structured cBN Wheels

This paper proposes a new innovative concept approaching the optimum cylindrical plunge dry grinding. The concept is based on the individual dressing operation in order to create designed structures on the grinding wheel surface. Cylindrical plunge dry grinding experiments have been carried out by employing both structured wheels and normal wheels. The results show that dry grinding with the structured wheel leads to lower grinding forces, area-specific grinding energy, and thermal damages to the workpiece as compared to the case of grinding with the normal wheel. The relatively higher surface roughness values, although, were resulted in the case of applying the structured wheel, they may be lowered by an additional spark-out pass to the values obtained with using the normal wheel.
