Guo et al. analytically correlated the grinding wheel wear with the grinding power consumption during the grinding of nickel alloy with electroplated CBN wheel. Recently, Shi et al. [17] improved such model by eliminating the requirement of a prior knowledge of the grit wear flat area and the regime of the average contact pressure.
