Jan 01, 2011 Equivalent to the grinding ratio G according to the dressing ratio G d is the ratio between dressed grinding wheel volume V sd and dresser wear volume V d: (2.6) G d = V sd V d. The most important parameter in sharpening is the material removal rate. The amount of required abrasive in sharpening determines the effectiveness of the process
