if n is the rpm of grinding wheel, ρ = surface density in grains/mm 2, then number of active grains on boundary of wheel and thus number of chips produced per unit time = πndw ρ. it will be seen from here that wheel will appear to be softer, if n, d, or ρ decrease, or f or d increase, because the value of f av will increase and cause a more frequent dislodging of the abrasive grains.
