May 09, 2018· ψ is the semi-angle of the sharp cone of an abrasive grain; P is the force acting on the grain. (alpha_{text{K}}) and m are numerical factors in ranges of 0.03–0.04 and 0.33–0.50, respectively. Force P determines the ratio, yet in practical machining, it varies with process parameters, which renders the model inconvenient to use.
