A model of the cutting mechanism in grinding -

1979-3-1 · This paper presents a contribution to the understanding of the cutting mechanisms in grinding. An analysis of the grinding mechanism is made on the basis of the cutting-edge geometry and the kinetics involved. One physi- cal model has been developed to explain all the phenomena from friction to ploughing and cutting under plane strain conditions.
