Abstract: The work is devoted to a quantitative assessment of friction wear. For this purpose, a geometric model of the surface roughness of the wear material has been constructed. Is accepted the hypothesis that the edges of the protrusions are the lines where the maximum shear stresses occur. The position of these lines has been determined. An area of variation of the angle, which determines the position of the protrusions on the border, is found. The maximum value of compression pressure, at which friction wear begins, is determined, a formula is found for the mass of the body part being worn.
