We have subsequently considered after-effect of initial roughness on the finished surface. Primarily the projections of the small screws of the five sorts of material as a model of roughness are cut by a straight lapped edge and then the forms at the cut points are observed. Secondarily the rough eurface of the same material is cut in the same way and the profiles after finishing are compared with those before finishing with singular correlation coefficient, γ. All these coefficients are lower than the coefficient, ρ in the case of geometrical cutting and this is concerned with result in model experiment. It is caused by pressing effect in shallow range and by built up edse in deep range, So a coefficient |ρ-γ|/(1-ρ) is convenient to estimate the after-effect. It varies accordins to material, cutting condition and gradually begins to vanish with the depth oner height of roughness.
