FIELD: metallurgy.
SUBSTANCE: method is in that treatment is implemented with usage of its end cylindrical or coned cutters with working section, at least, past of which surface is implemented curvilinear, with treatment implementing by means of milling by section of curved surface, fulfilling conditions current deviation angle between cutter axis and tangent plane to work piece surface in contact point of cutter and treated surface of detail is less or equal to maximal deviation angle between cutter axis and tangent plane to curvilinear cutter surface. Additionally curved surface radius of cutter is defined from of introduced ratio depending on radius of curvature of normal section of workpiece surface, passing through the cutter axis, tolerance for ribbing and feed to line.
EFFECT: productivity improvement of treatment and improvement of treated surface.
