FIELD: mechanical engineering. ^ SUBSTANCE: method comprises rotating the blank around the axis that is in coincident with the centerline of the lathe, moving the tool longitudinally, and feeding the tool transversely. The tool is made of a cut provided with the straight main cutting edge that abuts against the straight auxiliary edge. Toe reduce roughness of the surface to be worked a cut is used whose auxiliary edge lies in the vertical plane parallel to the centerline of the machine tool and is inclined counterclockwise by an angle equal to the main angle of the plane of the standard cut stroke. The main edge of the cut abuts against the bottom end of the auxiliary edge and its extension intersects the centerline of the machine tool. ^ EFFECT: enhanced quality of turning. ^ 1 cl, 4 dwg, 1 ex |
