Method of machining parts shaped as bodies of revolution

A method of machining parts shaped as bodies of revolution by multi-cutter turning, wherein one cutter is a forming one, and the others, non-forming ones, comprising the following operations:

• arranging said cutters uniformly angularly spaced along a circumference, the axis of which coincides with that of a workpiece being machined, so that the points of said cutters are located in a single, common plane perpendicular to the axis of the workpiece being machined;
• setting said forming cutter so that the point thereof is spaced radially apart from the axis of the workpiece being machined at a distance equal to the radius of a finished part of the workpiece in a position determined by the specified shape of the finished part of the workpiece in longitudinal section thereof;
• arranging said non-forming cutters so that the points thereof are spaced radially apart from the axis of the workpiece being machined at distances within the thickness of stock to be removed, but different from the radius of the finished part to be produced, and occupy positions wherein the depth of cut by each said non-forming cutter is less than the depth of cut of said forming cutter by a magnitude equal to the height of surface micro-roughnesses produced by said forming cutter;
• imparting to all said cutters interrelated radial and longitudinal feed motions.
