FIELD: plastic working of metals, possibly rolling on shafts toothed and splined profiles.
SUBSTANCE: method comprises steps of drilling in blank (before deforming it) cylindrical opening whose axis coincides with geometry axis of blank. Diameter and length of said opening depend upon value of total volume of deformed material, its physical and mechanical properties, working profile of roller and deformation rate.
EFFECT: lowered deforming efforts, improved fatigue strength of part, enhanced accuracy of profile along its length, increased useful life period of rollers.
