FIELD: process engineering.
SUBSTANCE: invention relates to metal forming, particularly, to producing rings by means of elastic male die and rigid female die. Proposed method comprises locking workpiece between rigid female die with shaping working surface and elastic male die. Rigid male die is fitted inside elastic male die. Working surface shape is produced by deforming the workpiece on pushing rigid male die through elastic die. Surface relief is shape starting from its center. Pushing rigid male die through elastic male die is accompanied by redistribution of elastic male die volume and workpiece strain wave motion along its generatrix from center to edges.
EFFECT: smooth surface with no flutes.
