Abstract
A method for manufacturing a vehicle wheel includes: a casting process of manufacturing the wheel in a one-piece body having a forming end and a temporary flange protruding at inner and outer sides of the wheel, respectively, wherein the one-piece body further includes a resonance chamber forming groove; a primary shape machining process of forming a stepped part at an outer circumferential side of the resonance chamber forming groove; a flow forming process of bending the forming end to be seated on the stepped part; a friction stir welding process of integrally bonding a portion where the forming end and the stepped part are in close contact with each other; a fine machining process of removing the temporary flange; and a sound-absorbing hole machining process of forming a sound-absorbing hole for communicating between the resonance chamber and an interior space of a tire in the forming end.
