AB  - This paper presents a new concept for forming toothed shafts based on the cross-wedge rolling process (CWR). This method consists in using special inserts in the shape of flat rack bars, which, acting on a billet, extrude material from tooth spaces to tooth points. These inserts are placed at the finish end of a wedge tool. Numerical calculations (based on FEM) and experimental rolling tests unequivocally demonstrate the effectiveness of the proposed method for forming spur (straight-cut), helical, curved and herringbone gear teeth.
