Geometrical Analysis on Right-angle Step Forming Process in Cross Wedge Rolling

Based on geometrical models during the whole process of forming inside right-angled step in cross wedge rolling which were proposed in past years, an effective geometrical model was built through generally analyzing the geometrical influencing factors of forming inside right-angled step. Mathematic representations of the surfaces and turn radius of the part in the whole process of rolling were derived.
