During forging, warping, in which the lower face of thin flange rises from the die face may occur. To better understand the effect of parameters affecting the warping in radial forging a Finite Element analysis was used to simulate the process with isotropic elastic-plastic material model. Parameters such as die corner Radius (r) or shape and ring gap Height (H), on the warping, were investigated and results were compared with experimental work. It has been shown that increasing ring gap height and die corner radius will lead to warping reduction. Also it has been shown that special profile such as chamfered die, tapered ring gap, cosine profile and polynomial function may be used to reduce the warping.
