Abstract: Basing on the analysis of the traits of the roll forging process, a system-model of computer simulation has been established. Three-dimensional rigid-plastic FEM has been used for the simulation of the deformation process in the oval and round pass rolling, including the entering, rolling, and separating stages. The analysis was conducted using the Deform-3D ver. 5.0 code.The important information concerned with the deformation area characteristic, material fiow, and velocity field has been presented. Otherwise, the location of the neutral plane in the deformation area was shown clearly.
