Physical and numerical modelling of the forging process of a complex shape axisymmetrical part has been presented. Three different solutions of forging technology have been analysed in order to obtain improvement in the metal flow kinematics in the last stage of forging in finisher die, as well as, favourable distribution of mechanical parameters in workpiece and tools. Improved design of preform produced divided flow pattern in the finisher die, resulting in reduction of loading and stresses in tools.
