One of the modest methods in producing seamless rings is the radial-axial rolling process. Modeling the guide and conical rolls and calculating their respective forces are essential in the simulation of the radial-axial rolling process. The main objective of the present study is to propose a novel approach in the modeling of guide and conical rolls used in the radial-axial ring rolling process. The parts dedicated to the simulation of the process are two complicate formed rings made of Ti-6Al-4 V alloy. To validate the results obtained via the simulation, practical experiments were carried out in which a simple ring made of aluminum alloy was rolled, and practical results were compared with simulation results. Comparing the results shows a proper agreement between simulation and practical results. Consequently, the obtained radial and axial forces and moments from the simulated process can be used to select proper machine tools for the purpose of mainly producing two complicate formed rings.
