Abstract
Counter-roller spinning is an effective method for forming large metal cylindrical parts. In this paper, the radial, axial and tangential counter-roller spinning forces were analyzed. The simulation analysis model was established and the counter-roller spinning was simulated based on the commercial FEA software, SIMUFACT-FORMING. The influence of different thinning ratio, feed rate and forming angle of roller on spinning force was analyzed. It can be seen that the deviation between the simulation average radial spinning force and the experiment average radial spinning force was less than 12%, and that of the axial spinning force is less than 10.5%, which can effectively guide the spinning process test.
