The deformed geometric zones during radial axial ring rolling are analyzed qualitatively and quantitatively. The kinematics and geometry relationships between the radial roll gap and axial roll gap are derived and it is shown that the rate of increase of the ring diameter is mainly affected by the radial and axial feed rates, the rotating velocity of the main roll and the geometric dimensions of the ring. In addition, the kinetic equations of the driving units, the hydraulic servo system and DC motor speed regulating system are also derived. Based on the kinetic equations, it is proposed that the same fuzzy control strategy can be used for the driving units and driving control can be realized by the intelligent template with a single chip computer.
