Kinematics analysis in radial/axial ring rolling

The relationship of radial and axial feed distribution for the radial/axial rolling process of ring with rectangle cross-section was established according to the rolling curve. By employing the principle of volume incompressible, the kinematics equations for the radial/axial ring rolling process were developed to improve the precision and efficiency of the existing formula. To verify the proposed kinematics equations, the ring rolling experiments were carried outcorrespondingly. The calculation results agreed very well with the experimental data, which indicates that the developed equations can accurately describe the kinematics of radial-axial ring rolling.
