The Equation of Instantaneous Speed Ratio between Roller and Workpiece
The instantaneous speed ratio between roller and workpiece is not only the basis of the relative movement relationship but also the key to deriving the curve of non-rotating shafts with cross wedge rolling. In the paper, the instantaneous speed ratio was analyzed by using FEM. Then, the equation of instantaneous speed ratio equation was regressed by using the statistical analysis software. In the meantime, the experimental rolling equipment was designed to verify the accuracy of the regression equation. Satisfactory consistency was demonstrated by comparison of the theoretical values and results obtained from experiments.
