Abstract
Analytical and numerical methods are introduced for characterizing the nature of interfacial slip in a two-roll CWR operation. The analytical method determines the critical friction coefficient in a two-roll CWR operation based on a transverse section of the tool. After being validated by comparison to experiments performed with a CWR prototype machine, a three-dimensional finite element model (FEM) was parameterized to study the influence of CWR process parameters on the global slip at more than 30 different operating conditions. Based on the analytical and numerical results, the influences of process parameters in the cross wedge rolling are ascertained and discussed.
