Summary:

Cross wedge rolling (CWR) is an efficient means of distributing volume along a cylindrical preform. The process control is far superior to traditional manual drawing operations used to produce hand-rolled preforms. Wedge rolled preforms are thus popular for high-volume forged components. The process typically results in a much higher material yield than traditional preforms.

Flat, two-die cylindrical and three-die cylindrical cross wedge rolling operations are regularly modeled using DEFORM-3D. Its FEM engine includes special modeling techniques to enhance speed, accuracy and robustness of complex rolling process.

The first half of this video displays die contact during the rolling process. It is followed by a prediction of the plastic strain accumulation throughout the operation.
