FEM Simulation Analysis of Cross Wedge Rolling Process

Advanced Materials Research, 2011
This paper investigates the interfacial slip between the forming tool and workpiece in a relatively new metal forming process, cross-wedge rolling. Based on the finite elements method, three-dimensional mechanical model of cross wedge rolling process has been developed.

Theoretical and experimental analysis of cross wedge rolling process

International Journal of Machine Tools and Manufacture, 2000
A summary of the cross wedge rolling process (CWR) modelling method being developed by the author is presented in the present study. The forming zone has been divided into several layers to calculate their contact pressure as in the case of the rotational compression process.

Evaluation of Critical Interfacial Friction in Cross Wedge Rolling

Journal of Tribology, 2000
For the purpose of characterizing excess initial slip, the critical value of interfacial friction in the cross wedge rolling (CWR) process is investigated. After describing CWR and its failure mechanisms, an analytical method is presented for determining the critical friction condition in a cross wedge rolling process.

Numerical Modeling of Cross — Wedge Rolling of Hollowed Shafts

AIP Conference Proceedings, 2004
In this article, the results of numerical calculations and experimental work of the cross‐wedge rolling (CWR) processes of hollowed shafts, realized with mandrels and without them, are presented. The results of numerical calculations for the CWR process of three rolls were also provided. On the basis of the calculations it was stated that the method of

Cross-Wedge Rolling of Shafts With an Eccentric Step

Journal of Iron and Steel Research International, 2011
A new concept for forming eccentric shafts on the basis of the cross-wedge rolling (CWR) process was presented. This concept was based on the application of special guides, which, by acting on a billet, lead to its controlled movement in the vertical direction. This movement made possible eccentric cutting of tools into the billet. FEM calculations and
