Physical Modelling of Cross-Wedge Rolling of Ball Studs [PDF]
Archives of Metallurgy and MaterialsThe publication presents and reviews the results of a physical modelling study of the Cross Wedge Rolling process of ball-studs. The ball-studs was formed in a double system from C45 steel at 1050°C, while the physical modelling process was performed on ...

Novel damage calibration test based on cross-wedge rolling
Journal of Materials Research and Technology, 2021 This article presents a new calibration test for damage functions that uses the cross-wedge rolling method (CWR). In this test, the forming conditions were altered by applying wedges with decreasing forming angle on conical-cylindrical samples.

Numerical simulations of screw spike, worm and gear rolling [PDF]
, 2010 Cross wedge rolling (CWR) is a very efficient technological process which has a favourable effect on properties of rolled products. At the same time, however, this forming technique causes complex non-linear problems resulting from variable contact ...
