By the 1600s, rolling machines, rather than small, handdriven rolls, were known to have been in operation and iron was just being introduced as a metal capable of rolling. By the late 1700s, the first hot rolling mills appeared ...

Results of a study investigating a skew rolling process for elongated axisymmetric parts are presented. Despite the fact that the skew rolling technique for producing such parts was developed and implemented in the midtwentieth century, there are no studies on this problem. The first part of this paper presents the results of FEM modelling of skew rolling stepped axles and shafts (solid and ...
