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 ...

Modified Cross-Wedge Rolling for Creating Hollow Shafts
Procedia Manufacturing, 2018 Abstract Cross-wedge rolling (CWR) is an incremental forming method for producing rotationally symmetric components such as a basic shape of gear shaft or a preform before impression die forging. In CWR the material of a solid cylindrical billet is redistributed in axial direction while the billet diameter is reduced. Conventional CWR cannot be used

Advanced Engineering Materials, EarlyView.In this experimental study, the mechanical properties of additively manufactured Ti‐6Al‐4V lattice structures of different geometries are characterized using compression, four point bending and fatigue testing. While TPMS designs show superior fatigue resistance, SplitP and Honeycomb lattice structures combine high stiffness and strength. The resulting
