Modified Cross-Wedge Rolling for Creating Hollow Shafts

open access: yesProcedia 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
