Method & Evidence

AimTo develop and describe a modified cross-wedge rolling process capable of producing hollow shafts and assess its potential for resource efficiency.

MethodProcess development and description

ProcedureThe research details a modified cross-wedge rolling (CWR) process that incorporates two mandrels acting in conjunction with tooling wedges. This system induces axial fracturing within the billet, which the mandrels then exploit to penetrate and form a hollow core. The paper analyzes the interplay of tool geometry, kinematic system, and processing parameters.

ContextManufacturing of rotationally symmetric components, particularly shafts.
