INVESTIGATE THE BULGING EFFECT OF METALLIC SOLID CYLINDER UNDER COLD UPSETTING USING FINITE ELEMENT ANALYSIS

Amit Bhumarker, Abhishek Singh

Abstract


Friction is an integral part of metalworking and manufacturing processes due to the relative motion and forces continually acting on tools, dies, and workpieces. Friction both raises the effort and consumes energy. However, measuring friction is not straightforward and cannot be considered an independent parameter. In many metal-forming procedures, the impact of friction is just as crucial as other quantifiable factors. Various methods have been used to estimate friction, assuming that no barreling or bulging takes place during forging, and calibration curves are created based on this assumption. However, barreling can notably influence the friction factor developed during deformation. This study compares experimental data on the deformation of commercial aluminium with that obtained through FEM modeling.
