Hole-flanging is a crucial operation in sheet metal forming technology, where the material around a pre-fabricated hole is deformed by a spherical, conical, or cylindrical punch to create a flanged hole wall. This study aims to determine the limiting hole-flanging coefficient of AA1050-0 aluminum alloy sheet using the Cockroft-Latham ductile fracture criterion.

In this study, we propose a novel approach using the oscillation characteristics of the RMS current as the input to machine learning models, combined with the confident learning technique. Using the oscillation characteristics obtained by taking a discrete Fourier transform (DFT) of the RMS current as model input, we aim to reduce the computational requirements of the machine learning models.
