Application of Two Advanced Vision Methods Based on Structural and Surface Analyses to Detect Defects in the Erichsen Cupping Test
Due to the wide range of various sheet metal grades and the need to verify the material properties, there are numerous methods to determine the material formability.One of them, that allows quick determination of sheet metal formability, is the Erichsen cupping test described Resistance Brake in the ISO 20482: 2003 standard.In the presented work, t
