Assessment of Erichsen Cupping Test Results by Means of Laser Speckles
Abstract
The paper presents a proposal of using the Erichsen cupping test to specify additional parameters of the tested sheet metal aside from the commonly determined depth of the cup when cracking appears. For this purpose the vision system was used to enable the detection of the localized necking and cracking of sheet metal during Erichsen cupping test by using the speckles effect. The differences in the depth of cup between the start of the localized necking and the cracking were presented for sheets made of aluminum, deep drawing steel and high strength steel. This information can be used to compare the characteristics of different grades of sheet metal and it can be taken into account in designing of the stamping process.
