Parameter LN-IE can be helpful in formability comparison of different grades of sheet metals.

Extended evaluation of Erichsen cupping test results by means of laser speckle – ScienceDirect

The paper presents a proposal of using Erichsen cupping test to determine the additional parameter — the height of the cup LN-IE at the moment of localized cuppinv in sheet metal, which usually precedes fracture of sheet metal.

The test cylinder is installed at erichsen cupping test angle, so that the test procedure can be carried out comfortably when seated. Erichsen cupping test of manufacturing costs by making spot checks on the drawing quality of cold rolled sheet during production or in the process department.

Determining the most appropriate sheet thickness for a particular drawn workpiece to optimise the ratio of price to suitability for the manufacturing process.

Author links open overlay panel A. Without special test preparation it is immediately possible to establish if the material supplied has the prescribed drawing quality. Sheet Metal Formability – Ductility Testers.

Test Tools for ERICHSEN Cupping Test on Strip and Sheet Metal

When carrying cjpping the Cupping Test the sheet metal specimen in the form of a strip is inserted in the test cylinder and centralised by locating diagonally.
