Operators without previous knowledge or experience can be quickly trained to operate the machine continuously.

It is based on the phenomenon of laser speckle. Determining the most appropriate sheet thickness for a particular drawn workpiece to optimise the ratio of price to suitability for the manufacturing process.

The testing machine, Modelis suitable: Erichsen cupping test links open overlay panel A.

Test Tools for ERICHSEN Cupping Test on Strip and Sheet Metal

It is possible to delay the crack detection using a potentiometer. Lowering erichswn manufacturing costs by making spot checks on the drawing quality of cold rolled sheet during production or in the process department.

As the testing machine is equipped with the function “automatic stop at specimen failure” the cupping procedure is automatically interrupted erichsen cupping test a crack appears so that an objective test result will always be achieved. Check if you have erichsen cupping test through your login credentials or your institution. For more information, visit the cookies page. Keywords Erichsen cupping test. Description This testing machine is available as a work-top model with compact dimensions which requires only a minimum of space.

The necessary control erichsen cupping test are clearly laid out srichsen the front panel. Erichsen cupping test has usually been used to determine the height of the cup at the moment of sheet metal fracture, defined as the Erichsen Number IE.

The entire erichsen cupping test procedure runs automatically, including crack detection. The paper presents a proposal of using Erichsen cupping test to determine the additional parameter — the height of the cup LN-IE at the erichsen cupping test of localized necking in sheet metal, which usually precedes fracture of sheet metal.

The good functional layout of Model makes this machine particularly user friendly. For this purpose, a method of localized necking detection was developed.

Abstract Erichsen cupping test has usually been used to determine the height of the cup cypping the moment of sheet cuppkng fracture, defined as the Erichsen Number IE. Parameter LN-IE can be helpful in erichsen cupping test comparison erichsen cupping test different grades of sheet metals.

The sturdy design and the hydraulic oil system employed ensure that minimum wear is experienced so that a good repeatability of the test results is assured over a long period of time. This Cupping Test Machine is especially designed for an easy and quick quality conformance inspection and quality control on sheet and strip metal, but also particularly suitable for production monitoring because of its sturdy construction. The results of height measurements were presented for three different grades of sheet metals used in the automotive industry: This testing machine is available as a work-top model with compact dimensions vupping requires only a minimum of space.
