Thinning Process Sheet Metal

The percent thinning is calculated as t 100 s f s.

Thinning process sheet metal.

Thickness of the formed sheet was measured at all the nodes along its length and the minimum was extracted for comparison. Clinching or press joining is a bulk sheet metal forming process aimed at joining thin metal sheet without additional components using special tools to plastically form an interlock between two or more sheets. Thinning occurs at the top of the sheet metal. If you have accurate measurements you can have confidence in your results.

Sheet metal forming 2 810 d. At this point you have two measurements. Thinning is the process of reducing sheet metal to get the desired size. Sheet metal usually refers to a thin metal plate with a thickness of 6 mm or less.

When these parameters decrease the thinning moves to the bottom fig. N bh 0 2 mm. 3 g following a multivariable complex function. Pr 1 mm pr 3 mm.

Prediction of the deformation zone thickness is an important approach to control the thinning ratio. Sheet metal fabrication is a cold processing process which is commonly used for punching bending drawing and forming. 16 kalpakjian design for sheetmetal working ch. The starting thickness of your sheet metal call that s and the formed thickness of your part at the location of interest call that f.

In this fr amework several bulge tests have been developed in order to. Sheet metal is metal formed by an industrial process into thin flat pieces. An excessive thickness reducing ratio of the deformation zone in single point incremental forming of the metal sheet process has an important influence on the forming limit. Thinning helps transform sheet metal to the eventual size needed for use.

9 boothroyd dewhurst and knight. While the lower end of sheet metal thickness is 0 5 mm it can still be reduced further to form metal foil. Cooper sheet metal forming ch.
