Thinning Process Sheet Metal

For sheet metal parts the thickness is the same everywhere.

Thinning process sheet metal.

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. Thickness of the formed sheet was measured at all the nodes along its length and the minimum was extracted for comparison. Sheet metal forming 2 810 d. Sheet metal forming process is a major point to st udy in order to ameliorate the final quality of the produced parts.

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. At this point you have two measurements. 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.

Sheet metal usually refers to a thin metal plate with a thickness of 6 mm or less. Pr 1 mm pr 3 mm. Prediction of the deformation zone thickness is an important approach to control the thinning ratio. The percent thinning is calculated as t 100 s f s.
