Geometry of tooling imposes a minimum bend dimension. Also known as press braking flanging die bending folding and edging this method is used to deform a material to an angular shape. V die width is 6 8 times the plate thickness. Bending is one of the most common sheet metal fabrication operations.

Calculate unfold size with bend allowance chart. When the sheet metal is put through the process of bending the metal around the bend is deformed and stretched. Understanding the bend allowance and consequently the bend deduction of a part is a crucial first step to understanding how sheet metal parts are fabricated. 3d cad files are converted into machine code which controls a machine to precisely cut and form the sheets into the final part.

Sheet metal fabrication is the process of forming parts from a metal sheet by punching cutting stamping and bending. Use the minimum bend dimension values in the charts below for your minimum closeness of cutout to a bend. An air bend force chart or force chart breaks down a number of key components of sheet metal bending in an easy to reference format. As this happens you gain a small amount of total length in your part.

Being able to read a bend force chart is crucial for any brake press operator and sheet metal engineer. This is done through the application of force on a workpiece. Refer to the chart for values for folder as well as various press brake tooling combinations. The diagram shows one such mechanism.
