Sheet metal stretches as it is bent so it's not exactly a centerline. The second most important aspect to keep in mind is that the length of the press brake is irrelevant to our calculations, what does matter is the length of the sheet metal we intend to bend. At the bottom of the screen is a bar that lets you choose whether you want to try finding a variable for a single bend of metal, a double bend of metal or a bar of metal with a random number of bends. Through analytical method is used to find the effect on bending strength and buckling strength after changing the shape of the cross-section of the sheet due to folding at 90°.
