How to calculate spring back when forming
Web25 feb. 2024 · Firstly, in terms of materials, it is advisable to choose materials with low yield strength or increase the material thickness while still meeting the product requirements. … WebYou can easily figure out the springback factor by performing test bends. You can see that for this particular batch of material in this centerline radius, the springback factor is 2 degrees. So whenever we want to make a bend in the future with this batch of material, we will have to “overbend” by 2 degrees.
