You can figure out and fix springback in sheet metal bending by using an easy formula and changing your bend angle. The main formula is: Δα = σy × t / (E × R) × K σy: Material yield strength t: Sheet thickness E: Young’s modulus R: Inner bend radius K: Process coefficient Springback means the metal wants to go back to its old shape after you bend it. This can change how exact your bends are and might make parts not fit right. Springback amounts are different for each material: Material Type Estimated Springback Notes Carbon Steel 0.5° –…
