Springback happens in all sheetmetal applications to various degrees. Determining the amount and location of this springback is the subject of die simulation and other forming analysis softwares such as Dynaform, FastForm, Autoform, and PAM-Stamp Specifically what these systems do is calculate a thing called a compensation model that, once deployed within the forming statons of a die, yields a "sprung-back" part that hopefully will springback to the part's nominal geometry. Up to now, there … [Read more...]
