Using buckling analysis to predict wrinkling in incremental sheet metal forming
The idea of using buckling analysis to predict wrinkling of sheet metal products manufactured by incremental forming is presented in this paper. We start from assumption that buckling analysis can be used to obtain geometry of product after first forming operation. That shape and critical buckling force are calculated using finite element method in elastic domain. The analysis was performed for various values of tool diameter. Results were tested through measurement of product geometry after first forming operation. The analysis showed that upper tool diameter can be reduced without change in product quality expressed through number of wrinkles.
