FE Simulation of Hot Single Point Incremental Forming Assisted by Induction Heating

Single Point Incremental Forming (SPIF) of high-strength is challenging. It requires high forming-forces, also the materials exhibit relatively low formability and distinctive springback behavior. Consequently the forming process is limited and the geometrical accuracy is decreased. Therefore hot SPIF was introduced. In the present study, with induction assisted locally heated single point incremental forming (IASPIF) a variant of this approach is investigated. This process was accomplished by forming on the upper side of the sheet using the forming tool while the heat was generated by a circular heating disc moving on the lower side of the sheet. The heat was transferred from the heating disc to the sheet during forming. The sheet was heated locally by this method, in which the heating disc was following the forming tool, by applying the same path for both of them.
