| Abstract: | The basic principle of digital single point incremental forming of sheet metal was described. Finite element software LS-DYNA was used to analyze the stress distribution in the contact zone of implement head and sheet metal under the condition of different forming angles and with implement head forcing down. The effects of different forming angles on the forming of sheet metal were studied by analyzing and comparing the simulated data. Then an idea was proposed for the raise of the forming height of straight wall components and the effect was proved in the experiment. |
