Tool Dynamics During Single Point Incremental Forming Process


AbstractThe single point incremental forming manufacturing process has become increasingly used because of its flexibility in manufacturing single pieces. There exist in the literature many research works that focus on studying the different phenomena observed during the single point incremental forming process of sheet metal blanks such as material fracture criterion, forming limit diagram, friction and force effects, mechanics of deformation, material spring-back, optimization processes, among others. However, the tool and the experimental set up dynamic effects that could influence the single point incremental forming process have not been addressed. Therefore, the aim of this research focuses on studying the dynamics interaction among the tool, the experimental set up and the sheet blank during the forming process. To quantify these effects, we have dynamically characterized the process response behavior and used finite element simulations to identify the resonance vibrational frequencies as well as the magnitude of the maximum von Mises stresses and found that if we want to avoid undesirable vibrational effects that could affect the final formed part, we need to have a robust experimental set up
