Challenges and Process Strategies Concerning Multi-Pass Double Sided Incremental Forming

Abstract:

The design domain of Double Sided Incremental Forming (DSIF) can be enhanced through the use of multipass strategies. The chosen tool gap in multipass DSIF, or multi-DSIF, is dependent on the estimated thickness of the sheet being formed, which is traditionally done through the Sine Law. In this work, a simple modification to the Sine Law is performed so as to prevent the tool gap from approaching zero at regions where the part contains a near vertical wall. Additionally, various multipass strategies regarding the design of the intermediate stages were trialed in an effort to increase geometric accuracy. Increasing the depth between subsequent stages of DSIF was found to provide the best results due to the accommodation of rigid body motion.
