Abstract Scope |
Multi-stage incremental sheet forming (MISF) is a novel manufacturing process in which complex 3D shapes can be formed through a series of forming processes using generic forming tools. This study aims to explore effects of ultrasonic vibration on the MISF process and reveal the deformation mechanism based on the microstructure analysis. First, the initial, intermediate and final shapes were designed for the MISF in which the wall angle and depth deviation of the adjacent stage should be decreased. Then, a series of experiments for ultrasonic-assisted ISF was performed during which the strain evolution was recorded by the digital image correlation system. Furthermore, the microstructure evolution (e.g. grain size, misorientation and texture) of the formed parts under different forming conditions and forming stages was examined through the optical microscope (OM) and the electron back-scatter diffraction (EBSD). Through this study, further insight into the deformation mechanism during the ultrasonic-assisted MISF was provided. |
