The Effects of Forming Angle on the Geometry Accuracy and Mechanical Properties of Al-Li Alloy Truncated Pyramids by Single Point Incremental Forming

In this study, single point incremental forming (SPIF) of Al-Li alloy sheets under different angles are studied via both experimental methods and numerical simulations. The effect angle on the geometric accuracy SPIFed component is studied. simulation results show that higher angle, lower stress at corner, leading to better geometrical accuracy, which also experimentally validated. It found high leads mechanical properties component.
