In this study, the effects of annealing and key process parameters on the incremental forming of Al1050 aluminum sheets were investigated. By varying parameters such as tool rotational speed, tool feed rate, and vertical step size, the aim was to enhance the incremental sheet forming of a truncated pyramid with a rectangular base. Numerical simulations were carried out using Abaqus software, and experimental tests were also conducted. The results showed that the T4 annealing process reduced sheet damage by 24% and significantly decreased cracking after 15 mm of stretching compared to non-annealed samples. Moreover, lower values of tool rotational speed, feed rate, and vertical step size led to improved forming quality of the workpiece.
