Abstract: Modern sheet metal forming technique known as incremental sheet metal forming (ISMF) enables the production of 3D complicated components made of thin sheet metal utilizing a CNC milling machine. Any manufacturing process must take the surface quality into consideration. Therefore, this work focuses on the residual stresses that emerge from changing the forming parameters (feed rate, side step, and speed) for products made using the single point incremental forming (SPIF) technique. On aluminum sheets (AA1050) with a thickness of (1) mm, practical tests to construct pyramid-like shapes have been carried out to assess the surface quality. In addition to three levels for each side step and feed rate, three other types of parameters were used in this study to produce larger residual stresses than other factors. The influence of these factors on one slope angle was examined, and it was discovered that residual stresses increased as feed rate and side step and values increased. The analysis of variance (ANOVA) approach revealed that the side step with (65.42%) for slop angles (=60°) is the most important parameter. [ABSTRACT FROM AUTHOR]
