Single point incremental forming (SPIF) is a new in novative and feasible solution for the rapid protot yping and the manufacturing of small batch sheet parts. In the pr esent study experiments were conducted to analyze t he effect of process parameters on the formability of commercial aluminum alloy AA1100. Major process parameters li ke Wall angle,Step increment,Feed rate,and Spindle speed,are set at three levels and experiments were desi gned by using the Taguchi method to get the two response paramete rs,wall thickness and surface finish. Analysis of variance shows that surface roughness depends on step increm ent by 64.19 % and wall angle by 17.23 %. For thick ness reduction only wall angle (99.79 %) is responsible. For achieving better surface finish we need to con trol wall angle,step increment and feed rate while for thickness re duction we have to control only wall angle. https://www.ijiert.org/paper-details?paper_id=140486
