The purpose of this study is to investigate the effects of process parameters (tool diameters, wall angle and step size) on geometric accuracy during forming pyramid shape using computer numerical control (CNC) milling machine. Taguchi orthogonal array (L9) was used to design the experimental work and the results were analyzed using ANOVA package in Minitab 2017. The results shows that geometric accuracy increase as tool diameter and step size are decrease while it increase with wall angle increase. Two type of error was found sheet bending error (eb) and spring back error (es). Tool diameter have the highest effect on geometric accuracy followed by wall angle and step size.
