To make large number of parts in automotive, aerospace, and appliances industries, sheet conventional metal forming processes, such as stamping, are used. However, for small number of productions, novel flexible manufacturing processes, such as incremental sheet forming (ISF) must be utilized to decrease the production costs. Studying the process parameters in ISF process such as, the toolpath, step size, tool size, feed rate, lubrication, and wall angle is essential as they are affecting the formability and deformation behavior of this process. The purpose of this study was to investigate the effect different types of toolpath, such as z-level (profile) and helical (spiral) to form a truncated-conical geometry in simulation of the single point incremental forming (SPIF) of AA7075-O. A detailed comparison of these tool paths' predictions was made with respect to the effective plastic strain distribution, part thickness, tool force and moment.
