Popis:	The present article focuses on single point incremental forming (SPIF) process with dummy sheet. Influence of process parameters namely dummy sheet thickness, tool size, step size, wall angle and feed rate on minimum thickness of formed parts is investigated. After experimentation and analysis, it is found that the wall angle, tool size, dummy sheet thickness and step size are significant parameters. Based on the analysis mathematical model is developed to predict minimum thickness of formed part. Further optimisation of process parameters is performed using desirability function in order to maximize the minimum thickness. In SPIF process with dummy sheet, it is observed that the variation in wall thickness is small and overall wall thickness distribution along the depth of formed parts is almost uniform. Also, wall thickness distribution obtained is close to the value predicted by sine law.
