Small and medium volume complex parts can be produced by dieless forming inexpensively using this method. In this study, maximum forming angle in truncated pyramid geometry formed from Al-1050-H14 sheet metal without fracturing has been experimentally investigated. Also, wall thickness variations of the formed metal have been measured. The experimental studies were carried out on CNC vertical milling machine by using negative incremental forming. According to the experimental results, maximum forming angle has been obtained as èmax = 61o.}, number={2}
