Analysis of forming forces at SPIF using Taguchi method

Incremental sheet metal forming process has seen one of the highest increases in diversity last years. Single point incremental (SPIF) become more attractive due to multiple benefits it possesses over other conventional cold processes such as deep-drawing. However, yet arise large-scale industrial implementation because its drawbacks high production time and low accuracy, which lead prototype production. A very important aspect for this manufacturing is analysis form-ing forces terms energy especially when using robots. The aim paper investigate influence material vertical step forces. Thus, aluminum steel sheets with a thickness 0,8mm were incrementally deformed truncated cone an angle 60°, at depth 30mm. Experiments performed KUKA KR 210-2 robot allows measure piezoresistive sensor. After performing Taguchi method, can be observed that influence.
