A Review of Experimental study of Springback Determination of Ferrous Sheet Metals in an Air Bending

The air bending process can be erroneously considered as an easy understanding process without complication, but this is a false judge. Several parameters have to be considered in order to avoid precision problems: material and process parameters. Among them, springback phenomenon has a significant role. Traditionally, springback has attempted to be expressed in handbook tables or in springback graphics. But both ways of giving expression to springback amount show shortcomings. This paper presents new springback graphics for air vee bent sheet metal parts. The developed experimental procedure has two main stages
