An experimental investigation of springback of AA6061 aluminum alloy strip via V- Bending process

Abstract

Springback is one of the common geometrical defects found in the sheet metal forming process. Aluminium alloy with high content of magnesium such as AA6061 is preferred for their high formability limit, but commonly springback becomes a drawback. In this study, springback behaviour of the AA6061 will be observed. The effect of length, thickness and bend angle to the springback pattern was investigated and the result depicted that springback is more significant to thickness and bend angle, while the length gives less effect. © Published under licence by IOP Publishing Ltd.
