The results of sheet metal air bending process are still very difficult to predict, despite the
high level of automation introduced on the bending press by the computer numerical control.
The air bending process results are related to the obtained angle after springback and to the
elongation of the component, which can be measured through the so-called bend deduction
parameter (BD). While the prediction of the springback phenomenon is largely discussed in
the literature and several prediction models are available, the bend deduction is often …
