Description: The standard bending operation involves moving the punch (up or downward) and deforming the sheet over a bend radius ri. A more advanced method is bending with counter pressure, also known as down-flanging, where the bending occurs with the use of a counter holder. This has the benefit of avoiding folds, in addition to reducing mechanical springback and tearing. This interactive animation schematically shows the conventional bending and down-flanging.
