What is V bending?
The most common method is known as V–bending, in which the punch and die are “V” shaped. The punch pushes the sheet into the “V” shaped groove in the V-die, causing it to bend. If the punch does not force the sheet to the bottom of the die cavity, leaving space or air underneath, it is called “air bending“.
