Define Bending and also explain their types?

Bending

Bending is a metal forming process in which a force is applied to a piece of sheet metal, causing it to bend at an angle and form the desired shape.

Bending Types :- 

Two common bending methods are:

V-Bending

Edge bending

V-Bending:  

The sheet metal blank is bent between a V￾shaped punch and die.

￾ Air bending: 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“.

Edge or Wipe Bending:

Wipe bending requires the sheet to be held against the wipe die by presses against the edge of the sheet that extends beyond the die and pad.

The sheet will bend against the radius of the edge of the wipe die.
