A metal sheet of 6 mm thickness is to be bent at bend radius of 10 mm and the bend angle is 90°. In second case, a sheet of 4 mm is taken to bend for same radius and angle.
1
Bend allowance for first case (t = 6 mm) is 18.8 mm
2
Bend allowance for second case (t = 4 mm) is 18.8 mm
3
Bend allowance is same for both cases
4
Bend allowance does not depend on bend angle
