The bend allowance and bend deduction are two measures
that relate the bent length of a piece of sheet metal to the flat
length.
The bend allowance describes the length of the

After a bending operation, residual stresses will cause
the sheet metal to spring back slightly. Due to this elastic recovery,
it is necessary to over-bend
the sheet a precise

Calculate the required force to bend a piece of sheet
metal using V-bending, a process in which a V-shaped punch presses the
sheet into a V-die.
The bending force can be

Calculate the required force to bend a piece of sheet
metal using wipe bending, also called edge bending. In this process, the
sheet is held between
