Sheet metal folding

 Two methods of folding sheet metal are

  • Vee bending
  • Wiping die

V-Bending

 Sheet metal folding operations are carried out on a

press brake.

Bend allowance

 The bend allowance determines the amount of

material taken up to form the bend. A number methods exist

  • K Factor
  • Bend Table
  • Bend allowance
  • Bend deduction

Sample bend calculation

 Below demonstrates the

effect of neutral axis location (k factor) on the folded component.

Minimum Bend Radius

 Some material bend

mores easily than

  • thers. Shown below is

the min bend radius for different materials

Spring back

 When metal forming spring back must be taken

into account.
