The bend deduction is the amount the sheet metal will stretch when bent as measured from the outside edges of the bend. These sections are located at the edges.

The following illustration shows the equation calculation for determining the bend allowance when forming sheet metal. It is important to make sure that the sheet is properly pushed onto the wipe die. 0 017453 x 90 x 0 020 0 33 x 0 024 0 0438558984 inch bend allowance. Economy sheet metal benders make bends up to 90 in metal sheets.

The slack between the wipe die and the punch plays an important role in getting a good result. How to bend sheet metal without a brake in 4 different methods with minimal or homemade tools.
