Air Bending Calculator
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 calculated from the sheet thickness, bend length, material and a safety factor.
The die ratio will be used to calculate the die opening, which is typically 6 to 10 times the sheet thickness.
The calculated tonnage can be used for the selection of a machine, such as a press brake, to perform the bending operation.
The factor of safety in most cases will be 1.
We also have Bend Allowance, Deep Drawing Force, Spring back and Wipe Bending Force Calculators.
Enter your sheet thickness and length then select your material type and finally enter a safety factor, units can be selected as required.
