The tool can calculate the required bending force for bending aluminum, stainless steel, mild steel, and Weldox® or Strenx® high-strength steels. Material Alluminio AL99.5-1050A Acciaio S275 Acciaio S235 Inox AISI304 Strenx® 700 (Weldox® 700)Understanding Bending Force. Bending force, also known as the bending moment or flexural strength, is the force applied to a metal sheet to induce a permanent change in its shape through plastic deformation. The process involves compressing the material on one side (the inside of the bend) while stretching it on the other (the outside of the bend).
In bending operations, bottom bending is used frequently at the bottom dead center in order to stabilize the shape. An extremely large force is required in bottom bending depending on the amount of bottoming. The size of that force is considered to be 5 to 10 times the free bending force. (1) Bending force for V-bending (See Fig. 1)

The following illustration shows the equation / calculation for determining the bend line to mold allowance when forming sheet metal. . For instance, if the sheet metal to be bent is mild steel, with a thickness of 4mm and a bending length of 3.2m, the theoretical width of the bottom die opening should be 8 times the thickness, which is 32mm. Input these figures into the calculator above (remember the units are in mm), and we get a value of 106.12 Ton. This means you’ll need a minimum bending . Factors Influencing the Minimum Bend Radius. The minimum bend radius of the sheet metal is affected by several factors, each of which is of specific importance in determining the most desirable degree of bend that would prevent collapse or paper deformation. tAng factors include:. Material Type: Different materials have varying levels of ductility and tensile strength, . Use the sheet metal module or tools in the software: Most 3D CAD software provides related tools and functions for sheet metal design. For example, Creo offers a variety of methods for controlling the unfolded dimensions of sheet metal, including the modeling and unfolding methods of large arc sheet metal parts, bend deduction method, etc .
When the sheet metal is bent the inside radius pulls the edge of the material away from the apex of the bend. Because this is a geometrical function it does not change with a metal’s K-Factor the way Bend Allowance and Bend Deduction do. The Inside Setback is closely related to, but should not be confused with, the Outside Setback. The below .
To understand why the K-factor cannot exceed 0.5, it’s crucial to comprehend the concepts of the K-factor and the neutral layer in sheet metal bending. Understanding Sheet Metal Bending. Sheet metal bending involves creating a controlled deformation to form a . Complementary bend angle. Simplified to an equation you can punch into any calculator, and using 0.446 as the K-factor, we have: BA = [(0.017453 × Inside bend radius) + (0.0078 × Material thickness)] × . Complementary bend angle. At this point, the formula for bend allowance has incorporated the shifting of the neutral axis. Learn how to determine the optimal V-Die opening or Die Size for sheet metal air bending. Skip to final Equation: [4:50]Believe it or not, there is a scien. T s
- How the difference between the punch and die angle influences the bending force is very important. When it is increased, the bending force is decreased. This effect is greater in thinner material and material with a larger hole percentage. - Bending forces in sheet metal components with holes on bending surfaces can be determined by Eq. (4).
