Bending steel sheet metal.

Most sheet metal materials will conform to the calculations. This page also includes a link to a on line sheet metal bend allowance calculator. To clamp efficiently lay your sheet metal on the top surface of your straightedge with the drawn line perfectly aligned with the outside edge of the sheet metal. For most applications with stainless steel or aluminum you can get away with a zero radius bend on anything under 0 050 thick.

Choose a bend radius that matches your minimum bend. Sheet metal calculator bend allowance equations and calculator. Hot metal forming offers tighter bend radii in high carbon steel in degrees that might break the material in cold forming. Determine your minimum bend by measuring the distance from your closest feature i e.

Clamping your sheet metal to the straightedge is a must. As an example if you want to bend 24 gauge sheet metal at a 90 angle the calculation would be. This is done through the application of force on a workpiece. 0 017453 x 90 x 0 020 0 33 x 0 024 0 0438558984 inch bend allowance keep in mind that some metals are more brittle than others.

Otherwise the sheet metal is almost certain to shift as you bend it resulting in a bad bend. If you re bending 0 020 thick material use a 0 020 radius. The following illustration shows the equation calculation for determining the bend allowance when forming sheet metal. Mild steel 1 brake shear slip roll 1 metal forming 1.

Sheet metal bending methods design tips k factor bending is one of the most common sheet metal fabrication operations. A cutout or the edge of your flange to your bend. Bending a brittle metal beyond its limits could cause the metal to snap and break. The process delivers highly accurate forming maintenance of thickness and tremendous finished component strength.

Also known as press braking flanging die bending folding and edging this method is used to deform a material to an angular shape. Stainless steel 1 20 ga. Mild steel 1 16 ga.
