Good Thickness For Bending Sheet Metal

We want to know the final length of the detail.

Good thickness for bending sheet metal. There is no particular rule for how much the material should be weakened but as a rule of. Keep in mind that some metals are more brittle than. Next place the wood parallel and slightly behind the bending line. If you re bending 0 020 thick material use a 0 020 radius.

Finally bend the sheet up by hand to the angle desired. For most applications with stainless steel or aluminum you can get away with a zero radius bend on anything under 0 050 thick. When slotting sheet metal at the bend axis the material s average density in the bend region is decreased. Another way to determine the k factor is by following the rule of thumb.

As an example if you want to bend 24 gauge sheet metal at a 90 angle the calculation would be. The sheet metal bending height should be at least 2 times the thickness of the sheet metal plus the bending radius that is h 2t r. Determine your minimum bend by measuring the distance from your closest. It just won t really be at maximum strength.

First we must start with the k factor. The bending angle is 90 sheet thickness 5 mm and the inside radius is 6 mm. Wilson and fine 1981 studied the effect of sheet metal thickness ranging from 0 5 mm to 1 4 mm on fatigue performance. Clamp the wood on top of the metal to the workbench.

0 017453 x 90 x 0 020. In other words if you re bending 1 8 sheet use a tool with a 1 8 radius to form the inside of the bend.
