Good Thickness For Bending Sheet Metal

Another way to determine the k factor is by following the rule of thumb.

Good thickness for bending sheet metal.

0 017453 x 90 x 0 020. We want to know the final length of the detail. The bending angle is 90 sheet thickness 5 mm and the inside radius is 6 mm. 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. If you re bending 0 020 thick material use a 0 020 radius. When slotting sheet metal at the bend axis the material s average density in the bend region is decreased. Mark a bend line and place the sheet metal on the edge of your bench.

Keep in mind that some metals are more brittle than. There is no particular rule for how much the material should be weakened but as a rule of. To ascertain your k factor inside radius and material thickness expressed as a decimal you should use an bend. First we must start with the k factor.

For most applications with stainless steel or aluminum you can get away with a zero radius bend on anything under 0 050 thick. Finally bend the sheet up by hand to the angle desired. Determine your minimum bend by measuring the distance from your closest. If you want a sharp 90 bend tap along the crease with a mallet.

Next place the wood parallel and slightly behind the bending line. 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.
