Good Thickness For Bending Sheet Metal

If you re bending 0 020 thick material use a 0 020 radius.

Good thickness for bending sheet metal. Wilson and fine 1981 studied the effect of sheet metal thickness ranging from 0 5 mm to 1 4 mm on fatigue performance. It just won t really be at maximum strength. 0 017453 x 90 x 0 020. To ascertain your k factor inside radius and material thickness expressed as a decimal you should use an bend.

Determine your minimum bend by measuring the distance from your closest. 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. Keep in mind that some metals are more brittle than.

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. When slotting sheet metal at the bend axis the material s average density in the bend region is decreased. First we must start with the k factor. There is no particular rule for how much the material should be weakened but as a rule of.

Finally bend the sheet up by hand to the angle desired. The bending angle is 90 sheet thickness 5 mm and the inside radius is 6 mm. Mark a bend line and place the sheet metal on the edge of your bench. 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 want a sharp 90 bend tap along the crease with a mallet. For most applications with stainless steel or aluminum you can get away with a zero radius bend on anything under 0 050 thick.
