Bend Radius Sheet Metal Thickness

So if the metal plate is 75 thick you would multiply 4 x 75 3 so your minimum inside bend radius would be roughly 3 times the thickness of the material in this case or 2 25.

Bend radius sheet metal thickness.

The bend allowance formula takes into account the geometries of bending and the properties of your metal to determine the bend allowance. Sharp inside bend radius in sheetmetal parts can cause material flow problems in soft material and fracturing in hard material. First we must start with the k factor. Minimum bend includes minimum closeness of cutout to bend radius cold rolled steel 14 gauge 0 075 1 91mm.

We want to know the final length of the detail. But for harder materials e g. A cutout or the edge of your flange to your bend. Crca inside bend radius equal to 0 65 times of sheet thickness is also enough.

Determine your minimum bend by measuring the distance from your closest feature i e. Another way to determine the k factor is by following the rule of thumb. You will need to know your material thickness mt the bend angle b the inside radius ir and the k factor k. We are here to help.

The bending angle is 90 sheet thickness 5 mm and the inside radius is 6 mm. Recommended inside bend radius for sheet metal parts should be equal to material thickness. Choose a bend radius that matches your minimum bend.
