Bend Radius Sheet Metal Thickness

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

Bend radius sheet metal thickness. The material thickness will be measured in decimal form not by the gauge number. If you have any questions or want to discuss your design contact us. Sharp inside bend radius in sheetmetal parts can cause material flow problems in soft material and fracturing in hard material. Determine your minimum bend by measuring the distance from your closest feature i e.

However it is important to know that this is just a broadly applicable rule of thumb you can follow for making bends in steel. You will need to know your material thickness mt the bend angle b the inside radius ir and the k factor k. But for harder materials e g. The bend allowance formula takes into account the geometries of bending and the properties of your metal to determine the bend allowance.

First we must start with the k factor. A cutout or the edge of your flange to your bend. Recommended inside bend radius for sheet metal parts should be equal to material thickness. We are here to help.

We want to know the final length of the detail. Choose a bend radius that matches your minimum bend. The bending angle is 90 sheet thickness 5 mm and the inside radius is 6 mm.
