Bend Radius Sheet Metal Thickness

But for harder materials e g.

Bend radius sheet metal thickness. We are here to help. You will need to know your material thickness mt the bend angle b the inside radius ir and the k factor k. Choose a bend radius that matches your minimum bend. Another way to determine the k factor is by following the rule of thumb.

Recommended inside bend radius for sheet metal parts should be equal to material 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. We want to know the final length of the detail. First we must start with the k factor.

If you have any questions or want to discuss your design contact us. However it is important to know that this is just a broadly applicable rule of thumb you can follow for making bends in steel. Determine your minimum bend by measuring the distance from your closest feature i e. The material thickness will be measured in decimal form not by the gauge number.

The bend allowance formula takes into account the geometries of bending and the properties of your metal to determine the bend allowance. The bending angle is 90 sheet thickness 5 mm and the inside radius is 6 mm. Crca inside bend radius equal to 0 65 times of sheet thickness is also enough.
