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.

If you have any questions or want to discuss your design contact us. But for harder materials e g. Crca inside bend radius equal to 0 65 times of sheet thickness is also enough. Another way to determine the k factor is by following the rule of thumb.

Minimum bend includes minimum closeness of cutout to bend radius cold rolled steel 14 gauge 0 075 1 91mm. The material thickness will be measured in decimal form not by the gauge number. However it is important to know that this is just a broadly applicable rule of thumb you can follow for making bends in steel. First we must start with the k factor.

We are here to help. Recommended inside bend radius for sheet metal parts should be equal to material thickness. Choose a bend radius that matches your minimum bend. Sharp inside bend radius in sheetmetal parts can cause material flow problems in soft material and fracturing in hard material.

A cutout or the edge of your flange to your bend. Determine your minimum bend by measuring the distance from your closest feature i e. The bending angle is 90 sheet thickness 5 mm and the inside radius is 6 mm.
