Sharp inside bend radius in sheetmetal parts can cause material flow problems in soft material and fracturing in hard material.
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.
Choose a bend radius that matches your minimum bend.
But for harder materials e g.
You will need to know your material thickness mt the bend angle b the inside radius ir and the k factor k.
Recommended inside bend radius for sheet metal parts should be equal to material thickness.
The material thickness will be measured in decimal form not by the gauge number.
Determine your minimum bend by measuring the distance from your closest feature i e.
Crca inside bend radius equal to 0 65 times of sheet thickness is also enough.
We want to know the final length of the detail.
If you have any questions or want to discuss your design contact us.
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.
A cutout or the edge of your flange to your bend.
We are here to help.
Another way to determine the k factor is by following the rule of thumb.
