### What is inside bend radius and why is it important?

Bend Radius- As a rule, inside bend radius should be equal to material thickness. When the radius is less than recommended, this can cause material flow problems in soft material and fracturing in hard material.

of the panel and reduce the amount of vibration and noise in the sheet. Most fabricators of sheet metal parts will require a minimum bend radius on formed objects. The minimum bend radius should be a minimum of ½ of the material thickness, so if the material is 18-gauge or 0.048 thick, then the inside radius would be 0.024,

Bend Radius - As a rule, inside bend radius should be equal to material thickness. When the radius is less than recommended, this can cause material flow problems in soft material and fracturing in hard material. Bend Relief - When a bend is made close to an edge the material may tear unless bend relief is given. Figure "A" shows a torn part.
