Minimum Recommended Bend Radius Chart from American

Minimum Bend Radii The minimum bend radius data shown in these charts is measured to the inside of the bend.The bend radii listed are standard minimum if manufacturing for aircraft and aerospace applications.Since commercial sheet metal bending can be done with less concern for stresses caused during forming operation,the radius can be near zero for thin sheet metal.Minimum Bend Radius Calculator in sheet metal or plate.Minimum Bend Radius.What is the minimum radius? It is the smallest inside bend radius that you can place in a piece of material before the tensile forces on the outside of the bend begin to tear the grains in the material apart.It is normally expressed in terms of multiples of the material thickness,e.g.1t,2t,etc.Making Straight Line Bends - Aircraft Metal Structure To the radius of bend (R) add 12 the thickness of the metal (12T).This gives R + 12T,or the radius of the circle of the neutral axis.[Figure 4-128] Compute the circumference of this circle by multiplying the radius of the neutral line (R + 12T) by 2 (NOTE = 3.1416) 2 (R + 12T).
