Fighting springback in profound radius bends

September 17, 2001

By:

When bending sheet metal, three terms apply to the radius of the bend: sharp, radius, and profound. A sharp bend has a radius less than 63 percent of the material thickness. A radius bend has a radius between 63 percent and 10 times the material thickness. A profound radius exceeds 10 times the material thickness and an entirely new set of rules apply. This article presents those rules.
