How to calculate the air-formed radius of different bend angles

July 21, 2015

By:

Using the 20 percent rule works well when calculating the floated radius in an air form, but what about the radius at different bend angles? To calculate this, we start with geometry to find the arc length and radius at different bend angles. We then manipulate these results by factoring in real-world bending conditions.
