Tube bender operators could rely on complex mathematical formulas and rules of thumb, but it’s much quicker to use a tooling chart. This sort of chart lists the two main bending criteria, D of bend and wall factor, on the X and Y axis, respectively. However, these charts have just two axes, and usually are based on bending mild steel to 180 degrees. Tube bending comprises many more variables, materials, and bend angles. Knowing how to make adjustments to compensate for additional factors is critical for successful bending.
