formulas and tables that are commonly encountered or particularly useful in tube-bending under three sections: Bending Formulas, Geometric Formulas, and Conversion Formulas. Much of this information is generally applicable to tube-bending without regard to method, but the focus is upon that mathematical information that is useful in setting up a rotary-draw tube-bending machine.
