Default Radius Calculations based on tooling

I am fairly new to sheet metal and everywhere I look online i can find bending calculators for bend deduction and so on. I understand this concept but what I am having a difficult time with is the radius input as the radius is based on the width of the die opening....how or where can I find a calculator or calculations to figure out with material X and Y degrees using die opening Z the predictable radius output will be...?. Any help at all would be greatly appreciated. Thank you

Default Punch

Hi Altona, unless your coining the die is not as important as your punch. For nice precision
work you should be air forming. The die determines speed and leverage of your bend, the
punch the radius.
