## What is Airbend Lite?

Airbend Lite is a tool that will perform calculations for bending precision sheet metal on modern press  brakes.  There are many apps for calculating standard sheet metal bending information, but what makes Airbend Lite unique is that it will provide bending calculations specifically for air bending.  (Airbend Lite will also provide the standard bend information if the "Bend Type" is set to "Bottom Formed")

Inputs:
  Material Type (Cold Rolled Steel only)
  Material Thickness
  Bend Type
  Bend Angle (90 degrees only)
  Inside Bend Radius
  V-Die Radius
  V-Die Width

Outputs:
  Actual Bend Radius
  Bend Deduction
  Bend Allowance
  Setback
  Minimum Flange

Output does not have units.  As long as all entries are consistent (millimeters or inches) the output will match.

You can mix millimeters, feet, fractions, etc. by using math formulas as long as the formulas evaluate to the same units.
E.g
2.5 millimeters to decimal inches (2.5 / 25.4)
3 feet to decimal inches (3 x 12)
3/16" to decimal inches (3 / 16)
.118" to millimeters (.118 * 25.4)

Any feedback or requests for additional calculations or information is greatly appreciated.
