The basics of applying bend functions
Why calculate values such as bend allowance, outside setback, and bend deductions? Because sometimes you will need to work your way around a bend on a print, and you may not have all the information you need to complete a flat pattern.

K-factor is a ratio of location of the neutral line to the material thickness as defined by t/T where t = location of the neutral line and T = material thickness. The K-Factor formulation does not take the forming stresses into account but is simply a geometric calculation of the location of the neutral line after the forces are applied and is thus the roll-up of all the unknown (error) factors for a given setup.

Laminated press brake idea. New?
The several shop press/ press brake threads recently got me inspired to start thinking about my own needs. I have a HF 20 ton press with my own press brake...
In air-bending, the inside radius of a bend is determined by the width of the die V opening. Occasionally, either for aesthetic or practical reasons, a radius is required which is smaller than can be achieved by air bending.Technology is described in the image

Bending Basics: How the inside bend radius forms
Press brake guru Steve Benson describes how the method of bending—coining, bottom bending, or air forming—is very influential on how an inside bend radius is achieved.
