Bending Theory and Press brake Technology; Part one of a two part series: Bending theory is a generally accepted set of guide lines which allow a feasable and repeatable method of predictable results to be articulated and/or proven in reality, and applied to forming technology as it is practised today. The most fundamental and easily controlled variables are the Inside Radius and the Material Thickness. In calculating an overall size for a part bent to 90 Degrees, I have found that one forumla serves best: Where I.R.= the inside Radius of the formed part, and M.T.= the material thickness, use.017453*I.R.+.0078*M.T.*90Deg.= The Flat arc length of the Neutral Axis of the bent material from one Tangent to the other, the Tangent being the point where the bend ends or begins.
