I am trying to make a spreadsheet for our shop.
We are not allowed to spend time and material on trial and error on test bending. We can only use the in built software in the bending machine to calculate cut measures.
But as we experienced it is not always right and, neither does it give us any information the software uses to calculate k-factor.
So is there any way, by using a variety of formulas, depending on the bending angle, to make a spreadsheet with near accurate k-factors? Or if any have any spreadsheets made out already that works good? It have to be in mm, because those I have forund has been in inches and it will come out wrong if I try to fill in data in mm.
