sheet metal development calculation bent with inventor

[un_poldo]

If I have a thick sheet and known material and want to make a 90° fold, to calculate the exact development, the workshops where I go put the face data in the cnc of the machine and the machine automatically calculates the exact development.

I explain, I have to make an angle with a side of 30 mm and the other of 20 mm, the decoy is not necessarily a 50 mm sheet but will be little more than 50 if I use stainless steel, or little less than 50 if I use fe (equal thicknesses obviously).

inventor (I don't know how to use) can tell me these parameters that otherwise I would only know after consulting the workshop? and if yes, what degree of realisticity do they have?

the beauty of inventor is that from the bent profile that has one or more folds and converts it into flat (before you have to set in styles the thickness and type of material) automatically calculates the development of your piece!
personally since I send to the workshops the development of the piece (which then I have to convert to dxf for laser cutting), the pieces that fall into the company already finished with folds and all the rest have always been well ready for assembly!
a lot of time saved when with the 2d I had to go to add or remove the various ironings according to the type of material!

I imagine that you mean the inner sides then the "old" are added the inner sides precisely... to get this value you have to set the "k" factor as 0.253, playing with this value, you will have extensions or shortenings of the flat model.
then to each material and thickness you can set a different k factor in function to tests that you will carry out in the workshop.
then if you want to refine even more you can create fold tables that allows you to act on different beams and angles of fold.
