One of my few C ++ applications. I use the program on a daily basis at work as an aid in the preparation of sheet blanks for the free bending process on press brakes.
The application has a very simple interface consisting of a group of radio buttons, three text fields and basically that's it ... 🙂
If you are interested in some theory about the bending process, please visit the following pages:

https://www.trumpf.com/pl_PL/rozwiazania/zastosowania/giecie/ - described bending process and its varieties.

The program calculates by how much the blank should be shortened to obtain an element with the assumed dimensions after bending. The formulas from DIN 6935, which can also be found, were used to determine these values here.
From the programming point of view, the application was written in C ++ using C ++ Builder by Borland.
If you want to test my application, you can download the zipped .exe file here .
