now hotwire Foam cutter. profile XY UV shoudt be considert to bring a good gcode to the mashine from the WB not over path
I agree. Apart from wire-cutting foam cores for wings, what would be the purpose of this workbench ? Yes, OK, you could also cut — CNC or laser — all the ribs, but then you need some way to customize the ribs, to place servos, cable pass-throughts, connections ... all the while keeping the parametric aspect of the problem.
Also, how does this behave with airfoils from different families (Eppler, Selig, Hepperle, NACA...) ?
I'm sorry to say it so bluntly, but importing a bunch of X-Y points into FreeCAD is not enough to make a useful workbench.
Thank you for your comment, I agree that the workbench at this stage is not enough to make a useful workbench, but after a first try on my ASK13 (some pictures below), I think that the foundation of such workshop is to properly manage ribs in parametric form.
After that first step I will work on the wing with two approach :
- produce the wing envelope and make cuts to generate all the ribs, the first step of this method is implemented, and you can generate the wing, change the profil of ribs if you want and view the result. The next step is to be able to make a customization in order to integrate the elements of a wing like the servos, the wing key, the lightening of the ribs, etc ...
- produce directly all the ribs
Finally the idea of communicating at this stage of development is to collect the needs / opinions of the greatest number and to orient developments towards the most useful functions.
be free to go beyond doubts and express your desires and we will see if it is feasible or not ...
