double curvature of sheet metal, how? please help

dear caders,

in the modelling of a small plane for educational reasons we are encapsulated in this part here in generative sheetmetal (1mm thick) :
PDF Architect  - [cri_cri_planos - 00037]_2013-07-02_10-55-29.webpI tried first the "bruto" method of double bending in sequence with this result:
brute.webpthen I went to realize it but the only way is to bend it perpendicularly to the long side, then create the walls on the sides. where there is the elbow on the long side I remain 2 openings and also irregularities
CATIA V5 - [Product1]_2013-07-03_07-52-22.webpDo you have any advice? I saw some examples of sheet metal in double curvature. how would you solve the problem?

greetings and thanks
 
I have done more experiments and the best solution is to ensure that the cut is straight and then creating a flange with propagation. . .
brute.webpI receive a warning that I still need to understand.

how would you deal with the problem? Thank you.
 
the piece you are trying to shape is not a folded sheet but printed (at least from pdf you understand this).
the bottom problem lies in the rays that for the sheetmetal are folded.
you can try with print features.
otherwise you can shape your sheet as a surface and feed it to the feature "hopper", so you will have the opportunity to have the explained.

if you need further help do not hesitate to ask!
 
Thank you mrwolverine,

I tried mold (imbutitura) and it does not allow me to control the lower surface which is bent readrmete (just set only one floor).

stamp.webpCATIA V5 - [Product1]_2013-07-08_08-19-40.webpI therefore try the solution "hopper" . the problem seems to be as rightly you say that the bending operations are thick constant while the double curvature that I look for require the material to iron.. .

greetings
 
Hello Michael

your example is solved with the sheet-metal function for the surface developer, the icon is that of the cone trunk.

the function allows you to develop a model made a superfice.
clearly in making the surface you have to take into account the internal or external folds, the system will then calculate the feature both developed and folded taking into account the material thickness.
If I can make you have a hedgehog.
 
thanks ferrezio master of axe on catia! ;)

I think this is the most elegant solution: hopper starting from the surface. the piece is solved 100%

place images to store know how and honor the master!

I would like to know if there is a way to treat sheet printed in autodesk inventor (as the sheet indicated) so as to have development
