help on conversion and subsequent development of sheet metal

[MORENO100]

Bye to all,
I use creo 2.0 and I look for a solution to my problem.
I have a folded sheet metal model (see image "folded model.jpg") that I would like to obtain laser cutting and bending.
my problem is that to get the development as shown in the attached file "develop.jpg" I have to make a gabola in defining the conversion feature.
the only way I've found to get the two "ripping connections" is by creating a temporary espionage laceration in this way:
- "gabola1.jpg" file set bending edges and edge laceration
- file "gabola2.jpg" I define the two "ripping connections"
- file "gabola3.pg" gates the edge laceration created in gabola1 and conclude the conversion
- and finally, as if it wasn't enough...., I also touched to bring the precision of the piece from 0.0012 to 0.00012 to get the development....

I hope that there is a more "official" method to solve my problem, perhaps allowing me to set up and view the corner drains.

p.s. I also attach the model "example_lamiera.prt"

thanks for the attention and good gioranta to all

the question arises spontaneously, because you started from a solid "tasted" and converted, instead of starting from a real sheet?, you would have less feature and more overall efficiency.

hi 320i s, because by experience I consider this method more versatile..... easier and faster to manage in modeling phase.
I am a self-taught fool, I admit that I don't know the correct way of using the program and that's why I want to compare myself to who is more experienced than I am.
I'd ask you to attach a model of how you would model it, but I see you use creo3.0...:frown:

 

[320i S]

the basic problem is this: you are trying to develop a form that I create identifies with a continuity of surface even where you meet the main walls with the smaller walls.
It is likely that with a light shape, the model manages to develop, but it is still a non-real situation, in practice I create it not as a piece of die-piega, but a printed one.

If you want to make the sheet in the dish, you must first make an extrusion of sheet (the two main sides), put the walls with the wall or flange command, develop, cut the corners because they do not overlap and fold.
so you have the correct modeling.

thanks 320i s for the answer, always very punctual and competent.
but is there someone else who can take my initial problem and give me his best answer?
two experiences are always better than one.
Thank you.

hi moreno100,
Look if you like my solution.
during the conversion in sheet metal I created the folds, then 2 tears.

Hello jambo,
I opened your file but it is not clear to me.... compared to my file the only difference I know is that in the option tab of the conversion feature you set "adjacent squirrels" instead of "all edges."... it doesn't seem to me that in doing so I can exploit a more "official" modeling procedure, I should still run the steps of the gabola from me above reported.... what does it escape me?

 

[JAMBO1970]

Moorish, you miss the fact that I did not use any "gabola", I simply used the conversion command
sheet metal in the system, i.e. creating all folds and 2 tears.
in your file if you open the feature sheet conversion there are no folds in the model, but only tears.
available for further clarification.

good morning forum,
I know that it is not correct to reopen old posts and fit tightly into other discussions and I also apologize in advance, but this is very similar to what I am about to ask you.
I use wf3 and I never had the opportunity to make a project "lamiera".
Now I have to do a favor to a group of people and make a memorial plaque that practically involves a conical displacement with a perforated epitaph.
all right here and I'm done, what I can't do is bring back the development on a plan so that I can then export a dwg or dxf to give the laserista for cutting.
thanks to all

Hi.

if you attach the file I can give an eye ... otherwise it is difficult to give you advice, depends on how the piece was modeled.

 

[Arturo M.]

That's very kind.

 

[DANI-3D]

with wf5 is so, but if I don't remember badly also with wf3:

insert > bending > flattening
regular
> fixed geom and select the edge as indicated in the image
> radr geom schegli flattened all

a little confirmation and the game is done.

 

[Arturo M.]

Tonight I try, thank you very much

 

[Arturo M.]

Thank you, I sent the laser cut file, they opened it right away, they cut, shit, everything done.
thanks again for the tips

Please. I'm glad you were helpful.
