normal cutting sheet for laser cutting

[PLOTTER83]

Good morning to all,
I had to ask you the following question.
how do I make a normal cut just through a fold or a calandrate piece, keeping the face of the sheet thickness perpendicular to the other faces? I explain: if I make a cut that is not perpendicular to a face of the sheet it is cut me by traverse, therefore the flat model for laser cutting is not good. Forgive ignorance, but I am a former solidworks designer and on this software was much easier...I attach a file (inventor 2010)
thanks andrea

look at this::smile:
As you see, there's no way to invent who knows that than solidworks.

compared to solidworks or solid edge yes, there is to invent......
This hole for example I can't "normalize it"

What do you mean by normalizing it?

 

[ipotemusa]

What do you mean by normalizing it?

must be "normal" to the face (perpendicular)
as it comes is not the real, development is wrong

If you really have your sheet and want to make a hole whose walls are perpendicular to the face of the sheet, I suppose you will make this hole on the sheet before bending it, not after, (even because, unless you use a laser-tube, I would like to see how you do "after").
construction of the calandrate, then drill it and then thicken it to the desired thickness.
In inventor, I don't know how in swk or others, but I suppose there's probably a special command in sheet metal. . .

As I did in the example it is circular when it is calandrated, so the tube I have to put passes, but it is incorrect in the development (top laser cutting).
both in sw ke in if there is a special command, only on the sheet environment.
from developed I can not add holes, because I find the tubes (to be recalculated) in the assembly.
or "refuse" from each hole or I don't know how to do... sin, however, I have found many qualities in inventor, but this is a big sin for those who make sheet metal, especially if they fall.

you should act as in reality, more or less, make your cylinder calandrate, develop and misuri, turn back, eliminate the development and design, create a sketch with a rectangle with the measures of the developed preceded, the thicknesses with the face flat command, create the hole where you need, converges in normal part for the moment, create a radius to diseganate a line of the plate

@ tarkus: thank you, I ignored the existence of the supestrusion command. Can you tell me where this command is? (extrusion)

@ ipotemusa: I quote the solution that suggested tarkus. I've tried more and I have to say it's the quickest.

speaking in general, I think that self-desk inventor on the plates should still make giant steps. should insert an option that tells the software to cut normally compared to the thickness of the sheet and also the possibility to obtain a sheet from a solid emptied.

Good start of the week!

the supestrusion or suprivoluzione can be found in the same extrusion or revolution commands, you have a casellin (bottom left in the dialog box) to choose if you want a solid or surface. . .

... should insert an option that tells the software to cut normally compared to the thickness of the sheet and also the possibility to obtain a sheet from a solid emptied. . .

I don't know if with other software is easier, but these things can be done both.
to make a cut always normal to the sheet, you do a sketch on a face, then you can use "flat model project" to project the other faces on the sketch plane explaining them, finally when using the cut command just choose the option "through fold".
you can get a sheet from a solid emptied, just create the part and then convert it into sheet metal. in order to have the flat model will have to be "compatible" geometrically with such operation, that is, it must have a form obtainable for bending and not with molding. If necessary, to "open" the form you can use the separation command.

 

[Ilario]

However, since it is inventor 2010, there are also the commands "explain" and "refill", where in the middle of which you can create jobs that I don't even recognize when I gave you the previous answer. . .

Yes, it is.

that do not solve the initial problem, i.e. make a round hole on a curved sheet and have the faces of the hole perpendicular to the surface of the sheet; all with one operation. This at least seems to me to be what he meant hypothesized.

 

[Ilario]

How not... It does...

 

[Tarkus]

How not... It does...

no, drilled on development as you did, give an "elliptical" hole, and you will see...:smile:
I try to reinterpret hypotheses:
I want to make a hole or better a "passage" circular on a curved sheet or a dip pipe, but I also want the walls of the hole not parallel to the axis of the drilling, but perpendicular to the surface of the sheet metal... .
As much as I tried, something like that I managed to do it only by suprivoluzione and then thickening.
ipotemusa and plotter 83 say that in swk or solidedge there is a possibility to do so with a special command in sheet metal....:smile:
I attach an example

 

[Ilario]

I understand. Now he's seeing what the solution he actually wanted.

thank you pagnotz now I try and then I know how to say:

 

[PLOTTER83]

Here I am again. I came to the design of a sheet-made carter. Starting from the solid emptied, would you be able to get the sheet metal casing folded? I with the commands available in inventor 2010 did not succeed: would it be necessary to "lace" the internal edges of the solid before converting it into sheet metal? I attach a file inventor 2010. thanks in advance. Andrea

Of course you do, of course you have to "cut" the edges that must be removed from each other, you must also give the right rays to the edges that will be explained: alcohol:
and if you want to start from a solid, I give you a advice (usual):as long as emptying the solid, immediately remove the face you do not need, you find yourself with an object composed of only surfaces that you can thicken you want, then the above things apply: opening the corners and radiating the edges.
After all this manphrine, however, it is obligatory to say that it is not the right approach to making a sheet metal object, there is the appropriate environment with the appropriate commands, which allow you to do stuff much more complex than you posted!
It's just about following some tutorials and doing some experience... :biggrin:
