laser cut intersecting tube

I've got to laser the tubes that intersect. the cut must be perpendicular to the circumference, exactly as the laser does. How do you do that?

I hope I've been clear.
 
I suppose you mean how to do it with inventor... create a tangent plane to the cylindrical surface, do a sketch on the created plane and perform a cutting extrusion. . .
 
Yes, with inventor.
I mean something else. doing as you say the "cut surface" is not perpendicular to the circumference in every point, which is what I need. while cutting the tube the laser is always radial compared to the tube.
 
in pro/e just convert the tube into sheet mode and the game is done.
I think the concept is the same in inventor.
the cuts in sheet mode, wanting, are always perpendicular to the internal surface, external or to both.

Do the tube like this:
-Revolution of surface (suppression)
-cut surface with the inclination or profile you want
- thick thickening desired.
so you get perpendicular

the suggested medote from tarkus can work.
you can also use the edge of the surface as a trajectory for a sweep (swwp of a normal segment at any point at the sweep curve).

ps: because you continue to complicate your existence by saying "..perpendicular to the circle, to the surface etc..." is said "normal" to the surface and it is impossible every mis-understanding. :biggrin:

Allow me: perpendicular and normal are synonyms

but if you want to make a tubular taken, for example, from the contained center?

so it works only in certain cases, in the subsquadri you will find interference. there are two methodologies at geometric level, then you have to apply them to inventor.

the first is to use sheet metal controls, the second with surfaces. with the surfaces you should do the inside, cut it as suggested by tarkus, make a surface offset equal to the thickness, cut the second surface and at this point thicker to create the solid. if the tube is not perpendicular to the tube on which it is grafted you have to force to use one of these systems.
I hit my head a lot with swx, but the geometry is the same for all cads!

Bye.

Of course there are some interference in the substations.
There are also in reality cutting with laser-tubes.
and these interferences obviously increase when the thickness increases.
I do not know any parametric cad that has the function of calculating the thickness interferences in the interconnection of profiles.
These functions are found in other typical programs of sheet and lattonery development.
logitrace to say one... but no parameterization, nothing; only the naked and raw development!

both with proes and with solidworks when converting into sheet metal the interferences are eliminated and in the development the cut is formed by two sweeps in which the junction points are clearly visible. These joint points coincide exactly with the point where the support passes from external thickness to internal thickness.
you can get the same profile without the sheet function by performing the procedure that I explained to you with the surfaces (even in this case both with proe and with solidworks).
If you profile so you will have no interference after cutting laser tubes. I do not know if it is possible and how to apply these procedures on inventor.
 
place an image. it can be noted that the cutting surfaces are 2 edges that delimit them are the exact point where the support on the other tube passes from inside to outside.
In this case I modeled a ø127 tube that is 45° on a tube of the same diameter.

excuse me if I do not solve the probl.data that I do not use inventor, but I can say that in swx it is possible to make any carving on the round tube through the command "wrap".it builds a tangent plane to the face of the cylinder, you draw the sketch of the desired shape and with coils you can, alternatively, channel-bearing or tracing. is a elementary operation and it would take a few clicks environment.
Greetings.

Can you post an image where you see the two tubes at the junction point?

a man of little faith... have a few sections. 45° trunks are modeled separately: one with the sheet function and one with the surface method.

I don't know. Perhaps the project curve in the 3d sketch could be useful. the third option projects the curve as envelope on cylindrical face.

for charity, but what little faith, I would only want to see the construction, but if I don't ask too much and you can post the solidworks files. . .
anyway honor and glory to solidworks

Of course I was joking. :biggrin:

What do you want to see? do you place the natives or iges/step?
