Hello @m.legras
I figured out how to do it (it seems to me) except that I don't know if the laser beam is doing towards the center as I did.
It's quite simple if you tolerate a very slight imperfection
Look at the cross-sectional images (in the zip) and let me know what you think. If it's good, I'll make you a mini-tutorial
Kind regards
zozo_mp,
Tube thickness cutouts should be perpendicular to the thickness like a sheet metal cut. The laser beam goes towards the center of the tube. The laser head rotates around the axis of the tube to make the cuts.
Hi @ all
me my problem
with the normal cutouts to the profile
of the 2 bodies
This is the junction of the 2 bodies
I'm not convinced that it goes well
It is true that depending on the thickness we should have a clearance for a good weld that corresponds to the thickness of the said tubes

Hello @gt22
There is always the solution of a filing / finishing beveling for the case of glued or interlocking joints, but as you say, for welded parts a space is preferable.

Bravo @m.legras
That's high-flying!
Forget my solution, it does not correspond to the laser cutting in the center as you want it which in fact and always perpendicular to the tangency point.
On the other hand , is it your drawing that will be used to control the Laser tube because you have defects on the surface after laser cutting on your model?
Kind regards
Hello
I tried a little on my side, I used the "Winding" function.
Maybe my method (provided in pj) could help you.
To have a well-defined shape, you will have to fiddle with the equations but it should be possible.
Kind regards

Hi all
I hope I have understood the question well and not created redundancy with respect to the answers already given.
For my part, I suggest going through thickened surfaces:
Step 1: Create the (outer) surfaces by scanning
Step 2: Restrict the surface area of the tube that will be cut
Step 3: thicken the outer surfaces to obtain the tubes
I attach my 2019 version of my coin in PJ.

Advantage:
Thank you all for your involvement in this post
Thank you all for your involvement in this post
As AC COBRA 427 said, the laser nozzle is always perpendicular to the surface of the tube and focused on the center of the tube. Hence the complexity of the surface area generated ...
It's super interesting to discover all your solutions. The winding is awesome Gauthik!
But it must be complicated to draw the shape corresponding to the connection on a tube bend, right?
For the thickened surfaces, mgauroy, I reworked your file. You have to take the inner surface and then thicken. It also works very well. I haven't tried on a link on an elbow yet. But the solution is also interesting.
Big bug this morning on the forum for me. I see that my post has gone into solved when not necessarily! And impossible to put screenshots...
Anyone know how to uncheck the resolution of the problem?
Hello @ m legras
It's nice to thank all the people who contributed to this com thread to try to solve your problem and we thank you for it
But do you really think that this is the best answer, the one that is designated
have a nice day @+ ;-)
Sorry, big bug this morning, I had typed a novel to thank everyone and take stock of the answers and once published, there was only the first sentence and my message got through and validated as a better answer!! ... Nothing understood and in no way do I think my post is finalized. There are plenty of good answers in there and you just have to test everything. I hope it's as interesting for you as it is for me. A BIG thank you to all in any case
Hello @m.legras
"Anyone know how to uncheck the resolution of the problem? "
This is not possible, we will have to tick another "best answer" to replace it.
Kind regards.
I have a simple 2-step solution if anyone is still interested...
Hello @tarikc24 ,
Yes, I'm interested. Especially since I'm on the same subject but for rectangular tubes.
I have a solution by surfaces following the path of the beam but if you do it in 2 steps, I'm interested !!
'Simple', effective and workable solution:
1) obtain the inner or outer curve (with 'projected curve' for example or intersections of surfaces). here I did it on the inside
2) Split the surface to be cut with the "sewn surface" tool and the previous curve (the inside of the tube)
3) "Thickening material removal" from the stitched surface to be removed. For safety, make it bidirectional and take more than 2x the thickness of the part; The advantage of this function is that it removes the material normally from the surface
FINITE
See PCs modified on one side in V2020
The image of the modified part for those who do not have SW2020 (in green the intersection curve of the surfaces obtained thanks to the dividing line)
Nb: on the part obtained, the heel is heeled on the lower part. No simple solution in my opinion to avoid this geometric problem. The curve obtained in the first step should be modified to shift it slightly in order to avoid this interference.
Removing interference is not that complicated: redo the same work but on the outer surface that is interfering.
see the final PC
After checking, there are still micro interferences. If you want to be 100% interference-free, the best thing to do is probably to make a slight offset of a few tenths on the limit surface. (surface-sweep1) before removing material.
Small technical detail: As the cut is at the end of the curve, there will inevitably be deviations in real life. If you want to be sure of the geometry you would have to cut on a straight part (less beautiful on the other hand ..)
