Square tubing corner laser cut
EricGauthier
Member Posts: 73 ✭✭✭
Hi everyone,
Here is an image of a rectangular HSS tubing.
I want to laser cut this tubing at angle.
Laser cutting kerf is always perpendicular to outer face of the tubing.
Face A is perpendicular to face B and face C is perpendicular to face D. This is the easy part to model.
Now the more difficult part:
How can I make the transition (remove material) between point E and point F and make it perpendicular to (curved) face G?

If for any reason you can not use the sheet metal solution, use Thicken feature to get boundary normal to curved surface.
Since I'm modeling a rectangular tubing (closed profile), see here how I tried your solution and please tell me what I'm doing wrong.
If it works, I'll then be able to close my profile...
Can you show me your solution using Thicken feature? I don't get what you mean.

Here is what I want but on a HSS tubing, not a sheet metal.
IR for AS/NZS 1100
Your sheet metal example was getting bend reliefs. That can be avoided if you set bend relief option to Tear in the sheet metal model feature:
Here is the Thicken solution.
Try to use the "Thicken" feature!
I changed the SM setting as you wrote and now it is better.
@mbartlett21
Your solution works like we can see here. But is there a way to rid of the red warning?
And mixing your solutions, I don't know why I don't get the same result in both Parts.
@sebastian_glanzner
Can you give a link to your suggested solution?
Sure: https://cad.onshape.com/documents/e11b70e1b0a75a337eb51b1e/w/16a6bc449ba097fee8d2110a/e/c416ccf2b0d9be203ec07436
I also added a round bar cutting through the square pipe:
I don't understand why in this document when I select the last face to complete my thicken, the function turns in error.
Good question!
Maybe the Onshape Support can help?
Already created a ticket, will get back here when I have the solution.
Thank you!
Waiting for more than a week now to get an answer from Onshape support. They don't even have a look to my support ticket! )-:
I just looked at your model again and I think it could help if you remove the small face here:
Try a cut like in your very first post:
Also you can try to thicken the inner faces first.
Then thicken the outer surface with a second command.
I tried to remodel the pipe and it works:
So the solution (w/o sheet metal) is what @pete_yodis suggest: sketch + split face + thicken.
