Geometry Problem Cut Pipe Laser

[mario170979]

Hello, maybe somebody can help because i dont get a idea who to archive this. Attached a pictures. problem is that for a T-Welding Connection we should prepare CAD Files for a Laser Cutter. which can only cut vertical to the surface (90°) different cut out dont work well. so my best guess actual is attached but the transition is still ****. So simple extrusion in inventor helps not. any idea?

what version are you running?

[blandb]

scratch that, I see it lol...sorry

Cut it like the laser.

Assuming your laser rotate the pipe when cutting.

Use pipe ID profile after cope.

Delete all surface leaving only ID.

Thicken ID with pipe thickness.

Use OD profile for laser.

Is this what you're looking for?

Are you using Frame Generator? I don't remember if 2020 had the option yet of doing a Perpendicular cut when notching members, You could see if that helps. Or if not using FG, what about the method I show in the attached video?

@blandb - that's one of the cleanest processes I've seen for that type of cut and was about to rethink all the tube-laser work I've been doing... but there's a problem:

This cut isn't perpendicular to the face - so the transition from correct to incorrect happens somewhere round the back of the joint.  I'll investigate your process though - it looks much easier than mine.

I've attached my current process (for the odd occasion I don't use Frame Generator).

Hi Peter,

This can be fixed up relatively easily. Use Thicken command -> uncheck "Auto-Blending" -> select the inner face of the tube -> Intersect -> distance = thickness. The same approach also applies to sheet metal parts with non-perpendicular side faces.

Many thanks!

I see I uploaded the wrong one.....See this one...There is a second split to clean it up...All this is just a mock of what happens when you utilized the perpendicular cut from Frame Generator. But it works great if you are one that doesn't use it. I worked for a couple different companies who hated it and we were not "Allowed" to use it.

Please see attached:

I tried this and could not get it to work until I chose the "OUTER" face, is that what you meant? 2023 version attached.

@pcrawley 

I have done the surface way as well too, it is smooth. But I was going this route just incase a user didnt want to necessarily start over, but maybe able to salvage what what there?

Your updated version works for me.  That last Thicken feature is clever.  Thanks @blandb & @johnsonshiue - I'd mark this as the solution if it was my post 🙂

Regarding Frame Generator: "I worked for a couple different companies who hated it and we were not "Allowed" to use it."  I'm pleased that is in the past for you.  I can't imagine the mentality of having such awesome tools and preventing their use.
