Re: laser cut tube

Legend

We have been using this technique for a while now and it has yielded great results. For example, we had an assembly that was made from 5 tubes and one 4 mm thick metal plate, so a grand total of 6 different parts.

 

Now we make that same assembly with one long tube that has been laser cut and can be bent to the final shape, saving a LOT of work time. The seams are so neat and tight after bending, that we only have to weld the inside of every bend (compared to all four sides before).

 

EDIT: pictures below are after hot-dip galvanizing

We have outsourced the design process to the laser cutter. We send the completed assembly in an IGS-file and they design all the cuts and other stuff with a specified CAD program intended for such use. There are quite a lot of things you have to consider designing those cuts (lightening cuts on sharp angles so that the tube won't bulge outwards, microbridges that can be smashed open when bending the tube etc.), so we saw it more efficient to let those who are specialized in that do the designing.

 

And as @Craig_H mentioned, cuts have to be normal cuts when using 4-axis laser head, so take that into account especially when designing with round tubes.

Hopefully SE create the option in part environment to create a cutout "normal to surface" just like in sheetmetal. It was definitely high on the list of wanted features from users at this past SEU, hopefully in the works.

Hi @Craig_H

 

 

without fully understanding what was going on in that thread I want to say, that a normal cutout is available in part environement for a long time.

 

You only have to create a curve on those surfaces first to use it.

Yes, but to make a simple tube notch it requires many steps. Normal cutout works great for the initial cut, but for subsequent cuts at the same tube end you're left with curves that are interrupted, you need to then draw a line to close them. basically it takes 20 steps to maybe 5 that it takes in sheetmetal enviroment. 

What some of us were asking for is to use the cutout command but it would automatically create surfaces normal.

just a thought here....   anyone try the new solid sweep for this sort of feature.  create a solid cylinder representing the kerf...  then sweep it along the true laser path...  this should give you exactly what you want... ???

Hi @Johnson_BigMatt

 

 

this could work!

 In any case will it be worth to try

Hi @Johnson_BigMatt

 

 

OK so far the first attempts didn't finish successfully

 

Maybe there is some trick or option I don't see at the moment, but ....

Problem (for me at least) is the laser path is created from multiple notches where one tube intersect 2-3+ other tubes. Getting that path as one continous line is not as easy as it could be.
