Laser cutting a profile from a tube... - NX10
Laser cutting a profile from a tube... - NX10
(OP)
Hi Guys,
I need to make a drawing to send to a laser cutting fabricator. The part is simply a tube that has a section cut from its wall. The laser is stationary (directly on axis of the tube) and the tube revolves around its axis and moves backwards and forwards along its axis.
How would I make this profile and subsequent extrusion accurately? Ordinarily I would simply make a sketch on the appropriate plane, extrude and trim but this does not accurately simulate the cutting path of the laser which stays at 90 degrees to the axis and tangential to the surface of the
tube at all times...
many thanks,
James

If you have the Fill Surface feature ( don't know what license it belongs to) Use that to create a face inside the wrapped curves. Else you can use Divide face.
Thicken the face ( Thicken feature).
then ?

I used a Law extension surface, normal to the outer face, to trim away the interior.

It's better to model it accurately but sometimes it isn't worth the hassle, IMO. Especially when the tube is thin wall, like .040" wall on a 3" diameter.
