Tue Jul 05, 2011 7:36 pm Threads into sheet metal? |
 |
|
|
I'm trying to figure out what would be the best way to install threads into sheet aluminum (1.587 mm), it seems to me at though it would be some variety of threaded insert, but I can't seem to find any for metal this thin.

So I just need to specify which size needs to go in each hole or do I need to link to the very type as with regular fasteners?
Also, it is possible to specify a hole to be countersunk without having it assume I want it CNC machined and to just use a countersink bit?
And a third question, the analyzer says that my bends might be impracticable, and getting this design to where its ready to order would take a while, can I just post it on the forum to have it checked out? It isn't finished but I already have the possibly problematic bends done.

You should link to the exact item.

I'm having a hard time how to pick a nut, I'm looking to put strong threads into a 1.587 sheet of 5052 aluminum, what should I look for? Will this work?
How do I go about specifying a countersink? Just leave a comment? I can't just specify a Chamfer because I have more than on part.
The bends in question are for an enclosure, it isn't done yet, but the most complex bends are there.

All pem nuts have strong threads. We prefer that you select from mcmaster.com.
Yes, add a comment for countersinks in 2D parts.

What I meant was that I was having a hard time figuring out what sort of nut I need for this application. Should I use a broach style or clinch style nut? McMaster specifies broach style for soft metals, but clinch style for sheet metal, and aluminum sheet metal fits both those descriptions unless they're using sheet metal as a term for steel sheet metal.
And is there any update on if my bends will work or not?

Mcmaster is using "sheet metal" to imply steel. Your bends are OK.

I'm confused as to precisely what "flatness" pertains to and why the lowest value that the program will let me select is 7.6mm.

Please post your file. Flatness is covered in Auto Specs.

I read that page but I'm still not 100% on what it means. Shouldn't the flatness be dependent on the sheet metal used?

Does this help? The type of metal might effect flatness but that is not your problem. Your responsibility is to set a spec. eMachineShop's is to meet the spec.

I understand that, but the analyzer won't accept a value under 7.6mm, if I set it lower than that it says that that configuration isn't available and it tells me that 7.6 mm is available and that seems to be the flattest flatness it will let me select.
And would flatness apply to how straight and even the cuts are or how flat the material is before being cut?
