Making blanks into multiple part numbers still referencing original in BOM
Making blanks into multiple part numbers still referencing original in BOM
(OP)
We have sheet metal parts and want to have multiple parts all made from the same blank part number. How can we do this and still reference the correct blank in the BOM?
We also use rivets that rivet together multiple thicknesses of sheet metal parts but only use one rivet part number. How do I model those to accommodate for each different thickness? Also if we use a rivet model to make the actual print for to order that rivet, how do we have one in the raw form and one with a bucktail?
Thanks Guys!!!

Don't forget to specify what version of NX you are on.
RE: Making blanks into multiple part numbers still referencing original in BOM
Lets use the sheet metal as an example. In real life the blank has one part number. We then take that blank and it gets a varying angle of twist, radius, and different pattern of holes for each finished part number. We are also using TeamCenter 8 and eventually we want it to reference the different stages all the way back to the material coil it is stamped out on.
So my first thought is just take the blank and pull it in as an assembly in the finished part number. But then you can't modify it in the way we want.
So maybe "deform" might work? (Not sure how to use it correctly and efficiently. I've heard bad things about deform if not used properly.)
Thanks!
RE: Making blanks into multiple part numbers still referencing original in BOM
If you are using an existing part as a starting point to create a new part, you should look into both promotions (promote body) and wave linked bodies (wave linking). Both of these commands will allow you to copy geometry out of a part file into a new part file and then make modifications to it. Both commands will maintain links back to the original file. Search the help files and this forum for more information, tips, and tricks.
For the different forms of the rivet, you could model both shapes in the rivet part file then use reference sets to determine which is used in the assembly. Since you are running TC, you can also use "altreps" (alternate representations), which is essentially a higher powered version of the reference set method (probably overkill if you are only dealing with 2 forms of a single part).

Like Cowski said, you will bring the blank into the part that will be your finished part using Assemblies, and either use Promotions or Wave Linking followed by what sheet metal commands it takes change the model into what you need.
What you may want to do as far as referencing the Coil is have a NX model file with nothing in it but the proper attributes for the coil, and bring that into the file that contains the flat blank. It will then appear in the tree that you are creating, but nothing will physically be there.
I haven't used NX7.5 Sheet Metal yet so I am not certain what to tell you about the name of the commands that would be used to bend the metal blank. But I will look into it if I can find the time today.

What you may want to do as far as referencing the Coil is have a NX model file with nothing in it but the proper attributes for the coil, and bring that into the file (using Assemblies) that contains the flat blank (or whatever comes after the coil). It will then appear in the tree that you are creating, but nothing will physically be there.
RE: Making blanks into multiple part numbers still referencing original in BOM
I tried bringing in the part using promote and wave. Both do not pull in the expressions nor the history. So the blank is not (easily) up-datable in the assembly...
The way the blank was made was to to model it twisted and then return it its flat form (not taking the blank form and twisting it...) Do I need to rethink this?
Does any of that make since?
Sorry to be a pain and thanks for the incite!
