Part number Scheme
Part number Scheme
(OP)
Have a meeting in 2hrs to discuss part numbering and models. Which numbering method / solidworks model configuration would you like better:
WST-1000 (MAIN WELDSTUD PART NUMBER AND MODEL)
WST-1000-1 1/4-20 X .50"
WST-1000-2 1/4-20 X .75"
WST-1000-3 10-32 X .50"
WST-1000-4 10-32 X 1.0"
(OF COURSE ALL THE SIZES OF THREADS ARE GROUPED TOGETHER AND THESE ARE ALL CONFIGURATIONS DESIGN TABLE DRIVEN FROM THE WST-1000 MODEL)
OR
WST0001 =1/4-20 WELDSTUDS
WST0002 =10-32 WELDSTUDS
WST0003 =8-32 WELDSTUDS
THEN YOU WOULD HAVE A CONFIGURATION UNDER EACH OF THE ABOVE MODELS:
WST0001-A =1/4-20 X .50
WST0001-B = 1/4-20 X .75"
ECT....FOR EACH "WST" P/N.
Which example works best?

RE: Part number Scheme
If only those two choices, I'd pick a modified #2. Not sure why you changed the configurations to use letters when numbers work just as well. Using letters, you are limiting yourself to only 26 configurations unless you go to double or tripple letters. If you do that, numbers would be better.

RE: Part number Scheme
Plenty of schemes already exist along the lines of
WSTDDLL
Where DD is the diameter and LL is the length. Typically for inch sizes DD and LL are the number of 16ths.
So a 1/4 diameter 1.25 long stud would be
WST0420
RE: Part number Scheme
I'd avoid special characters and spaces etc. Not sure if you have a PDM system but some systems and even some file structures etc. don't like spaces or special characters.

RE: Part number Scheme
I recommend not using dashes in your part numbers. When MRP/ERP people enter numbers, they systematically delete dashes and other non-significant symbols. You want everyone on the same page.
One problem with signficant part numbers is that, sooner or later, they are entered by untrained people in a blind, screaming panic. Once parts are incorrectly classified and entered into your MRP/ERP system, you cannot change them, and your significant system is broken.
Your part classification should be a field in your MRP/ERP database. Mistakes can be corrected. Changing circumstances can be coped with.
I am a firm believer in never changing part numbers. I have seen it done many times, and it always causes confusion. Do not come up with a process that forces you to do this.
RE: Part number Scheme
The major reason is that there is always going to be some extra spec that makes this or that screw just different enough where it will require it's own part numbers. For example, what if material of the fastener becomes important. How would you handle two same screws of different materials? Then there's head type (pan head, flat head 82deg, flat head 90deg, flat head 100deg, cheese head, round head, button head, socket head cap screw, flat socket head cap screw, fastening type (philips/slot), locking, attached star washer, attached interior toothed washer, attached plan washer, finish, etc. You really going to come up with a number scheme that is going to support ever option from the start? Smart systems are rarely expandable to the degree necessary to support the possibilities that are eventually employeed.
