UG-77 PART MARKING
I have a couple of questions:
Is there a difference between part identification and traceability? I am trying to get my company in compliance with the code on this matter. As of now, the receiving inspector marks on the material the heat
number and schedule with a marker, the machinist records the heat number in the job packet when he receives it for production. How can attach a permanent marker on the part at each stage of machining until final assembly. Will using the heat number for traceability satisfy the original part marking identification? We are prepping for a review for our certification, as of yet we have not contacted an AI for help. Please help me come up with a way so we are in compliance.

Both are used for recalling defective parts and in both cases, parts are identified.
By tracability, in Aerospace, if we see that a part needs to be recalled, we are able to tell where the part is at all times: I know that 265 parts where manufactured, 35 of them have been discarted, 200 are in my inventory, and 30 are in aircraft with serial number such and such. I can then call the concerned customer directly to inform them of the issue.
With simple Identification, my only mean is to contact all of my customers, and ask them to verify if they have the part with serial number such and such, and change it.
You understand that in this case, I will not know how many have changed the parts. if 60% of the customers have contacted me back, is it because, the others have not received my message? maybe they have retired the product or they feel it is not necessary for them.
so you see tractability involves much more than just the numbering.
