Which operating records should a US OEM examine during a CNC supplier review?
Review linked records that show how one controlled part moves through the supplier's process. A list of procedures is less useful than consistent evidence connecting the drawing, material, production checks and final release.
| Record to sample in a US OEM audit | Trace the evidence through one permitted example |
|---|---|
| Order and drawing review | Show how the customer revision became the released production requirement. |
| Material and production record | Connect the incoming material identity to the job and its process checks. |
| Inspection and disposition | Relate feature results to acceptance limits and the person releasing the lot. |
| Corrective-action record | Follow an issue from containment through corrective action and verification of closure. |
Choose an anonymized or otherwise permitted example and record any missing link. An audit finding needs an owner and agreed closure evidence; viewing a procedure title alone does not demonstrate how that procedure operated.
Order and revision review
Check that the quoted and released revision matches the current customer requirement.
Production controls
Ask how setup approval, tool changes and required process checks are recorded.
Inspection record
Review a permitted example showing feature identification, results and acceptance limits.
Issue resolution
Examine how a discrepancy is escalated and how corrective actions are verified.
Can a remote review be enough for approval?
That depends on the buyer's risk assessment and approval requirements. Agree what evidence can be reviewed remotely and whether a trial, site review or additional verification is required before release.
Request a project-specific review
Send the controlled drawing, material, quantity and required evidence through the contact TDB Hanoi page. Confirm the agreed scope in the quotation before releasing work.
