Machine Design #86: Standard Material Names — One Material Should Not Have Five Names
MINATA turns the Vietnamese source into an evidence-led guide. standard material name must remain clear, manufacturable, searchable, inspectable, and maintainable when the boundary changes.
Function before naming
Write the function, input, expected result, failure symptom, acceptance limit, and measurement method before selecting a name, mark, material, or note. Assign an owner to every value.
Core checks
- Grade, specification, and material condition: record value, source, method, owner, and pass/fail evidence.
- Local and supplier naming equivalence: record value, source, method, owner, and pass/fail evidence.
- Substitution rule and approval: record value, source, method, owner, and pass/fail evidence.
- Drawing, BOM, purchasing, and certificate match: record value, source, method, owner, and pass/fail evidence.
- Heat treatment or surface condition: record value, source, method, owner, and pass/fail evidence.
- Traceability and audit evidence: record value, source, method, owner, and pass/fail evidence.
| Failure mode | Symptom | Verification |
|---|
| Ambiguous identity | Wrong part or record | Search and audit a real lot |
| Omitted interface | Purchase, assembly, or service error | Walk the real route |
| Documents out of sync | Correct name, wrong revision | Baseline every reference |

MINATA release checklist
- [ ] Function, identity, boundary, and failure symptom are written.
- [ ] Ownership, interface, and mistake-proofing are clear.
- [ ] Six topic checks have evidence and pass/fail limits.
- [ ] Manufacturing, purchasing, inspection, and maintenance were tried.
- [ ] Revision, supplier, database, and lifecycle records agree.
Good engineering is an explicit chain that survives manufacture, operation, maintenance, and change. For standard material name, evidence that identification and function remain reliable is the MINATA standard.
