MANUFACTURING / JAPAN SOURCING
Metalworking from Japan: define the finished part and process scope
A drawing can lead to several offers with different supplied states. Separate material supply, fabrication, finishing and inspection before comparing a custom part quote.
Define the delivered item and the included work
Start with the finished item and its interfaces, then identify which operations you want quoted. FARO’s fabrication and welding examples distinguish checks at earlier assembly stages.[1] Such checks do not automatically replace the acceptance required for your finished part.
Include drawing/data revision, quantity or capacity definition, destination and required timing. Mark fixed requirements, requested proposals and decisions still open.
- 1Item: part or machine and its supplied state
- 2Work: operations, interfaces and responsibilities
- 3Acceptance: inspection, trial and delivery records
Enquiry scopes, not a universal process sequence or confirmed supplier capability.
Choose the product or process family
The rows are starting questions. Each process or machine application needs its own source work, technical review and acceptance definition.
| Product family | Describe first | Clarify the scope |
|---|---|---|
| Machined parts | Describe firstMaterial, drawing, datums and finished state | Clarify the scopeMachining, deburring, finish and measurement |
| Sheet-metal enclosures | Describe firstMaterial/thickness, bends, interfaces and assembly | Clarify the scopeForming, joining, finish and fit checks |
| Stamped parts | Describe firstDrawing, production material, volume and tooling stage | Clarify the scopePrototype versus production tool/part approval |
| Forged or cast parts with machining | Describe firstBlank, material state and finished drawing | Clarify the scopeBlank supply, machining allowance and inspection |
| Fasteners, springs and fittings | Describe firstExact type, geometry, duty and connection | Clarify the scopeProduct-specific performance, finish and tests |
| Welded structures | Describe firstDrawing, joints, process stage and measurement state | Clarify the scopeFabrication, machining and dimensional/weld acceptance |
| Surface treatment | Describe firstSubstrate, process, functional surfaces and masking | Clarify the scopeCoating scope, measurement state and acceptance |
Begin with a specific acceptance decision
The following guide makes the conditions behind an apparently simple result visible.

Original diagram, comparison table and supplier questions.
Retain the requirement, the offer and the accepted configuration
Keep material/workpiece, drawing, process and configuration references identifiable. Record proposed deviations, evidence still required and who can approve the result.
Define packing, handover, remaining site work and changes requiring review. Check actual supplier capability and product origin for the offer; a sourcing enquiry does not establish either by itself.
