Incoming & setup
Check material identity, stock condition and the released drawing before production starts.

Inspection planning
Agree the features, stages and approval points before manufacturing.
Connect the bore, slots and end features with the agreed inspection stage and method.
PROCESS · PARTS · PROJECT DETAILS
Plan inspection around manufacturing risk
Inspection stages should follow where a feature is created, where it can change and when it is still accessible.
First-piece & in-process
Review the first piece before repeating the operation. Recheck critical features after operations that may affect them.
Final & packing
Complete the agreed final checks after finishing, then match the records, quantity and protective packaging.
Project reference
| Illustrative inspection plan | First piece: selected critical features; batch: agreed sampling; final: appearance and identification. |
|---|---|
| Sampling scope | Inspection frequency is agreed per order and risk; full dimensional inspection must be specified separately. |
ENGINEERING GUIDE
Agree the inspection plan before production
Start with the drawing feature, then define the method and the point at which it is checked.
FEATURE REVIEW
Plan inspection around the mounting features
For this supplied sample, the bore, faces and hole locations provide a practical way to discuss which features need measurement and at what stage.
- Bore and mating relationship
- Face and datum references
- Hole locations and inspection stage
| Inspection stage | Focus | What to agree |
|---|---|---|
| Incoming / preparation | Material identity, drawing revision and inspection inputs. | Material documents, stock condition and applicable specifications. |
| First-piece inspection | Key features before the following quantity is released. | Feature list, measurement condition and approval responsibilities. |
| In-process inspection | Dimensions or interfaces that may be affected by later operations. | Check frequency, inspection access and record requirements. |
| Final-condition inspection | Dimensions, threads, surface condition and identification after the specified route. | Post-finish dimensions, cosmetic references and release criteria. |

Make the owner, information and decision clear at each stage.
| Stage | Inputs for review | Decision to agree |
|---|---|---|
| Before production | Approved drawing/model revision, material and critical-feature list. | Inspection scope, measurement condition and required records. |
| First-piece approval | Agreed feature checks and any open drawing questions. | Whether the following quantity can proceed and who confirms it. |
| After specified finishing | Final fits, masking requirements and accepted appearance reference. | Features requiring recheck in the finished condition. |
| Before dispatch | Accepted quantity, part identification and agreed quality records. | Release scope, packing protection and delivery split. |
ENGINEERING GUIDE
When a requirement needs clarification
A changed drawing or a questionable result needs an agreed disposition.
- 01
Identify and separate
Identify the part, revision, batch and affected feature so it is not confused with accepted work.
- 02
Review against the requirement
Review the drawing, measurement references and inspection condition before deciding the next action.
- 03
Confirm the disposition
Any proposed rework, acceptance change or drawing revision needs agreement and corresponding record updates.
Planning questions
The plan follows the actual order requirements.
Are all features checked on every part?
Inspection frequency is agreed per feature and order. Identify full-inspection requirements separately from sampling.
When should inspection records be specified?
State the format, feature numbering and approval requirements before production so the records can be planned with the route.
Does a changed drawing change the inspection plan?
Review the changed features, datums, methods and affected batches before releasing the new revision.
