Revision Control & Coated Bore Acceptance
Coated Locating Bore Verification for Production Release
Moving from an approved prototype to repeat production while controlling drawing revisions, critical features and verification requirements.
- Process
- Verify the locating bore after finishing
- 材料
- Material and coating per the approved revision
- 数量
- Prototype and production sample quantities per plan
- 检验
- Finished bore and fit against the approved criteria
Product Overview
An approved prototype demonstrates that a particular sample has met the agreed evaluation requirements. It does not automatically establish that every later material, geometry or finishing change is acceptable. Before repeat production, the applicable drawing revision and critical requirements should be confirmed.
Key Features
- Consider a locating bore whose final fit is affected by a coating change.
- The coating may alter the finished bore size and available assembly clearance.
- A sample manufactured using the intended production route can be evaluated after finishing against the revised approved requirements.
- The result helps determine whether the proposed change meets the specified acceptance criteria.
Manufacturing Considerations
- Changes affecting functional features, material condition, coating thickness or mating geometry may require additional review.
- The change record should identify the affected requirement, approved decision and any inspection or trial work needed.
- Temporary deviations should have a defined scope and applicable end condition.
Quality Control & 检验
- The production order should reference the correct approved drawing and related specifications.
- Any agreed inspection or first-article requirements should be included before production release.
- Where exceptions apply to particular lots, their scope and authorization should be documented.
Specifications to Confirm
| Approved baseline | Identify the issued drawing revision and the coating requirements that govern the fit. |
|---|---|
| Production sample | Use the intended production route and measure the bore after finishing. |
| Release evidence | Record the result and the scope and authorization of any lot-specific exception. |
Assembly Considerations
Finished bore fit
Verify the finished bore against the mating feature and the required clearance or interference.
Release boundary
Apply the verification to the issued revision and the authorized scope of the release.
Discuss Prototype-to-Production Requirements
Send the approved prototype revision, updated drawing, required quantities and details of proposed changes. We can review their impact on manufacturing and inspection scope.
