- Inspection
- Verify related features from the specified datums
Product Overview
Custom aluminum components can include pockets, side holes, locating features, thin walls and multiple machined faces. The machining scope is reviewed against the drawing, material and inspection requirements.
These parts may require more than one machining orientation, making tool access and datum control important considerations.
Key Features
- Consider a housing where a pin passes through a side bore to engage a component located inside a deep pocket.
- The side bore and internal locating feature must align according to the assembly requirements.
- Machining the features to their individual size tolerances may not be sufficient if their positional relationship is incorrect.
Manufacturing Considerations
- Where practical, machining related features in one setup can reduce relocation requirements.
- When the part must be reoriented, the fixture should establish the necessary relationship to the approved drawing datums.
- Thin walls may require additional support to reduce movement during cutting.
- Clamping loads should be applied to suitable regions without distorting critical features.
Quality Control & Inspection
- After machining and fixture release, evaluate the bore and internal locator using the specified datum reference system.
- The measurement approach should be capable of accessing the critical features in the required acceptance condition.
Specifications to Confirm
| Cross-face relationship | Specify the side bore and internal locator relative to the approved drawing datums. |
|---|---|
| Wall and setup | Identify thin walls, clamp-safe areas and restricted tool access. |
| Acceptance condition | Confirm fixture release and the required measurement access. |
Assembly Considerations
Pin engagement
Show where the pin must engage the part seated in the pocket.
