Product Overview
GPT Precision manufactures CNC-milled prototypes for components such as housings, plates, brackets and structural parts. These samples may be used to review assembly geometry, dimensional feasibility and potential manufacturing adjustments.
Key Features
- Consider a machined housing containing a deep central pocket and a surrounding cover seating face.
- Removing material from the cavity may redistribute residual stresses within the workpiece.
- When fixture loads are released, the housing may change shape and affect the finished seating surface.
Manufacturing Considerations
- Where significant movement occurs, the result may indicate a need to review stock condition, machining sequence, workholding or finishing allowance.
- Any proposed adjustment should be assessed against the part's functional requirements.
- The prototype therefore supports both assembly verification and manufacturing process planning.
Contrôle de qualité & Inspection
- If the cover relies on the surrounding rim for contact, that surface should be evaluated according to the specified drawing requirement.
- For free-state acceptance, support the released component without forcing the rim flat.
- Measure the relevant surface across its functional area.
Specifications to Confirm
| Functional seating face | Mark the complete area that contacts the cover and specify the drawing flatness limit. |
|---|---|
| Inspection condition | Agree how to support the unclamped housing without forcing the seating face flat. |
| Review after measurement | If movement is significant, review the stock condition, machining sequence, workholding and finishing allowance. |
Assembly Considerations
Cover contact
Identify the rim or lands that support the cover in its final position.
Released geometry
Assess whether the housing can meet the specified seating requirement after fixture release.
