Formed Tab Height in the Specified Condition
Precision Metal Stamped Components
Precision stamped components with small formed features requiring controlled support and clearly defined inspection conditions.
- Process
- Review the formed tab and the clearance it controls
- Материалы
- Confirm sheet grade, condition and thickness
- Количество
- State trial and expected production quantities
- Inspection
- Measure from the specified datum in the stated condition
Product Overview
Custom metal stamped parts may contain small tabs, spring-like details, locating flanges and other features that are sensitive to handling or measurement forces.
A nominal dimension alone may not fully define the required inspection condition.
Key Features
- Consider a small formed tab that must provide clearance to an adjacent assembly surface.
- If the tab is flexible, fixture pressure or contact from a measurement probe may change its apparent height.
- The reading can therefore depend on how the part is supported and whether an external force is applied.
Manufacturing Considerations
- For a free-state requirement, support the component as specified without forcing the tab into position.
- For a restrained or loaded condition, reproduce the approved support arrangement and any specified load location, magnitude and direction.
- The inspection method should be appropriate for the tab geometry and specified tolerance.
Quality Control & Inspection
- Determine the tab height relative to the designated datum plane and the point or surface identified on the drawing.
- Compare the result with the requirement applicable to that measurement condition.
- Where functionality depends on the formed feature, an agreed assembly check may complement dimensional inspection.
Specifications to Confirm
| Height reference | Identify the datum plane and the point or surface on the tab to measure. |
|---|---|
| Measurement condition | Specify free-state support or the prescribed restraint and load, as applicable. |
| Acceptance limit | Provide the tab-height tolerance and the drawing revision. |
Assembly Considerations
Seating and clearance
Show the seating face and the mating surface that the tab must clear.
Measurement setup
Choose support and a measurement method that preserve the specified tab condition.
