Using a Ring Gage to Inspect Internal Diameter
Using a ring gage to inspect a component’s internal diameter involves a series of steps to ensure accuracy and consistency.
- Prepare the component and the ring gage: Ensure both the component and the ring gage are clean and free from debris. This will prevent inaccurate measurements and potential damage to the tools.
- Insert the ring gage: Carefully insert the ring gage into the component’s bore. The gage should slide in smoothly without excessive force. If the gage encounters resistance, it may indicate that the component’s diameter is outside the specified tolerance.
- Check for a snug fit: Once the gage is fully inserted, check for a snug fit. The gage should not move freely or fall out of the bore, but it should also not be overly tight. A snug fit indicates that the component’s diameter falls within the acceptable tolerance range.
- Measure the ring gage: If the gage is a “go” gage, the component passes the inspection. If the gage is a “no go” gage, the component fails the inspection.
- Remove the ring gage: Carefully remove the ring gage from the component. Avoid using excessive force or twisting the gage, as this can damage the component or the gage.
Inserting and Removing the Ring Gage
Proper insertion and removal techniques are crucial to avoid damaging the ring gage or the component.
- Insertion: When inserting the ring gage, apply gentle pressure and ensure it enters the bore smoothly. Avoid forcing the gage, as this can distort the component or damage the gage.
- Removal: When removing the ring gage, pull it straight out of the bore, avoiding any twisting or side-to-side movement. Excessive force can damage the gage or the component.
Determining Pass/Fail Criteria
The criteria for determining whether a component passes or fails the inspection are based on the ring gage’s measurements.
- Go Gage: A “go” gage is designed to fit within the maximum allowable diameter of the component. If the “go” gage fits snugly into the bore, the component passes the inspection.
- No Go Gage: A “no go” gage is designed to fit within the minimum allowable diameter of the component. If the “no go” gage does not fit into the bore, the component passes the inspection. If the “no go” gage fits into the bore, the component fails the inspection.
