After setting a sine bar with slip gauges and placing the workpiece, which operation is performed to verify correct angle setting?
Sweep surface with dial test indicator tool
To verify the correct angle setting when a sine bar is set up with slip gauges and the workpiece is placed, the operation performed is to 'sweep the surface with a dial test indicator tool'. Let's discuss why this is correct and rule out the other options:
- When a sine bar is set with slip gauges for angle measurement, precise angle verification is crucial.
- The most reliable method to verify whether the setup is accurate involves using a dial test indicator (DTI). By sweeping the surface of the workpiece with the DTI:
- If the sine bar and the workpiece are set at the correct angle, the dial test indicator should show consistent readings as it moves across the surface.
- If there are variations in the reading, it indicates an incorrect setup or unevenness in the setup, requiring adjustments.
- Now, let's analyze why the other options are not suitable:
- Mark surface using scriber for checking: This method is not precise enough for checking angles since it does not give a quantitative measure of the angle or its deviation.
- Rotate sine bar to different position again: Simply rotating the sine bar won't help verify the angle; it would be more of an adjustment rather than a check.
- Measure angle using standard protractor scale: A protractor is not accurate for precise angle checking in this context, as sine bars are used specifically for their precision.
In conclusion, the most accurate and effective method for verifying a sine bar setup on a workpiece is to sweep the surface with a dial test indicator tool, ensuring the angle setting is correct.
