- 3. ________________ micrometer is a type of internal micrometer with a single spindle end that separates from a fixed end as an operator turns the spindle screw.
- 5. ______________ micrometer measures the outside diameter of a part at grooves, gaps, and other features along the part
- 8. __________ gage is a U-shaped gage with hardened, adjustable anvils on opposite ends used to inspect the length of part features.
- 10. The degree to which an instrument will repeat the same measurement over a period of time.
- 13. To compare and adjust a device with unknown accuracy to a device with a known, accurate standard
- 14. _______________ scale is a smaller cale sued alongside a larger graduated main scale that divides the smallest units of the main scale into even smaller units.
- 17. _____________ micrometer has an anvil that reaches into holes and other internal part features to measure depth
- 18. _______________ micrometer is a type of internal micrometer with an anvil on the handle end and a spindle end that increases or decreases the length of the micrometer as it extends and retracts.
- 20. Machinist's _______________, also known as a steel rule, is a simple measuring instrument consisting of a long, thin metal strip with a graduated rule.
- 21. __________ gage is a hardened, cylindrical gage used to inspect the size of a hole.
- 23. A fixed jaw against which an object to be measured is placed
Down
- 1. A ring or cylinder that fits around the spindle of a micrometer and contains a smaller scale than the main scale.
- 2. An unwanted but acceptable variation or deviation from a desired dimension of a part.
- 4. _____________ rule is also call machinist's rule
- 6. Also known as resolution, it is the smallest unit of measurement that an instrument is capable of displaying
- 7. ____-_____ gage is a gage purposely designed to not fit with correctly sized parts.
- 9. The difference between a measurement reading and the true value of the measured dimension
- 11. ________________ device is a device with a known measurement used to determine if a variable inspection device is providing accurate measurements.
- 12. ______________ gage is a measuring device with a column mounted on a base such as a granite surface plate, and a unit with an extending arm that slides up and down along a main scale beam.
- 15. ______________ micrometer is also called an inside micrometer.
- 16. The smallest unit of measurement that an instrument is capable of displaying and is also known as discrimination.
- 19. __________ Anvil Micrometer can more easily measure parts with curved surfaces
- 22. An instrument with an established standard size that is used to determine whether a part feature passes or fails inspection. It does not determine the degree of variation.
