  1. Reading the Micrometer By Mark Zidon University of Wisconsin-Platteville

  2. Objectives • Identify micrometer parts • Determine micrometer reading

  3. sleeve thimble anvil spindle frame This is a English micrometer

  4. 3 0 1 2 3 4 5 6 7 8 9 2 1 0 24 22 For clarity we will use an animated figure. 23

  5. Let’s take a close look at the sleeve of the micrometer.

  6. One inch (1.000) 25/1000 inch (0.025) 3 0 1 2 3 4 5 6 7 8 9 0 0 1 2 3 4 5 6 7 8 9 0 2 1 0 24 23 22 1/1000 inch (0.001) 1/10 inch (0.100)

  7. Now, an example...

  8. Smallest Measurement Largest sleeve reading 0 1 2 3 4 5 6 7 8 9 15 18 0 1 2 3 17 0.341 inches One mark past largest sleeve reading 16 15 14 13 Thimble Reading Now, an example... 19 18 17 16 0.000 15 14 13 0.300 0.025 0.016

  9. A digital micrometer

  10. Another example...

  11. Smallest Measurement Largest sleeve reading 0 0 1 2 3 4 24 23 22 21 3.496 inches 20 19 18 17 16 Thimble Reading Three marks past largest sleeve reading Another example... 20 15 3.000 0.400 0.075 0.021

  12. Review... • Lightly tighten on object. • Determine smallest measurement when micrometer is closed. • Find largest visible number on sleeve and multiply times 0.100.

  13. Review... • Count number of marks past largest visible number on sleeve and multiply times 0.025. • Multiply thimble reading times 0.001. • Add all numbers to get answer.
