“Work at getting organized like a hobby. Set aside a certain amount of time each day. While it may indeed take a fair amount of time to establish order, once it is achieved, you will save more time than you have ever spent.”

Measurementand Measuring Devices
(Micrometer and Vernier Caliper)
Doc. No : SKF/TR/02 Rev. No : 0 Effective Date : 20.4.11
What are we going to do today?
• 1) We are going to read and use the following instruments in measuring certain quantities:
– Micrometer– Vernier Caliper
Doc. No : SKF/TR/02 Rev. No : 0 Effective Date : 20.4.11
The Micrometer
• A micrometer allows a measurement of the size of a body. It is one of the most accurate mechanical devices in common use.

How to read and use the Micrometer?
Doc. No : SKF/TR/02 Rev. No : 0 Effective Date : 20.4.11
1) The line labeled 0 is the primary pointer. When it lines up with the central horizontal line on the cylinder, as shown, then the distance between the measuring rods is exactly an integral or half-integral number of millimeters.
2) The left-hand side of the thimble has markings all around it.
3) In this case, then, the distance between the measuring
rods is 7.000 mm. The upward line on the cylinder corresponding to 7 mm is barely visible under the thimble.

Doc. No : SKF/TR/02 Rev. No : 0 Effective Date : 20.4.11
Remember!!!
• Report to 3 decimal places. Your instrument is capable of reading up to thousandths of a millimeter. ( That is why it is called a micrometer, 10-6 of a meter).
Doc. No : SKF/TR/02 Rev. No : 0 Effective Date : 20.4.11
1) If we rotate the thimble one complete revolution so it moves to the right, it will look as shown.
2) Now the distance between the measuring rods is 7.500 mm. The downward line on the cylinder corresponding to 7.5 mm is barely visible.
3) Note that this is all consistent with the fact that the markings on the cylinder correspond to fifty divisions for a complete revolution. Thus the numbers on the thimble correspond to hundredths of a millimeter.
7
7.5
7.5+0.000 = 7.500 mm
Doc. No : SKF/TR/02 Rev. No : 0 Effective Date : 20.4.11
• One more complete revolution takes the distance to 8.000 mm, as shown.
8
0.000
8.000 mm + 0.000 mm = 8.000 mm
Doc. No : SKF/TR/02 Rev. No : 0 Effective Date : 20.4.11
• Now turn the thimble just a little bit more, and end up with the situation shown.
• We have increased the distance by 0.120 mm from 8.000, so the distance between the measuring rods is now 8.120 mm.
8
0.120 mm
8.000 mm + 0.120 mm = 8.120 mm
Doc. No : SKF/TR/02 Rev. No : 0 Effective Date : 20.4.11
• If we give the thimble one complete further rotation, we end up with the micrometer as shown above.
• Now the distance is 0.120 mm greater than 8.500 mm, so the distance is 8.620 mm.
8.5 mm
0.120 mm
8.500 mm + 0.120 mm = 8.620 mm
Doc. No : SKF/TR/02 Rev. No : 0 Effective Date : 20.4.11
• Finally, if we turn the thimble a tiny bit further, it might end up like the figure above.
• Now the distance is greater than 8.620 mm, but clearly less than 8.630 mm. We might estimate this reading to be 8.624 mm.
8.5 mm
0.120 mm
8.500 mm + 0.124 mm = 8.624 mm
Doc. No : SKF/TR/02 Rev. No : 0 Effective Date : 20.4.11
• Depending on your eyes and screen resolution, you might be fairly confident that the reading is less than, say, 8.627 mm and similarly confident that it is greater than 8.621 mm. Thus you might assign a Reading Error to this measurement of 0.003 mm
• So, we would report the distance as 8.624 ± 0.003 mm.

The Vernier Caliper• This instrument may be used to measure
outer dimensions of objects (using the main jaws), inside dimensions (using the smaller jaws at the top), and depths (using the stem).

How to read and use the Vernier Caliper?

The reading here is 3.7 mm or 0.37 cm.
Doc. No : SKF/TR/02 Rev. No : 0 Effective Date : 20.4.11
The reading here is 15.8 mm or 1.58 cm.
Doc. No : SKF/TR/02 Rev. No : 0 Effective Date : 20.4.11
In figure 4 above, the first significant figures are taken as the main scale reading to the left of the vernier zero, i.e. 3.7 cm. The remaining digits are taken from the vernier scale reading that lines up with any main scale reading, (i.e. 0.46 mm or 0.046 cm) on the vernier scale. Thus the
reading is 3.746 cm.Doc. No : SKF/TR/02 Rev. No : 0 Effective Date : 20.4.11
Doc. No : SKF/TR/02 Rev. No : 0 Effective Date : 20.4.11
In figure 6 the zero and the ten on the vernier scale both line up with main scale readings, therefore the reading is 4.000 cm.
