At the end of the lesson, you should be able to: State the use of a micrometer screw gauge Master the techniques in using a micrometer screw gauge Read the readings on the micrometer screw gauge
4
Use to measure a precise measurement of small distances. Use to measure distance of thicknesses up to 0.01 mm.
5
List of parts of a Micrometer Screw Gauge Anvil Spindle SleeveThimble Ratchet Lock Frame
6
In mechanical engineering & machining. It is used anywhere when we needed to measure small distances.

8
Linear scale (1 mm interval) Lower linear scale (0.5 mm interval) Rotating scale (50 mm interval)
9
Firstly, check for the zero error.
10
Read the reading on the linear scale reading and add with coinciding circular scale multiply by least count. Reading = Linear scale reading + (Coinciding circular scale x Least count) = 2.5 mm + (46 x 0.01) = (2.5 + 0.46) mm = 2.96 mm
