You just have to add the first part and second part of the measurement to obtain the micrometer reading. Reading a micrometer takes practice.

Micrometer Screw Gauge Working Principle Construction Reading Measurements Extrudesign Micrometer Gauges Screw

In a micrometer the object you wish to measure is clamped between the anvil the stationary end of the clamp and the spindle the moving part of the clamp.

How to read a micrometer. Each line on the thimble or the spinning grip is one-thousandth of an inch 001. Here we are going to learn to read the micrometer by figuring out the markings on the Thimble and the Sleeve. When holding by hand use the palm of your hand and a finger to anchor the frame.

Set zero with the sphere in the center of the anvil faces and zero. The lengths of extension rod and collar are added to the micrometer reading. Holding a Micrometer by Hand Tip.

Count the number of revolutions by pushing dial indicator against the item and hold the gauge to take measurements. What is the measurements on the micrometer shown below. To learn to read the mike you need to understand the Thimble and the Sleeve.

If for example it lines with 1 then the measurement will will read 5261. It looks like a ruler with ten numbers. Use a small sphere or the stylus of a digital probe.

An accurate reading is taken by adding theses three numbers together. To read the metric micrometer first read the number of whole millimeters on the bottom row of the sleeve of the micrometer Figure 3. The Sleeve does not move.

Finally add in the five01 millimeters on the thimble for a total of 655 millimeters. This scale contains the 1mm increment and half mm increment reading. If there is an additional line uncovered on the top row this is equal to one-half a millimeter Figure 3.

Move the ball around the measuring faces and see how the zeroed measurement changes. This type of micrometer is designed for measuring the outside of objectsthe outside diameter OD. Reading the Dial Micrometer Step by Step Displace the spindle and align it with the item to be measured.

The primary scale is located on the sleeve. So 05 mm would need to be added to the measurement. The division on the bottom indicates twenty-five thousandths 0025 of an inch.

It must stay within the micrometers tolerance. However for precise measuring those two and the numbers on the top of the mic will be used. Larger micrometers come with Micrometer Standards.

The number 2 on the top of the spindle indicates two hundredths 020 of an inch. The next step is reading the micrometer. The micrometer on the bottom reads 655mm.

Then add in the one50 millimeter on the other side of the sleeve which equals 650 millimeters. We will have a look at how to use a traditional analog micrometer and how to read the dimension correctly. Read that line that lines closest with the sleeve.

For usual operations those two would be enough. Flip the micrometer over to read to the 10 thousandths marking. Sleeve shows 4 dollars 1 quarter four dollars twenty-five cents 425 Thimble shows 5 cents 005 425 5 430 or _430.

It has a precision of 001 mm and if you ever aspire to make something with tight tolerance you will probably need to use it. To determine the value of the measure it is necessary to add. They look and move much like a C-clamp which opens and closes by turning an internal screw.

This type of micrometer can be read by 0001 mm length. Each line on the micrometer itself is twenty-five thousandths of an inch 025. A micrometer is an essential tool for taking precise measurements.

Basic teaching type video on how to read an Inch micrometer including tenths readings. The micrometer above reads 228 inch. To ensure that you understand the steps above heres one more example.

Reading an Inch-based Micrometer. Reading of the micrometer in thousandth inch by the measurement formation. In order to increase accuracy the vernier principle also is applied to an outside micrometer.

55 028 578 mm. These are the whole millimeters. Start with the six whole millimeters which equals 60 millimeters.

The value obtained in the graved scale in the sleeve in tenths of inch 01in represented by the o in green color in the animation below. The micrometer is then removed and reading is taken.
