>Hello Sohib EditorOnline, in this article, we will discuss the steps to determine the measurements using a micrometer screw gauge or mikrometer sekrup in Indonesian language. It is a precision instrument used for measuring the thickness, diameter, and length of small objects with high accuracy. This article will provide a comprehensive guide on how to use a micrometer screw gauge and calculate the measurements with ease. Let’s dive in!

What is a Micrometer Screw Gauge?

A micrometer screw gauge or mikrometer sekrup is a measuring instrument that consists of a calibrated screw that rotates with a thimble containing a circular scale. The screw advances by a fixed distance for each rotation of the thimble. The micrometer screw gauge is used to measure the thickness, diameter, and length of small objects with high accuracy. The instrument is commonly used in mechanical engineering, metalworking, and other fields that require precise measurements.

The micrometer screw gauge consists of two jaws, one fixed and one movable, that are used to hold the object being measured. The jaws are moved by turning the thimble, which rotates the screw. The measurement is taken by reading the scales on the thimble and the barrel.

How to Use a Micrometer Screw Gauge?

Using a micrometer screw gauge requires precision and accuracy. Following the steps below will ensure that you get accurate readings:

Step 1: Clean the Micrometer Screw Gauge

The first step is to ensure that the micrometer screw gauge is clean and free of debris. This ensures that the instrument is accurate and will provide correct measurements.

To clean the micrometer screw gauge, wipe the jaws and the anvil with a clean cloth. Avoid touching the measuring surfaces with your fingers, as it can leave oil that can affect the accuracy of the instrument.

Step 2: Select the Object to be Measured

Select the object that you want to measure. The object should fit between the jaws of the micrometer screw gauge. Ensure that the object is clean and free from any debris that can affect the measurement.

Step 3: Open the Jaws and Place the Object

Open the jaws of the micrometer screw gauge and place the object between the jaws. Use your fingers to hold the object in place.

Step 4: Close the Jaws

Gently close the jaws until they make contact with the object. Avoid applying too much force, as it can affect the accuracy of the measurement.

Step 5: Take the Measurement

Read the scales on the thimble and the barrel to determine the measurement. The measurement is the sum of the value on the barrel and the value on the thimble multiplied by the least count of the instrument. The least count is the smallest measurement that the instrument can read.

Step 6: Record the Measurement

Record the measurement in your notes or on a piece of paper. Ensure that you label the measurement with the unit of measurement.

How to Calculate Measurements Using a Micrometer Screw Gauge?

Calculating measurements using a micrometer screw gauge requires knowledge of the instrument’s least count and how to read the scales. The formula for calculating the measurement is:

Measurement = (Value on the Barrel + Value on the Thimble x Least Count)

For example, if the value on the barrel is 2.5 mm and the value on the thimble is 0.25 mm, and the least count of the instrument is 0.01 mm, the measurement is:

Measurement = (2.5 mm + 0.25 mm x 0.01 mm)

Measurement = 2.75 mm

FAQ

Q: What is the least count of a micrometer screw gauge?

A: The least count of a micrometer screw gauge depends on the instrument. It can range from 0.001 mm to 0.1 mm depending on the instrument’s accuracy.

Q: How do I read the scales on a micrometer screw gauge?

A: The scales on a micrometer screw gauge are read by aligning the markings on the thimble with the markings on the barrel. The value on the thimble is added to the value on the barrel, and then multiplied by the least count of the instrument.

Q: What is the accuracy of a micrometer screw gauge?

A: The accuracy of a micrometer screw gauge depends on the instrument’s least count. The higher the least count, the more accurate the instrument.

Q: What is the range of measurements that can be taken using a micrometer screw gauge?

A: The range of measurements that can be taken using a micrometer screw gauge depends on the instrument. It can range from 0 mm to 100 mm or more, depending on the instrument’s design and accuracy.

Conclusion

In conclusion, using a micrometer screw gauge is essential in getting accurate measurements of small objects. Following the steps outlined in this article will ensure that you get accurate readings. Remember to clean the instrument before use, select the object to be measured, open the jaws and place the object, close the jaws, take the measurement, and record the measurement. Understanding how to calculate measurements using the instrument is also crucial in getting accurate readings. Use the formula discussed above to calculate measurements with ease. We hope that this article has been helpful in providing a comprehensive guide to using a micrometer screw gauge.
