There are many different tools available for making precision measurements. The right tool depends on the type of measurement and the required precision. This module will discuss the purpose and use of micrometers, calipers, dial indicators, feeler gauges, and gauge blocks.

Learning Objectives

  • Explain decimal numbers and place values
  • List common precision measuring tools and describe common uses for each
  • Describe the different types of measurement
  • Describe how to use and read micrometers, calipers, dial indicators, feeler gauges, and gauge blocks
  • List guidelines for the proper handling and care of precision measuring tools

Key Questions

The following key questions are answered in this module:

What is a micrometer?
A micrometer is a device that is capable of accurately measuring the distance between two points within one ten-thousandth of an inch.

What are calipers used for?
Calipers are used to measure an object's dimensions, similar to micrometers. Calipers are less accurate than micrometers, but they are more versatile.

What are dial indicators used for?
Dial indicators are used for relative measurements. They amplify small distance or angle measurements to make it easy to quantify.

What are feeler gauges used for?
Feeler, or thickness, gauges are used to measure small gaps, such as the clearance between two parts.

What are gauge blocks used for?
Gauge blocks are metal or ceramic blocks that have been precision ground to a specific thickness. They can be used as standards to calibrate precision measuring tools.

Sample Video Transcript

Below is a transcript of the video sample provided for this module:

Precision measuring tools must be handled with care to maintain their accuracy. If treated properly, these tools can provide years of reliable service. Precision tools should be kept clean and lubricated. Clean before and after each use to prevent rust and ensure accurate measurements. Wipe off dirt, sweat, and fingerprints with a soft cloth. Precision instruments should be lightly oiled after each use to prevent corrosion. Wipe excess oil with a clean, dry cloth because small dirt particles can stick to the oil and cause damage to internal parts. Finally, always store precision instruments in a protective case or in a way that vibration, moisture, and contact with other tools or objects is avoided.
