1. Original Power Point Created by Scott Sommerlatte Modified by Georgia Agricultural Education Curriculum Office May 2007

2. Why do we use measuring tools? What tools will we use? How do we read measuring tools? Where are these tools used in industry?

3. Make measurements with dial calipers, and micrometers Complete a worksheet on measuring tools

4. Measuring “jigs” before starting a job While working on a job To check dimensions after completing a job

6. Accuracy of.001” 0” – 6”, 0” – 12”, 0” – 36” Used on precision jobs Measures Outside Diameters, Inside Diameters, And Depths

8. 1.Dial 2.Jaws 3.Nibs 4.Bar 5.Clamp Screw

9. Each increment on the bar represents.100” Each round on the dial equals.100” or.200” Depending on the brand of the tool Bold numbers on the dial represent.010” Small dashes equal.001”

10. Most accurate Accuracy of.0001” Available in various sizes, from 0” – 1” up to 35” – 36” Used to measure Outside Diameters
