10 Concentricity and Symmetry

Readers will learn:

1. Apply and measure concentricity using differential measurements.

2. State the advantages and disadvantages between coaxiality-type controls, including: position, concentricity, circular runout and total runout.

3. Explain the differences between positional coaxiality and concentricity.

4. Design and dimension a functional gage for positional coaxiality.

5. Apply and measure symmetry.
