Roundness measurements, Measurements of roundness require 360° traces of the workpiece made with a turntable-type instrument or a stylus-type instrument.
Measure the Roundness (RONt)

The roundness form tolerance measures the deviation of a measured circle to a geometrically ideal circle, at the same centre point.

The roundness is the value obtained by dividing the difference between the maximum and minimum values by 2. A micrometer is all that is needed for measurement.
Roundness

Roundness is generally measured by rotation of the pick-up or workpiccc round a precisely generated axis (Fig. 2.10). Variations in the radius of the workpiece are plotted on a polar chart on which can be superposed a least-squares reference circle from w
