Verifying the Roundness of A Circle
A circle is a two-dimensional geometric shape that can be defined by
- the center and the radius,
- the diameter,
- and by three points located along the circumference, i.e., the circular line.
When checking the roundness, an optical 3D measuring system captures several points along the circumference. These measuring points do not have to be within the same plane but can be projected onto the circle plane during the analysis. There are two ways to check the roundness of a circle:
- Comparing and matching with the geometry of an existing circle.
- Averaged circumference between the measured points.
The result specifies in which tolerance field the points are located along the circumference or produces a diagram with the visualized deviations.
