Definitions:

Total Runout

A composite tolerance applied to a feature which controls both its form and its orientation to a datum axis.

Datum Axis

An imaginary line or surface referenced in manufacturing or inspection of parts and assemblies to ensure coordination and correctness of dimension and tolerance specifications.

Circular Runout

A tolerance that controls the uniformity of a feature's surface as it is rotated about a datum axis.

Eccentricity

Eccentricity refers to the degree to which a geometric shape’s center does not align with a reference axis or point, crucial in designing rotating parts to minimize imbalance.
