Definitions:

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.

Cylindricity

A form tolerance that defines how much a cylindrical feature's actual profile may deviate from a perfect cylinder.

Total Runout

Total runout is a tolerance that controls the total variation a surface can have when it is rotated around an axis or datum.

Datum Axis

An imaginary line defined by the geometric center or specified points of a feature, used as a reference or starting point for measurements and geometric definitions.
