Definitions:

Cylindricity

A three-dimensional geometric tolerance that specifies how much a cylindrical feature's actual profile can deviate from a perfect cylinder.

Circularity

Circularity is a geometric tolerance that specifies how much a feature's shape can deviate from a perfect circle.

Parallelism

A geometric condition where surfaces or lines are equidistant at every point, typically referenced in engineering to describe alignment accuracy.

Concentricity

The characteristic of two or more forms sharing a common center, axis, or curve, often critical for mechanical parts that rotate.
