Geometric tolerancing controls geometric characteristics of parts such as circularity, runout, position, etc.

Geometric Tolerancing

A system that defines and specifies engineering tolerances based on geometric shapes and features, improving interchangeability and quality.

Circularity

A geometric tolerance that limits the deviation of an object’s form from being a perfect circle.

Runout

A term that describes the maximum deviation or variation of an object from its intended perfect form or the total movement of a rotational part.
