What is difference between circularity and runout

Question

Accepted Answer

Circularity refers to the overall roundness of a feature, while runout refers to the amount of wobble or variation in a feature's position relative to a reference axis.

Circularity is a 2D tolerance that controls the overall roundness of a feature, ensuring it is within a specified circular boundary.
Runout is a 3D tolerance that measures the amount of wobble or variation in a feature's position relative to a reference axis.
Circularity is typically used for features like holes or cylinders, while runout is used for features like shafts or gears.
Circularity is measured by comparing the actual feature to a perfect circle, while runout is measured by comparing the feature's position to a reference axis.
Both circularity and runout are important for ensuring proper fit and function of mechanical components.
