How is angularity specified?

How is angularity specified?

• A. A tolerance on the angle between a feature axis and a datum plane, typically given in degrees.
• B. A tolerance on the distance between two features along an axis.
• C. A tolerance on the surface finish along the axis.
• D. A tolerance on the circular runout around the axis.

Answer: (A)

Angularity deals with how the orientation of a feature’s axis is allowed to tilt relative to a reference datum plane (or datum axis). The tolerance is expressed as an angular value, typically in degrees, signifying how much the axis can deviate in angle from the reference orientation. This focuses on orientation, not position, surface finish, or circular deviation. The other options describe distance along an axis, surface roughness, or circular runout around the axis, which are different types of tolerances.
