Orientation tolerance · ISO 1101
Angularity
Limits how far a feature may deviate from a stated angle (other than 90 degrees) to a datum.
In the shop
The angle comes from the setup, so a sine fixture or a controlled tilt matters more than cutting parameters. Confirm the angle on the finished part.
General shop guidance in our own words. The drawing and the standard it cites decide; verify on a sample part.

Ask about your drawing
Tell the advisor the feature, the tolerance on the drawing and the material. It answers with machining choices, brand-neutral.
