4.2.553 Total_runout_tolerance

A Total_runout_tolerance is a geometric constraint on a cylindrical surface with respect to a datum axis the part is rotated about. The tolerance is applied simultaneously to all positions as the part is rotated 360 degrees.

NOTE 1 Where applied to surfaces constructed around a datum axis, Total_runout_tolerance is used to control cumulative variations of circularity, straightness, coaxiality, angularity, taper, and profile of a surface.

NOTE 2 Where applied to surfaces constructed at right angles to a datum axis, Total_runout_tolerance controls cumulative variations or perpendicularity and flatness.

A Total_runout_tolerance is a type of Geometric_tolerance.

The data associated with a Total_runout_tolerance are the following:

4.2.553.1 angle

The angle specifies the direction with respect to the datum axis in which a runout tolerance is controlled.

If the angle is specified the runout tolerance applies for this angle. If the angle is not specified the runout tolerance applies normal to the feature surface.

The angle need not be specified for a particular Total_runout_tolerance.

4.2.553.2 reference_datum

The reference_datum specifies the Datum_reference objects that define the reference for this type of geometric tolerance.

See total_runout_tolerance to datum_reference for the application assertion.
