5.1 General

With cones, the following characteristics may be toleranced:

• surface profile (form) of the cone (conicity);

• orientation and radial location of the cone (cone axis) relative to a datum;

• axial location of the cone relative to a datum;

• distance of an end face of the truncated cone relative to another face.

The first three characteristics (deviations) may be toleranced either together (in common) by the profile tolerance of the cone ( t in Fig. 5.3), or separately by different tolerances (Figs 5.4 to 5.10).

The cone angle may be specified as the theoretically exact angular dimension or...
