13.1 Scope - This section specifies methods of diameters of two sections of a cone to their distance.
dimensioning and tolerancing cones on drawings.

13.2 Definitions and Symbols

13.2.1 Taper - The ratio of the difference in the

D-d
TlU.6 taper C =L = 2 tan 5

(see Fig. 13.1).
-

a -- ‘b --_

1,

FIG. 13.1

13.2.2 The following symbol indicates a taper and,

7
rrectly oriented, may be used to show the direction

o the taper (see below).

NOTE - Taper (as defmed above) shall not be confused

with slope.

Slope, which is not the subject of this guide, is the inclination
of the line representing the inclined surface of a wedge
expressed as the ratio of the differences in the heights at right
angles to the base line, at a specified distance apart, to that
distance.

H -- h

Thus slope - __ - tan I3 (see Fig. 13.2).

L

If necessary the following symbol for slope may be used to
show the direction of the slope :

L

FIG. 13.2

13.3 Dimensioning

13.3.1 The following dimensions may be used, in
different combinations, to define the size, form and
position of cones:

a) the taper, specified either by the included angle
or as a ratio, for example:

- 0.3 rad
- 39
- 1:s
-- 0.2: 1.
- 20 % (see Fig. 13.10)
