Dimensioning tapers

The size, form, and position of a tapered feature can be defined by calling for a suitable combination of the following:

1 the rate of taper, or the included angle;

2 the diameter or width at the larger end;

Dimensioning two mating tapers

When the fit to a mating part or gauge is necessary, a tried and successful method used in manufacturing units is to add the following information to the feature(s).

When note 2 is added to the drawing, this implies that a 'standard rubbing gauge' will give an acceptable even marking when 'blued'. The functional requirement whether the end-wise location is important or not, will determine the method and choice of dimensioning.

An example of dimensioning two mating tapers when end-wise location is important is shown in Fig. 14.21.

For more accurate repeatability of location, the use of Geometric Tolerancing and a specific datum is recommended. Additional information on this subject may be found in BS ISO 3040.
