Geometrical product specifications (GPS) - Dimensioning and tolerancing - Cones (ISO 3040:2016)
This International Standard specifies graphical indication applicable to a cone (right-angle circular
cones) to define its dimensioning or to specify its tolerancing.
For the purposes of this International Standard, the term “cone” relates to right-angle circular cones
only (any intersection by a plane perpendicular to the axis of the nominal cone is a circle).
NOTE 1 For simplicity, only truncated cones have been represented in this International Standard. However,
this International Standard can be applied to any type of cone within its scope.
NOTE 2 This International Standard is not intended to prevent the use of other methods of dimensioning and
tolerancing.
Geometrische Produktspezifikation (GPS) - Maßeintragung und Toleranzfestlegung - Kegel (ISO 3040:2016)
Diese Internationale Norm spezifiziert die Zeichnungseintragungen für einen Kegel (rechtwinklige kreisförmige Kegel) zur Definition seiner Bemaßung oder Spezifikation seiner Tolerierung.
Für den Zweck dieser Internationalen Norm bezieht sich der Begriff „Kegel“ nur auf rechtwinklige kreisförmige Kegel (jeder Schnittpunkt durch eine Ebene senkrecht zur Achse des Nennkegels ist ein Kreis).
ANMERKUNG 1 Zur Vereinfachung wurden nur abgeschnittene Kegel in dieser Internationalen Norm dargestellt. Diese Internationale Norm kann allerdings innerhalb ihres Anwendungsbereiches auf beliebige Kegeltypen angewendet werden.
ANMERKUNG 2 Es ist nicht die Absicht dieser Internationalen Norm, die Verwendung anderer Methoden der Bemaßung und Toleranzfestlegung auszuschließen.
Spécification géométrique des produits (GPS) - Cotation et tolérancement - Cônes (ISO 3040:2016)
ISO 3040:2016 spécifie l'indication graphique applicable à un cône (cônes de révolution) pour définir sa cotation ou pour spécifier son tolérancement.
Pour les besoins de la présente Norme internationale, le terme « cône » se rapporte seulement aux cônes de revolution (toute intersection par un plan perpendiculaire à l'axe du cône nominal est un cercle).
NOTE 1 Dans la présente Norme internationale, seuls les troncs de cônes ont été représentés, ceci à des fins de simplification. Cependant la présente Norme internationale peut s'appliquer à tous types de cônes, dans le cadre de son domaine d'application.
NOTE 2 II n'est pas dans l'intention de la présente Norme internationale d'empêcher l'emploi d'autres méthodes de cotation et de tolérancement.
Specifikacija geometrijskih veličin izdelka (GPS) - Dimenzioniranje in toleriranje - Konusi (ISO 3040:2016)
Ta mednarodni standard določa grafične oznake za konuse (pravokotne krožne konuse), s katerimi se določi dimenzioniranje ali toleriranje.
V tem mednarodnem standardu se izraz »konus« nanaša samo na pravokotne krožne konuse (vsak presek z ravnino pravokotno na os nominalnega konusa je krog).
OPOMBA 1: Zaradi poenostavitve so v tem mednarodnem standardu predstavljeni samo skrajšani konusi, vendar se lahko standard uporablja za katero koli vrsto konusa, ki spada v njegovo področje uporabe.
OPOMBA 2: Ta mednarodni standard ne preprečuje uporabe drugih načinov dimenzioniranja in toleriranja.

Introduction
This International Standard is a geometrical product specification (GPS) standard and is to be regarded
as a general GPS standard (see ISO 14638), applicable to a conical feature. It influences chain links A
and B of the chain of standards on size, form, orientation, location and run-out.
For more detailed information about the relationship of ISO 3040 to other standards and to the GPS
matrix model, see Annex B.
The ISO/GPS matrix model given in ISO 14638 gives an overview of the ISO/GPS system of which this
international standard is a part. The fundamental rules of ISO/GPS given in ISO 8015 apply to this
international standard and the default decision rules given in ISO 14253-1 apply to specifications made
in accordance with this international standard, unless otherwise indicated.
In this International Standard, the figures illustrate the text only and should not be considered as
design examples. For this reason, the figures are simplified and are not to scale.
No indications from the previous edition (ISO 3040:2009) have been made obsolete by this edition.
Therefore, there is no ‘former practice’.

No more dimensions than necessary shall be indicated. However, additional dimensions may be given
for information as auxiliary dimensions.
Some dimensions may be used to establish a tolerancing by dimensional or geometrical specification
(see Clause 6). For this reason these dimensions may be defined as TEDs.
Some typical combinations of cone dimensions are shown in Figure 3, Figure 4, Figure 5 and Figure 6.

5.2 Indication of rate of taper value on drawings
The graphical symbol with the rate of taper value of a cone shall be indicated near the feature according
to the rules presented in Clause 4.
As shown in Figure 7, the reference line attached to the graphical symbol shall be:
— drawn parallel to the cone axis, and
— connected by a leader line to the outline of the cone.
When the taper belongs to a standardized series of conical taper (in particular Morse or metric taper),
the rate of taper value of the cone may be replaced by the codification given by standard series according
to ISO 1119 and appropriate number (see Figure 8). For example, the rate of taper value “1:20,047” may
be replaced by the codification “Morse No. 1”.

6 Tolerancing of a cone
A cone is intrinsically defined by its angle (see Figure 9).
Figure 9 — Intrinsic representation of a cone
NOTE A cone is different from a frustum which is defined by three geometrical entities (one of them is a cone).
EXAMPLE A frustum defined by a cone and two end planes (not necessarily perpendicular to the axis of this
cone). See Figure 10.

Figure 10 — Example
The objective of tolerancing is to define a set of one or more GPS specifications. Each GPS specification
defines a particular characteristic and its permissible extent by the mean of one or two tolerances
limits (see example in Figure 11).
When a gauge plane is used in a specification, the gauge plane location shall be defined by TEDs (explicit
or implicit: 0 mm).

SIST EN ISO 3040:2016
ISO 3040:2016(E)
When a datum or datum system is used to locate or orientate the tolerance zone, the angular or linear
dimensions constraining the tolerance zone shall be defined by TEDs (explicit or implicit:0 mm, 0°, 90 °,
180°, 270°).
When a geometrical specification is applied to a cone with the surface profile characteristic symbol
without datum or datum system and the intrinsic characteristic of the cone shall be taken into account
as fixed, then:
— the symbol VA shall not be indicated in the second compartment of the tolerance frame; and
— the angle of the cone shall be indicated:
— directly with the cone angle as a TED, or
— indirectly with the rate of taper value or by a combination of several dimensions on a cone (e.g.
see Figure 6).
Each characteristic controls a set of degrees of freedom on the real workpiece.
The set of degrees of freedom, which are possible to consider individually or collectively, is:
— the angle deviation;
— the form deviation on a section line or the surface;
— the location deviation (X, Y, Z : in Cartesian system);
— the orientation deviation (β, γ : in Cartesian system).
The table in Figure 11 presents, for a specification, the type of deviations which are controlled.
The indication of the specification is presented and its meaning is illustrated and explained. This
presentation is used in Annex A.
Figure 11 and Annex A present various individual (independent) examples of possible dimensional
or geometrical specifications in relation with a cone, in accordance with ISO 1101, ISO 14405-1 and
ISO 14405-3. Each of these examples
