25、BS EN ISO 3040:2016ISO 3040:2016(E)IntroductionThis 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

26、, 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 fun

27、damental 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

28、 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. ISO 2016 All rights reserved vBS EN ISO 30

29、40:2016BS EN ISO 3040:2016Geometrical product specifications (GPS) Dimensioning and tolerancing Cones1 ScopeThis 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 I

30、nternational 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 Stan

31、dard 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.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indi

32、spensable for its application. For dated references, only the edition cited applies.

34、tween themNote 1 to entry: lt is expressed by the following formula (see also Figure 1).CDdL=22tan(1)Figure 1INTERNATIONAL STANDARD ISO 3040:2016(E) ISO 2016 All rights reserved 1BS EN ISO 3040:2016ISO 3040:2016(E)4 Graphical symbol for a rate of taper for a coneA rate of taper for a cone shall be i

35、ndicated using the graphical symbol illustrated in Figure 2 centred on a reference line (see Figure 7). The orientation of the graphical symbol shall coincide with that of the cone (see Figure 7 and Figure 8).Size and line thickness of the graphical symbol are according to ISO 81714-1.Figure 25 Dime

36、nsions and indication on a cone5.1 Dimensions on a coneSeveral kinds of dimensions as shown in Table 1 may be used in order to define a cone.Table 1 Dimensions on a coneType of dimensions Letter symbol Examples of indicationPreferred method Optional methodRate of taper valueC1:51/50,2:120 %Cone angl

38、 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 TED

39、s.Some typical combinations of cone dimensions are shown in Figure 3, Figure 4, Figure 5 and Figure 6.2 ISO 2016 All rights reservedBS EN ISO 3040:2016ISO 3040:2016(E)Figure 3Figure 4Figure 5 ISO 2016 All rights reserved 3BS EN ISO 3040:2016ISO 3040:2016(E)Figure 65.2 Indication of rate of taper val

40、ue on drawingsThe 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 li

41、ne 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 exam

42、ple, the rate of taper value “1:20,047” may be replaced by the codification “Morse No. 1”.Key1 leader line2 rate of taper graphical symbol3 reference lineNOTE 1:5 is the rate of taper value.Figure 74 ISO 2016 All rights reservedBS EN ISO 3040:2016ISO 3040:2016(E)Figure 86 Tolerancing of a coneA cone

43、 is intrinsically defined by its angle (see Figure 9).Figure 9 Intrinsic representation of a coneNOTE 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

44、 axis of this cone). See Figure 10.Key1 Plane 12 Plane 23 coneFigure 10 ExampleThe 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 exa

45、mple 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). ISO 2016 All rights reserved 5BS EN ISO 3040:2016ISO 3040:2016(E)When a datum or datum system is used to locate or orientate the tolerance zone, the angul

46、ar 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 co

47、ne 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 dimensi

48、ons 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 devi

49、ation (X, Y, Z : in Cartesian system); the orientation deviation (, : 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 11
