10、SO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical c
11、ommittee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electr

26、olerance3 Terms and definitionsFor the purposes of this document, the following terms and definitions apply. ISO 2015 All rights reserved 1BS ISO 10110-19:2015ISO 10110-19:2015(E)3.1general surfaceany surface including those free from constraints of symmetry and/or formNote 1 to entry: A general sur
27、face can be both a continuous as well as a discontinuous surface. It can contain local regular geometrical properties. In principle, any surface (e.g. conic sections, including the sphere) can be described by this part of ISO 10110 as a general surface. ISO 10110-12 offers a formalized and specific
28、mathematical approach that is a more direct approach. The simplest description that fulfils the given requirements shall be used.3.2reference axistheoretical axis given by the optical designer which does not depend on symmetries of the surface and which usually represents the centre of the optical p
29、ath for the main functionNote 1 to entry: It should ensure a minimum of tolerance influence and enhance the flexibility for production. The reference axis cannot be changed and is defined once. The position and orientation of the reference axis is defined by measurable references at and/or on the ge
30、neral surface/component or by an approximation of the nominal surface.3.3transport formatsfile formats for transfer of data between software systems and processing and measuring machinesEXAMPLE Typical transport formats are XML and STEP.4 Referencing4.1 GeneralThe general surface is referenced with
31、the coordinate systems used in the process chain, e.g. to define centring tolerances according to ISO 5459. A general surface can have 3 essential coordinate systems as shown in Figure 1: the origin of the mathematical description; the reference coordinate system at the intersection of reference axi
32、s and surface; the component reference points.NOTE If the origin of the mathematical surface description is out of the used surface area, it can be useful to provide two separated reference axes; one reference axis for the production (e.g. fast tool servo machining axis) and one reference coordinate
33、 system for measuring. Although both coordinate systems have geometric meaning, they are not physical and thus useful to be referenced by the component reference points. The referencing establishes a clear reference of the general surface, both to coordinate systems of processing machines and measur
34、ing devices as well as higher-level assemblies.For referencing, specifications shall be available for the clear orientation of the general surface according to its position and direction (6 degrees of freedom) relative to component reference points. For referencing planes, cylinders, cones, or spher
35、es shall be included. Reference marks in the form of crosses, circles, or lines and combinations of the specified structures can also be used. The references may be in any position on the work piece. An example is illustrated in Figure 1.2 ISO 2015 All rights reservedBS ISO 10110-19:2015ISO 10110-19

38、ure 1 Off-axis asphere drawn as general component with reference structures4.2 Coordinate systemThe coordinate system is in three axes (X, Y, Z) orthogonal to each other and follows the right hand rule (right-handed system). The coordinate origin should be on the reference axis and the general surfa
39、ce (see Figure 2). In this case, the Z-axis of the coordinate system will represent the reference axis. Once defined, the position and orientation of the coordinate system shall not be changed.Unless otherwise specified, the Z-axis is in the plane of the drawing and runs from left to right. If only
40、one cross-section is drawn, the Y-axis is in the plane of drawing and is oriented upwards.If two cross-sections are drawn, the XZ cross-section shall appear below the YZ cross-section. For clarity, the X and Y axes can be shown on the drawing.4.3 Sign conventionAs laid down in later clauses of this
41、part of ISO 10110, the various general surfaces are specified by mathematical equations or vectors. To achieve clear surface specifications, the following sign conventions for the constants, vectors, and coefficients shall be used.The sagitta of a point on the general surface is positive if it lies
42、in the positive Z direction from the XY plane and negative if it lies in the negative Z direction from the XY plane. ISO 2015 All rights reserved 3BS ISO 10110-19:2015ISO 10110-19:2015(E)5 Drawing specifications5.1 GeneralA general surface shall be represented in the same manner as a spherical compo
43、nent (see ISO 10110-1). The specification of the radius of curvature shall be replaced by the abbreviation “GS” (for “General Surface”).The origin of the general surface shall be specified on the drawing.The component references shall be marked and dimensioned to the coordinate system of the general
44、 surface.The general surface may be represented in an exaggerated manner on the drawing to illustrate these factors. The part shall be marked accordingly. In addition, the drawing shall contain a sagitta table (see Table 1). It shall allow the point-by-point testing of the transferred surface form o
45、n the basis of Cartesian coordinates or Polar coordinates for Z, the sagitta, and S, the surface slope. The required accuracy and uniformly complete distribution shall be ensured in the point-by-point testing method. In addition to the sagitta, the slope is specified as a control value.Table 1 Examp
