DIN EN ISO 12180-2:2011-07 EN ISO 12180-2:2011 (E) 3 Introduction This part of ISO 12180 is a geometrical product specification (GPS) standard and is to be regarded as a general GPS standard (see ISO/TR 14638). It influences chain link 3 of the chain of standard

29、s on form of a surface (independent of a datum). The ISO/GPS Masterplan given in ISO/TR 14638 gives an overview of the ISO/GPS system of which this part of ISO 12180 is a part. The fundamental rules of ISO/GPS given in ISO 8015 apply to this part of ISO 12180 and the default decision rules given in

30、ISO 14253-1 apply to specifications made in accordance with this part of ISO 12180, unless otherwise indicated. For more detailed information on the relationship of this part of ISO 12180 to other standards and the GPS matrix model, see Annex C. This part of ISO 12180 specifies the specification ope

31、rators according to ISO 17450-2 for cylindricity of integral features. At the time of publication of this part of ISO 12180, ISO/TC 213 has not been able to reach consensus on defaults for filter undulation per revolution (UPR), probe tip radius and method of association (reference cylinder). This m

32、eans that it is necessary for a cylindricity specification to explicitly state which values are intended for use with these specification operations in order for it to be unique. Consequently, if a specification does not explicitly state which values are to be used for one or more of these operators

33、, the specification is ambiguous (see ISO 17450-2) and a supplier can use any value for the operator(s) not specified when proving conformance. Extracting data always involves applying a certain filtering process. An additional filtering of the extracted data might or might not be applied. This addi

34、tional filter can be a mean line filter (Gaussian, spline, wavelet, etc.) or a non-linear filter (e.g. morphological filter). The type of filtering influences the definition of cylindricity and the specification operators and, therefore, needs to be stated unambiguously. NOTE 1 Stylus filtering is n

35、ot sufficient on its own to smooth a profile. In certain circumstances, it can create spurious high-frequency content, thus giving incorrect values. To correct this, a longwave pass filter is employed. A Gaussian filter is used, since this is the state-of-the-art in International Standards. This fil

36、ter has some shortcomings, e.g. it can distort, rather than eliminate some roughness features and it can distort, rather than transmit correctly some waviness features. It is envisioned that new filters under development within ISO provide better solutions for several of these issues. NOTE 2 If a sm

37、aller tip radius than the one specified is used for a given cut-off length, the resulting measured value is generally higher. This effect is usually insignificant. If a larger tip radius is used, the resulting measured value is generally lower. The amount of change is heavily dependent on the surfac

38、e measured. NOTE 3 The measuring force of 0 N is chosen to eliminate effects of elastic deformation of the workpiece from the specification operator. On metal surfaces with adequate thickness, the effect of normally occurring measuring forces is negligible. NOTE 4 Aliasing and other problems during

39、extraction (see Annex A) due to the higher harmonic content of the skin model, in the roundness and straightness directions, can cause specification uncertainty. This part of ISO 12180 is not intended to disallow any means of measuring cylindricity. DIN EN ISO 12180-2:2011-07 EN ISO 12180-2:2011 (E)

The

46、complete specification operator defines the transmission band for the cylindricity surface, together with an appropriate stylus tip geometry. NOTE In practice, it is unrealistic to hope to achieve comprehensive coverage of the cylindrical feature given by the theoretical minimum density of points (s

47、ee Annex B) within an acceptable time span using available technology. Therefore, more limited extraction strategies are employed that give specific, rather than general, information concerning the deviations from cylindrical form. 4.2 Probing system 4.2.1 Probing method A contacting probing system

48、with a stylus tip, as defined in 4.2.2, is part of the specification operator. 4.2.2 Stylus tip geometry The theoretically exact stylus tip geometry is a sphere. 4.2.3 Probing force The probing force is 0 N. 5 Compliance with the specification For proving conformance or non-conformance with the spec
