NOTE 2 The mechanical surface is an essential characteristic of a skin mo
30、del of a workpiece. 3.1.2 electromagnetic surface surface obtained by the electromagnetic interaction with the skin model of a workpiece (3.1) NOTE 1 Different wavelengths give different surfaces. NOTE 2 The electromagnetic surface is an essential characteristic of a skin model of a workpiece. NOTE
31、3 Examples of electromagnetic surface include optical surfaces from coherence-scanning interferometers, optical stylus instruments and scanning confocal microscopes. 3.2 real surface of a workpiece set of features which physically exist and separate the entire workpiece from the surrounding medium I
32、SO 14660-1:1999, 2.4.1 NOTE Real surfaces of workpieces have many potential functional uses, from bearing surfaces in roller bearings to visual appearance in car body panels. At the atomic level, these different functions define different real surfaces, depending on the nature of the functional inte
33、raction with the surface. Since nanoscale measurement is becoming increasingly important economically, there is a requirement to differentiate between these different functional surfaces. The mechanical surface and the electromagnetic surface, defined below, are two commonly used functional surfaces
34、. 3.2.1 real mechanical surface boundary of the erosion, by a sphere of radius r, of the locus of the centre of an ideal tactile sphere, also with radius r, rolled over the real surface of a workpiece (3.2) NOTE 1 Erosion is a morphological operation (see ISO/TS 16610- 40). NOTE 2 The real mechanica
35、l surface is a specific type of real surface of a workpiece. 3.2.2 real electromagnetic surface surface obtained by the electromagnetic interaction with the real surface of a workpiece (3.2) NOTE 1 The locus of the effective ideal reflection point can be affected by both the topographical surface an
36、d the material properties of the workpiece. NOTE 2 Different wavelengths give different surfaces. NOTE 3 The real electromagnetic surface is a specific type of real surface of a workpiece. 3.3 integral feature surface or line on a surface NOTE An integral feature is intrinsically defined.

38、TS 16610-1:2006, 3.1.1 NOTE In practice, the integral surface will be either an integral feature (3.3) or a real (integral) feature (3.3.1). 3.4 primary mathematical model set of nested mathematical representations of the surface portion (3.3.2), wherein each representation in the set can be describ
39、ed by a finite number of parameters ISO/TS 16610-1:2006, 3.2 3.4.1 nesting index NI number, or set of numbers, indicating the relative level of nesting for a particular primary mathematical model (3.4) NOTE 1 Given a particular nesting index, models with lower indices contain more surface informatio
40、n, whereas models with higher nesting indices contain less surface information. NOTE 2 By convention, as the nesting index approaches zero (or a series of all zeros), there exists a primary mathematical model that approximates the real surface of a workpiece to within any given measure of closeness.
41、 ISO/TS 16610-1:2006, 3.2.1 3.4.2 degrees of freedom primary mathematical model number of independent parameters required to fully describe a particular primary mathematical model (3.4) ISO/TS 16610-1:2006, 3.2.2 3.5 primary surface PS surface portion (3.3.2) obtained when the latter is represented
42、as a specified primary mathematical model (3.4) with specified nesting index (3.4.1) ISO/TS 16610-1:2006, 3.3 3.6 primary mapping PM( | NI) mapping indexed by the nesting index (3.4.1), used to identify a particular primary surface (3.5) with the specified nesting index, in order to represent a surf
43、ace portion (3.3.2) that satisfies the sieve and projection criteria NOTE The primary mapping is defined in terms of mathematical mappings as PS = PM(SP | NI) EN ISO 14406:2010 (E) DIN EN ISO 14406:2011-04 7where PS is the primary surface; SP is the surface portion.

44、ary extracted surface finite set of data points sampled from the primary surface (3.5) NOTE 1 The primary extracted surface represents the basis for digital processing by means of surface filters and the calculation of characterization parameters. NOTE 2 Here, “extracted” is used only for objects co
45、ntaining a finite number of data points. Thus the primary surface is still a continuous surface and the primary extracted surface contains a finite number of data points sampled from the primary surface. 3.7.1 reconstruction method of choosing a particular primary mathematical model (3.4), of a fixe
46、d nesting index (3.4.1), that passes exactly through the primary extracted surface (3.7) NOTE 1 The concept of “exact reconstruction” is described in 4.2. NOTE 2 With many primary mathematical models, if the number of sampled points is greater than or equal to the number of degrees of freedom, there
47、 exists a sampling scheme by which the primary surface can be reconstructed without any loss of information from the primary extracted surface (this generalizes the Nyquist criterion). 3.7.2 sampling aliasing two or more primary mathematical models (3.4), of a fixed nesting index (3.4.1), passing ex
48、actly through the primary extracted surface (3.7) NOTE 1 This can cause real problems if the two or more primary mathematical models are very different from each other. NOTE 2 The aliasing is the incorrect reconstruction of a signal due to the overlap of the transfer functions of the filter in a filter bank. 3.8 extraction specification operation that results in a primary extracted surface (3.7) as an approximate representation of the skin model of a workpiece (3.1) 3.9 physical extrac
