20、modification. NOTE: Normative references to international publications are listed in Annex ZA (normative). Introduction This part of IS0 13565 is a Geometrical Product Specification (GPS) standard and is to be regarded as a General GPS standard (see ISO/TR 14638:1995). It influences chain link 2 of

21、the chain of standards for roughness profile. For more detailed information of the relation of this part of IS0 13565 to other standards and the GPS matrix model, see annex A. This part of IS0 13565 defines a set of parameters, based on the linear material ratio curve, to be used for the evaluation

22、of the valley suppressed roughness profile defined in IS0 13565-1. It is based on a three-layer surface model, evaluating the peaks, the core and the valleys separately. Page 3 EN IS0 13565-2 : 1997 1 Scope This part of IS0 13565 describes the evaluation process for determining parameters from the l

23、inear representation of the material ratio curve (also referred to as the Abbott curve) which describe the increase of the material portion of the surface with increasing depth of the roughness profile. They are intended to aid in assessing the operational behaviour of highly mechanically stressed s

Page 4 EN IS0 13565-2 : 1997 3.1 roughness core profile: Roughness profile excluding the protruding peaks and deep

28、 valleys (see figure 1) 3.1.1 core roughness depth, Rk: Depth of the roughness core profile (see figure 1). 3.1.2 material portion, Mrl: Level, in percent, determined for the intersection line which separates the protruding peaks from the roughness core profile. 3.1.3 material portion, Mr2: Level, i

29、n percent, determined for the intersection line which separates the deep valleys from the roughness core profile. 3.2 reduced peak height, pk: Average height of the protruding peaks above the roughness core profile NOTE - The averaging process in clause 4 reduces the effect of outlier values on this

30、 parameter. 3.3 reduced valley depths, vk: Average depth of the profile valleys projecting through the roughness core prof ile. NOTE - The averaging process in clause 4 reduces the effect of outlier values on this parameter. 4 Determination of parameters 4.1 Roughness profile The roughness profile u

31、sed for determining the parameters which are the subject of this part of IS0 13565 shall be calculated according to IS0 13565-1. 4.2 Calculating the parameters k, Mrl , Mr2 The equivalent straight line, calculated according to 4.3, intersects the abscissae Mr= O YO and Mr= 100 ?LO (see figure 1). Fr

32、om these points two lines are plotted to the x-axis, which determine the roughness core profile by separating the protruding peaks and valleys. The vertical distance between these intersection lines is the core roughness depth k. Their intersections with the material ratio curve defines the material

33、 ratios Mrl and Mr2. 4.3 Calculating the equivalent straight line The equivalent straight line is calculated for the central region of the material ratio curve which includes 40 ?Lo of the measured profile points. This “central region” lies where the secant of the material ratio curve over 40 % of t

34、he material ratio shows the smallest gradient (see figure 1). This is determined by moving the secant line for AMr = 40 % along the material ratio curve, starting at the Mr = O % position as in figure 1. The secant line for AMr= 40 % which has the smallest gradient establishes the “central region” o

35、f the material ratio curve for the equivalence calculation. If there are multiple regions which have equivalent minimum gradient, then the one region that is first encountered is the region of choice. A straight line is then calculated for this ”central region” which gives the least square deviation

36、 in the direction of the profile ordinates. NOTE - To ensure the validity of the material ratio curve, the class widths of ordinates of the roughness profile should be selected to be small enough for at least 10 classes to fall within the “central region”. With surfaces having very small roughness o

37、r having an almost ideal geometrical plateau, such a fine classification may no longer be meaningful, because of the limited resolution of the measuring system. In this case the number of classes used in the calculation of the equivalent straight line should be stated in the test results. Page 5 EN

The parameters Rpk and Rvk are each calculated as the height of the right-angle triangle which is constructed to have the same area as the “peak area“ or “valley a
