This part of JIS B 0671 defines a set of parameters, based on the linear material ra- tio curve, to be used for the evaluation of the
15、valley suppressed roughness profile de- fined in JIS B 0671-1. It is based on a three-layer surface model, evaluating the peaks, the core and the valleys separately. “Informations” underlined with dots in this Standard are the matters not included in the original International Standard. Remarks : TR
16、 B 0007 is identical with ISO/TR 14638 : 1995 Geometrical Product Specifications (GPS) - Masterplan. Information : A triple stratified surface model is a profile model that the profile con- sists of three independent random processes of a protruding peak to the height direction, a core and a reduced
17、 valley. _L_-. 1 Scope This part of JIS B 0671 describes the evaluation process for determining parameters from the linear 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
18、 roughness profile. They are intended to aid in assessing the operational behaviour of highly mechanically stressed surfaces. Remarks : The International Standard corresponding to this Standard is as follows. In addition, symbols which denote the degree of correspondence in the contents between the
19、relevant International Standard and JIS are IDT (identical), MOD (modified), and NEQ (not equivalent) according to ISO/IEC Guide 21.

35、ve which includes 40 % of the measured profile points. This “central region” lies where the secant of the material ratio curve over 40 % of the material ratio shows the smallest gradient (see figure i). This is de- termined by moving the secant line for AMr = 40 % along the material ratio curve, sta
36、rting at the Mr = O % position as in figure 1. The secant line for dMr = 40 % which has the smallest gradient establishes the “central region” of the material ratio curve for the equivalence calculation. If there are multiple regions which have equivalent minimum gradient, then the one region that i
37、s first encountered is the region of choice. A straight line is then calculated for this “central region” which gives the least square deviation 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 profil
38、e should be selected to be small enough for at least 10 classes to fall within the “central region”. With surfaces having very small roughness or having an almost ideal geometrical plateau, such a fine classifi- cation may no longer be meaningful, because of the limited resolution of the measuring s
39、ystem. In this case the number of classes used in the calculation of the equivalent straight line should be stated in the test results. Information : “Secant line” is a straight line which intersects a curve at two or more The difference between the material ratio curves (%) is positions. “AMY. - _-
40、_. 4.4 Calculating the parameters Rpk and Rvk The areas abve and below the region of the material ratio curve which delimits the core roughness Rk are shown hatched in figure 1. These correspond to the cross-sectional area of the profile peaks and valleys which protrude out of the roughness core pro
41、file. 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 area” respectively (see figure 2). The right-angle triangle corresponding to the “peak area Al” has Mrl as its base, and that corres
42、ponding to the “valley area A2” has 100 %-Mr2 as its base. Note : The parameters according to this part of JIS B 0671 should only be calculated if the material ratio curve is “S” shaped as shown in figures 1 and 2 and thus has only one single point of inflection. Experience has shown that this is al
43、- ways the case for lapped, ground or honed surfaces.
