13、the material probability curve published in 1998 without modifying the tech- nical contents. This part of JIS B 0671 is a geometrical product specification (GPS) standard and is to be regarded as a general GPS standard (see TR B 0007). It influences the chain link 2 of the chains of standards on rou
14、ghness profile and primary profile. For more detailed information on the relation of this Standard to the GPS matrix model see annex E. This part of JIS B 0671 provides a numerical characterization of surfaces consisting of two vertical random components, namely, a relatively coarse “valley” texture
15、 and a finer “plateau” texture. This type of surface is used for lubricated, sliding contact, for example in cylinder liners and fuel injectors. The calculations necessary to determine the parameters Rpq, Rvq, and Rmq (Ppq, Pvq, and Pmq) used to characterize these two components separately involves
16、the generation of the material probability curve, the determination of its linear regions, and the linear regressions through these regions. The parameters are undefined for surfaces not consisting of two such components. “Informations” underlined with dots in this Standard are the matters not inclu
17、ded in the original International Standard. Remarks TR B 0007 is identical with ISO/TR 14638 : 1995 Geometrical Product Specifications (GPS) - Masterplan. 1 Scope This part of JIS B 0671 establishes the evaluation process for determining parameters from the linear regions of the material probability
18、 curve, which is the Gaus- sian representation of the material ratio curve. The parameters are intended to aid in assessing tribological behaviour, for example of lubricated, sliding surfaces, and to con- trol the manufacturing process. Remarks The International Standard corresponding to this Standa
19、rd is as follows. In addition, symbols which denote the degree of correspondence in the contents between the relevant International Standard and JIS are IDT (identical), MOD (modified), and NEQ (not equivalent) according to ISO/IEC Guide 21.

37、ofile. 3.4 Rmq (Pmq) parameter relative material ratio at the plateau to valley intersec- tion (see figure 2) 4 Procedure The roughness profile used for determining the parameters Rpq, Rvq and Rmq shall be calculated in accordance with JIS B 0671-1. This roughness profile is different from that in J
38、IS B 0601. The profile for determining the parameters Ppq, Pvq and Pmq shall be the primary profile. Three non-linear effects can be present in the material probability curve as shown in figure 1 for measured surface data from a two-process surface. These effects shall be eliminated by limiting the
39、fitted portions of the material probability curve, using only the statistically sound, Gaussian portions of the material probability curve excluding a number of influences. In figure 1 the non-linear effects originate from: -debris or outlying peaks in the data (profile) (labelled 3) ; -deep scratch
40、es or outlying valleys in the data (profile) (labelled 4) ; and - unstable region (curvature) introduced at the plateau to valley transition point based on the combination of two distributions (labelled 5). These exclusions are intended to keep the parameters more stable for repeated measurements of
41、 a given surface. Figure 2 shows a profile with its corresponding mate- rial probability curve and its plateau and valley regions and the parts of the surface that defines the two regions. The profile has a peak that is outlying and the figure shows how it does not influence the parameters. Figure 2
42、 also shows how the bottom parts of the deepest groves, which will vary significantly depending on where the meas- urements are made on a surface, are disregarded when determining the parameters. !-nformation- Is.-atthe-absclssaoftherightside-:i-Ure-offigure2 means_stanbarb . . dm-ationsz UPL LPL UV

45、riteria are designed to ensure that the profile represents a proper two-process surface and that the measuring process is adequate for calculating a stable material probability curve resulting in reliable parameter values. These criteria shall be met in order for the parameters Rpq, Rvq, and Rmq (Pp
46、q, Pvq, and Pmq) to be defined: -The instrument shall be capable of measuring a value of Rq (Pq) from an optical flat that is less than 30 % of the nominal value of Rpq (Ppq), -The vertical resolution of the material probability curve shall be such that at least 40 classes fall within the linear pla
47、teau and linear valley regions respectively. -The digital data density of the material probability curve shall be such that at least 100 profile ordinates fall within the linear plateau and linear valley regions respec- tively. -The ratio Rvq : Rpq (Pvq: Ppq) shall be at least 5. -The conic section
48、regressions result in a hyperbolic solution (see annex A). If the profile does not satisfy the above criteria, a suitable warning message shall give the reason for the failure.
