Abstract The standard ISO 13565-2 defines the RkRk parameters for the functional characterisation of technical surfaces. So far, no particular material measures for the calibration of these parameters have been defined in the international standardization. For the application and the functional behaviour of technical surfaces the RkRk parameters however have a critical significance, so there is a demand by…

Abstract. With the development of science and technology, the higher and higher surface accuracy ofworkpiece is required. The characterization of surface topography affect greatly on functionalperformance of workpiece. In recent years, many researchers have made a large progress on the studyof surface topography and presented some related standards. The assessment of parameters of surfaceroughness, however,…

Abstract This paper concerns practical realization of open surface profile filtering and roughness evaluation. The profile is represented in the form of discrete data. A code for applying discrete Gaussian filter to a surface profile in accordance with ISO 16610–21 is presented. Linear interpolation before numerical integration for average roughness calculation is proposed. A method…

Abstract: Characterization of surface topography, roughly divided into measurement and dataanalysis, can be valuable in the process of validation of the tribological performance of machinedparts. Surface topography, especially the roughness, can respond straightly to the machining processand, in some cases, is defined as a fingerprint of the manufacturing. When considering the highprecision of surface topography…

AbstractIn this paper, the general model of the Gaussian regression filter for areal surface analysis isexplored. The intrinsic relationships between the linear Gaussian filter and the robust filter areaddressed. A general mathematical solution for this model is presented. Based on thistechnique, a fast algorithm is created. Both simulated and practical engineering data(stochastic and structured) have…

Abstract The height and spacing characteristics of the surface profile influence the functional behaviour of the manufactured part. A new method known as motif combination has been recommended in French standards to obtain the height and spacing characteristics of the surface profiles. An attempt has been made in this paper to compare motif combination techniques…

Abstract The E-system of roughness measurement can be used either for a two-dimensional or a three-dimensional assessment of surface roughness. The procedure for computing the two- and three-dimensional envelopes from digitized profiles is briefly explained. This method will be useful for verifying the results obtained by practical instruments. The filtering characteristic of the E-system, when…
