Description of two-process surface topography

Abstract

After two machining processes, a large number of surface topography measurements were made using Talyscan 150 stylus measuring equipment. The measured samples were divided into two groups. The first group contained two-process surfaces of random nature, while the second group used random-deterministic textures of random plateau parts and portions of deterministic valleys. For comparison, one-process surfaces were also analysed. Correlation and regression analysis was used to study the dependencies among surface texture parameters in 2D and 3D systems. As the result of this study, sets of parameters describing multi-process surface topography were obtained for two-process surfaces of random and of random-deterministic types.

Distinguishing the Plateau and Valley Components of Profiles From Various Types of Two-Process Textures

“…It was found that use of the formula (2) assured similar results to those achieved after application of a commercial software. In some cases better results were obtained with application of the new software, compared with the commercial one [26].…”

Statistically representative estimators of multi-scale surface topography: example of aluminum blasted rough samples

“…Some man-made surfaces are obtained as a sequence of surface modification steps, where the first step provides for the coarse finish and the subsequent steps result into the refinement of the surface finish. Such surfaces are often referred to as interrupted finishes or stratified surfaces or multi-process surfaces [33,58]. Although our examined samples were obtained within two fabrication steps, each of which impacted surface topography at different scales, they do not perfectly match the definition of multi-process surfaces as given in [36] since, as will be shown in this paper, the coarse finish was obtained by the surface blasting -the last surface treatment step.…”

Two-Process Random Textures: Measurement, Characterization, Modeling and Tribological Impact: A Review

“…Terry and Brown et al [ 112 ] analyzed ground surfaces, Ham and Powers [ 113 ] surfaces after single-point experimental forming, Reizer et al [ 114 ] textured surfaces and Etxeberria et al [ 115 ] surfaces from biomaterials. Many works on this topic were related to two-process textures [ 45 , 106 , 116 , 117 , 118 , 119 , 120 ]. The following parameters were selected for the description of the cylinder liners of the plateau-honed [ 45 ] and worn cylinder liners [ 116 ]: amplitude parameter, distance between deep valleys, and two parameters that describe the shape of the ordinate distribution, such as Rp/Rt and Rk/Rt.…”

“…Pawlus et al [ 119 ] found after analysis of the modeled profiles that the parameters Rpk, Rk and Rpq parameters, Rvk and Rvq parameters, as well as Mr1, Mr2 and Rmq parameters were intercorrelated. Grabon and Pawlus [ 120 ] added to the parameters Spq, Svq, Smq or to Sk, Svk and Sr2 the following set of parameters: Sz, Ssk, Sal, Str, and mean curvature of the summits [ 121 , 122 ] describing various random two-process textures.…”
