How to select the most relevant 3D roughness parameters of a surface

Abstract

This is the pre-peer reviewed version of the following article: Deltombe R., Kubiak K.J., Bigerelle M, How to select the most relevant 3D roughness parameters of a surface (2011) Summary:In order to conduct a comprehensive roughness analysis, around sixty 3D roughness parameters are created to describe most of the surface morphology with regard to specific functions, properties or applications. In this paper, a multiscale surface topography decomposition method is proposed with application to stainless steel (AISI 304), which is processed by rolling at different fabrication stages and by electrical discharge tool machining. Fifty-six 3Droughness parameters defined in ISO, EUR, and ASME standards are calculated for the measured surfaces. Then, expert software "MesRug" is employed to perform statistical analysis on acquired data in order to find the most relevant parameters characterizing the effect of both processes (rolling and machining), and to determine the most appropriate scale of analysis. For the rolling process: The parameter Vmc (the Core Material Volume-defined as volume of material comprising the texture between heights corresponding to the material ratio values of p = 10% and q = 80%) computed at the scale of 3 mm is the most relevant parameter to characterize the cold rolling process. For the EDM Process, the best roughness parameter is SPD that represents the number of peaks per unit area after segmentation of a surface into motifs computed at the scale of 8 µm.

Non-destructive and semi-destructive diagnostics of concrete structures in assessment of their durability

Using such methods one can obtain a 3D image of the surface of concrete [6][7][8][9][10]. Analysing the image by means of dedicated computer programs one can generate, e.g., the values of 3D roughness parameters in accordance with ISO 25178 [11].…”

“…They analyse the kinematics of the work of Rules for describing surface parameters after cutting can be found in the ISO 4287 and ISO 25178-2 norms [8,9]. In their work, Deltombe et al [10] analysed 3D surface morphology and the influence of numerical methods of data analysis on resultant roughness values. The values were evaluated considering the socalled 'scale size effect', as described by Van Gorp et al in their article [11].…”

Surface characterization of die inserts used for LED lamp plastic lenses

“…In their study, various texture parameters, adopted, or not, by ISO standards and their distinctive impacts were considered. In 2013, Deltombe et al [24] proposed a multiscale surface topography decomposition method as a new methodology to select, without preconceived opinions, the 3D roughness parameters relevant for discriminating different topographies. The material used in the above study was rolled stainless steel and was machined using an electrical discharge tool.…”
