Abstract

The functional behaviour of manufactured surfaces is influenced by the surface topography. Encouraged by the results obtained in the implementation of two-dimensional motifs for practical profiles, a few attempts have been made to arrive at areal motifs for characterization of the surfaces. In this paper, an approach for establishing three-dimensional motifs based on triangular motif is presented. The triangular motif is formed with three peaks and a deep valley between them. To represent the surface by significant motifs, initial motifs are combined using four rules that are extended from the rules defined in ISO 12085 for combining two-dimensional motifs. Application of this technique to practical surfaces shows interesting results for characterizing the manufactured surfaces.
