A Study on Areal Surface Texture Parameters Based on Grid Type Discrete Surface Topography Data

- 2^nd Report: Feature Parameters and Their Calculation Conditions -

Abstract

Feature parameters of surface texture parameters based on critical points and local geometric features can be utilized to evaluate the subtle relationship between surface function and surface topography data of functional engineering surfaces. This paper describes the parameterizing process of significant surface features derived from the topological theorems for triangulated surface topography data. A reasonable method of determining the threshold value for the significant surface features is presented with prerequisite calculation conditions.
