VARIATION OF AREAL PARAMETERS ON MACHINED SURFACES

Abstract

This paper presents study of variation of areal parameters on machined surfaces. These surfaces were measured using stylus equipment. After form removal, parameters from ISO 25178 standard were computed using TalyMap Gold software. Then these textures were divided into the smaller sub-areas, for which the parameters were calculated again. Relative deviations between parameters from measured areas and sub-areas were computed as well as the coefficients of variation of parameters, being the ratios of standard deviations to mean parameter values.
