Abstract
High precision manufacturing processes of technical product surfaces have to fulfil demanding requirements regarding functional characteristics like roughness and gloss. Especially the reproducibility and control of aperiodic surface topographies based on grinding processes are influenced by many manufacturing process factors. This paper outlines a concept for multivariate analysis of measurement data regarding aperiodic surface topographies. The concept is based on non-parametric statistics, due to the particular challenge which is the missing knowledge of the distribution model of the parameters. The application of the worked out measurement strategy and the multivariate non-parametric statistical method is shown within a case study “Cutlery”.
