Propagation of measurement uncertainty for surface texture parameters

Abstract

This paper outlines a proposal for research into fulfilling the need for reliable software algorithms to compute the standard uncertainty of surface texture parameters. The target will be to develop a library of software algorithms for the sole purpose of safely calculating surface parameters from ISO standards. The research pays particular attention to the propagation of measurement uncertainty through each parameter, something which has not been thoroughly addressed in this field. By taking existing methodologies to express the uncertainty of measurement the endeavour is to tailor a new method that will specifically address the special issues concerned with determining surface texture parameters from nano-scale surfaces
