Abstract

Achieving consistent surface texture measurements is of vital importance to the performance of many components in well-established fields such as mechanical engineering and manufacturing, and is becoming increasingly important in the emerging field of nanotechnology. The route to traceability in surface texture measurements is still ill-defined and it is very uncommon to find a measured surface texture parameter presented with its associated uncertainty. This report summarises the methods used to calibrate surface texture measuring instruments and discusses the various ISO standards in the field. An uncertainty analysis of a fully traceable two-dimensional surface texture measuring instrument: NanoSurf IV, is undertaken and the uncertainties in measured surface texture parameters are analysed.
