Abstract

Stylus profilometry has been used for many years to measure surface finish. A stylus is drawn across a surface creating an x-y data set. A range of two- dimensional surface parameters can be calculated. Measurements are now possible using 3D by raster scanning a stylus across a surface. This creates an x- y-z data set. Although various 3D parameters can be calculated, there is currently no 3D standard for parameters whereas there are 2D standards. Many studies of two dimensional parameters, their usefulness and reliability have been published but as yet there has been little work done on three dimensional parameters. This project seeks to redress the balance by presenting the results of a study int
