Abstract

The characterisation of surface topography is critically important in many disciplines and industrial applications including tribology. Surfaces are often characterised through the use of parameters which attempt to provide an indication of some attribute of the surface such as amplitude variation. This paper addresses inherent properties of two-dimensional parameter variation for the case of two orthogonal directions for some typical machined surfaces. Some experimental results illustrate that parameter variation is determinate rather than random in some cases, and that the variation is unaffected by measurement and signal-processing conditions. The factors which produce determinate and significant parameter variation are determined, by the analysis of surface topography features. The sensitivity of parameter variation to changes in surface topography is also discussed.
