A special issue of International Journal of Surface Science and Engineering
Surface topography is a foremost characteristic among the surface integrity magnitudes and properties imparted by the tools used in the various manufacturing processes and especially their finishing versions.
Over the years, the characterisation and evaluation of engineering surface texture has constituted a challenging metrological problem, attributed largely to the usually complicated form of the generated surface profiles and the need to obtain a satisfying description globally as well as at various levels. Furthermore, emerging technological advances put new limits in manufacturing tolerances, while a better understanding of tribological phenomena implies the need for functional surface characterisation. This 'dualism' of process and function is encountered in the evolution of surface metrology, which in turn caused a plethora of texture parameters, referred to by D. J. Whitehouse as a 'parameter rash'.
The ISO standards 4287:1997, 12085:1996 and 13565-2:1996 have adopted the central- line system, motif combination and Abbott curve characterisation, respectively. A vast amount of research work towards a concise and proper characterisation of surface texture is found in literature, with an inevitable emphasis on the association of profile characteristics with the manufacturing process parameters.
The application of multi-parameter analysis or the introduction of new parameters for process control and functional application in surface metrology, as well as the introduction of novel techniques for surface texture characterisation and evaluation, is the scope of this special issue. In this regard, a collection of various examples, from industrial inspection to functional correlation, using contemporary techniques of surface texture analysis, will be presented.
