Abstract

In this review we will address many of the problems that are encountered when designing and carrying out comparisons of surface texture measuring instruments. Previous comparisons are presented to highlight some of the key issues. The limitations of stylus and optical instruments are discussed with a focus on the spatial bandwidths in which they operate. Advice is given on how to design comparisons to avoid variations in the results that are due to the operating principles and bandwidth limitations of the instruments involved. Methods for matching the bandwidths of different instruments are presented and some examples are given that highlight problems. The software aspects of instrument comparisons are also discussed. Finally, some advice is given on how to compare profile and areal surface texture measurements.
