Turned multifunctional surfaces are a new typology of textured surfaces presenting a flat plateau region and deterministically distributed lubricant reservoirs.Existing standards are not suitable for the characterization of such surfaces, providing at times values without physical meaning.A new method based on the separation between the plateau and valley regions has been developed.After properly determining a threshold between plateaus and valleys, the two regions are divided in two distinct profiles, which can be studied separately according to the specific function.
