Abstract

The multifunctional surfaces herein studied are intended for carrying high loads as well as providing lubrication. They are produced by hard turning, creating a periodic pattern that will constitute the lubricant channels, followed by accurate Robot Assisted Polishing to smooth the tops of the cusps to obtain a well defined bearing area. It is studied how the surface topography varies with the number of polishing passes. Hard-turned specimens with different feed rates are polished changing stone, spindle speed and pulse frequency. The profiles are filtered with the robust Gaussian regression filters according to ISO 16610-31 and analyzed according to ISO 13565. It is depicted how existing standards are not sufficient to fully characterize this kind of surfaces.
