Abstract: This paper presents the comparison of precision hard cutting and abrasive processes in terms of the surface textures produced and their effects on enhancing functional properties. The main objective of such a comparison is to facilitate the decision whether to possibly replace grinding operations by hard turning with low feed rates. The experimental study performed includes hard turning operations with CBN cutting tools and grinding operations using CBN wheels. For this purpose, the stereometric features of turned and ground surfaces with the Sa roughness parameter of about 0.2 μm were compared. Apart from the set of 3D roughness parameters, the motif, fractal and frequency characteristics were analysed.
