The main objective of the comparison of precision hard cutting and abrasive processes in terms of the surface texture is to facilitate the decision whether to possibly replace grinding operations by hard turning with low feed rates. In this study, hard turning operations with Cubic Boron Nitride (CBN) cutting tools and grinding operations using electrocorundum Al2O3 and CBN wheels were performed in order to generate surfaces with the Sa roughness parameter of about 0.2 μm. 3D roughness parameters and the frequency, fractal and motif characteristics were analyzed.
