The microstructuring of component surfaces is a method to optimize the adhesion of cells in biological systems. Ultra-precision cutting represents a technology to manufacture microstructured surfaces. When compared to conventional cutting processes additional effects influencing the material surface have to be considered, such as the size effect between the cutting edge of the tool and the depth of cut or the inhomogeneous structure with anisotropic properties. The aim of the presented research is to investigate the surface integrity in ultra-precision cutting of cp-titanium in the micro- and nanoscale. Quick-stop tests were conducted in orthogonal cutting using an ultra-precision turning lathe in order to understand the chip formation process. These investigations of the chip formation process allow to understand the resulting surface integrity. The analysis of the surface integrity concentrated on the burr formation and the surface topography.
