N2 - Surface texturing is a process of applying specific structures onto a surface in order to change its properties or visual appearance. In this paper an advanced machining technology is presented, enabling to machine user defined textures onto the component's surface on conventional CNC milling centres. The technology is based on a piezo- Actuator driven face-milling tool, capable of tool tip displacements with a variable frequency up to 4000 Hz and a maximum amplitude up to 30 μm. The control system of the actuator is linked to the angular spindle position and the translational machine axes, allowing to determine the tool tip position in real- Time and to freely manipulate the control signal according to that information. It is able to perform machining of large-scale and almost seamless texture areas and in the depth range from 2 to 30 μm. The dynamics of the tool enable a fast and controlled depth of cut variation during the cutting process while using process parameters applied in real-life industrial processes. This machining process allows to outperform the widely used laser texturing process by means of material removal rate in the specified process boundaries. The technology is demonstrated by machining of a texture with different geometrical features and will be evaluated on process time and resulting quality.
