Paper deals with the machining of super-hard ceramics by turning. The introductory part deals with analysis of used ceramic materials and their use in technical practice. Since it is a very hard technical ceramics and particularly resistant material, at present, is increasingly used to produce components that ensure long life and particularly high resistance, even in aggressive environments where metal materials can no longer be used. Products from ceramics are pressed and sintered directly to the desired shape, but in some cases they have to be machined, which technically can cause a problem. The aim of the experimental part is selection of suitable cutting insert, determining of cutting conditions that would ensure the productive machining of given ceramics. Work may serves as a troubleshooting support for machining ceramics.

Objectives of the paper are intended to implement system solutions to nondestructive evaluation of technologies associated with verification of equipment, preparation of samples with different types of functional properties and their subsequent evaluation of various scientific methods. The main objective of experiments is to transform new knowledge of non-destructive technologies into industrial practice in the evaluation of functional properties of the surface and subsurface layers of these technologies. The aim is to increase the level of cooperation R & D institutions with social and economic practices through knowledge and technology transfer, and thus contribute to increased economic growth of the regions in Slovakia. This work is related to the project with the University of Zilina OPVaV-2009/2.2/04-SORO number (26220220101). Its name is Intelligent System for Nondestructive Technologies to evaluation of functional properties of parts of X-ray-diffractometry. The main objective of the project is to transform new nondestructive technology for knowledge transfer to industry for evaluation of functional parts in surface and subsurface layers of non-destructive techniques.
