This paper focuses on the development of high temperatures in the cutting zone during high performance grinding. In order to identify the infl uence of grinding temperature on surface integrity, temperatures were measured in the workpiece surface layer under diff erent machining conditions. Beside this, under the same conditions, the surface layer(More)
The spread of the open innovation model created new challenges for further implications of the Web in making the innovation happen. In this paper we present a research on the application of the Web technologies in the open innovation model. We analyze technologies for expert search, key words matching and social propagation that would enable more efficient(More)
In this paper, we present the results of a study of TiN thin fi lms which are deposited by a Physical Vapour Deposition (PVD) and Ion Beam Assisted Deposition (IBAD). In the present investigation the subsequent ion implantation was provided with N2+ ions. The ion implantation was applied to enhance the mechanical properties of surface. The thin fi lm(More)
