Cermets and theirs effective use
Vaněček, Stanislav ; Sedlák, Josef (referee) ; Humár, Anton (advisor)
The Thesis described within the scope of the Master Program is focused on cermets, which belong among cutting materials. The introductory portion of the Thesis presents the characteristics of cermets from the perspective of production, physical-mechanical characteristics, marking and usage in cutting. The core portion of the Thesis focuses on the role of cermets in the category of leading world producers of tools and instrumental materials, cutting evaluation, and the suggested working conditions of cermets in lathing operations. The working conditions are prepared for steel and cast iron. The conclusion of the Thesis focuses on a technical-economical analysis of cermets.

Využití akustické emise při hodnocení procesu obrábění
Dostál, Jiří
The thesis deals with the application of acoustic emission system to the machining process. The thesis describes the gist of the machining, the influence of the cutting conditions on the machining process, and attention is also focused to the used tooling materials and creation of sliver. Another part deals with acoustic emission, its basic characteristics and areas of its use. In the experimental part, is determine the measurement objective, is described there methodology of the measurement and the data obtained from the measurement is then evaluated.

Moderní trendy v technologii kovoobrábění
Dostál, Jiří
This bachelor thesis deals with the issue of metal cutting and automation of manu-facturing processes. The first part is a presentation of some of the theories and methods of cutting and non-cutting operations. The basis and principles are described. Following part focuses on cutting materials, its basic division and expected progress. Next part describes distribution of machining centres and the market presence. The attention is also focused on robotization and its use in engineering industry. The most perspective and modern technology appears to be the non-cutting operation, which is described in this thesis.
