A new technology of a machined part
Záveský, Zbyněk ; Kolář, Ladislav (referee) ; Píška, Miroslav (advisor)
This master’s thesis is focused on CNC machines. It deals with the characteristics, description, coordinates, advantages and disadvantages of the CNC machines and utilization of the CAD/CAM software. The next part of this thesis deals with the suggestion for choosing the best technology for milling slots. Milling strategy, cutting processes and cutting conditions are described in this part as well as all the issues concerning the manufacturing of the milling slots.

Analysis of the minute cost rate for CNC machines
Kubiš, Richard ; Humár, Anton (referee) ; Píška, Miroslav (advisor)
This master’s thesis is focused on analysis of the minute cost rate for CNC machines. It describes cost inputs and a way of including them in the minute cost rate. Further describes creating of mathematical model, minute rates for entire CNC machine and possibilities of using of the minute rate for optimalisation. It points out that no general calculation method is existing and that there are problems with creating certain minute rate and need of individal approach.

Controlling CNC machine tools with focus on three-axis milling - triaxial milling machine EMCO and its control systems
TETOUR, Milan
The first section of this thesis describes the problem of programming computer numerical control (CNC) machines and the way how they are currently used in industry. The next section compares current control systems of the CNC machines, the general principles of programming with the possibility of using workroom oriented milling. Then the EMCO machine is described, its operation, setup, practical advices and also examples of the Sinumerik 840D control system by Siemens. The final section introduces a practical demonstration of machining by using the NC program for milling a representative component on the machine metioned above.

Progress in technologies of wood processing
ŠIMEK, Jaroslav
In this thesis I present an overview of the development of wood processing. The first part is focused on the wood as a material and furthermore on hand tools for woodworking. The practical part deals with history and present of material processing on CNC machines. The whole work is supplemented with photographs of the operation. The thesis is also focused on the possibilities and advantages of the introduction of new technologies in wood processing companies. The thesis is complemented with authentic DVD recording to illustrate the new technology. The work can be used to enrich students´ideas about the new technology of wood processing.
