Sinumerik tools for programming of CNC machines
Kulenda, Martin ; Sámelová, Vendula (referee) ; Polzer, Aleš (advisor)
The master’s thesis incorporates the control system Sinumerik 840D to the most widely used control systems of CNC machine tools. In the first thesis part are analyzed the NC programming methodics, which are relative only to the control system Sinumerik 840D and an essentials necessary to understand the issue in the area of CNC machine tools. Next part of the thesis includes design of the technology and processing of the NC program for machined component (gearbox cover). The NC program is made by ShopMill that is focused on a workshop area. During the program creation is combined a ShopMill and parametric programming, with using of a conditional jump instructions and repetitions. The final part of the thesis includes verification of the selected component production process by simulation and technical-economic evaluation of the designed technology.

Unconventional methods of material cutting
Kulenda, Martin ; Mrňa, Libor (referee) ; Podaný, Kamil (advisor)
The present bachelor thesis summarizes the findings of unconventional methods of materials cutting. The thesis is only concerned with the most common and most appropriate methods used in practice. The described methods include cutting by laser, plasma, water jet, electron beam and ultrasound. For each of these methods, the principle of current technologies and technological equipment used for materials cutting in industrial practice is described. This thesis compares the individual methods in terms of their advantages and disadvantages when cutting different types of materials and also the appropriateness of the use of such methods in small or large series production.
