A new technology of a machined part
Reňák, Antonín ; Polzer, Aleš (referee) ; Píška, Miroslav (advisor)
The fully fashioned master’s thesis within the frame of the master’s study at the Faculty of mechanical engineering is focused on manufacture problems of complex shaped tool specifically for splitting of wood. In the thesis the concept of construction of the tool is analysed with emphasis on correct and efficient functionality. Large emphasis is laid on the analyse of action of force on the gusset and the analyse of conditions of self-locking. This knowledge is applied to the concept of construction of the tool. In the next part the procedure of manufacture is drafted with specification of suitable tools and machines. Then CNC program is elaborated with using of parametrical programming with mathematical function. Then finally the valuation of theoretical results with real production semiautomatic lathe SPN 12 CNC with operation system Simumerik 810D, SPN 12 CNC.

Sinumerik 840D control system for turning of the shaft for JAWA 23
Motl, Martin ; Sliwková, Petra (referee) ; Polzer, Aleš (advisor)
This Master’s thesis deals with the proposal manufacturing technology of a shaft with gears on a CNC machine tool. The first part of the thesis is focused on the concise description selected shaft and its use. In the next part of the thesis are state selected materials, which are suitable used for shafts and gears. After that is create drawing component, suggest technological procedure, tool list and machine list which are suitable used for manufacturing selected shaft. In the final part of the thesis is create a CNC program for manufacturing the shaft on the turning and milling machine. Program is created in software SinuTrain 4.7 for control system Sinumerik 840D. The CNC program is verified by graphics simulation to determine a correct function

Contactless measurement of surface temperatures during turning
Merenda, Jiří ; Slaný, Martin (referee) ; Polzer, Aleš (advisor)
The goal of this thesis is the incorporation of the contactless measurement of surface temperature among other methods of temperature measurement. Technical preparation for experimental measuring on the machine-tool. Comparison of influence of cutting conditions on the development of surface temperature of workpiece during the machining process with usage of the camera ThermaCAM CS2000. The economical analysis of the contactless measurement of surface temperature is determined in the last part of this thesis.

Application of the CAD/CAM software and Sinumerik control system in machining
Láznička, David ; Kalivoda, Milan (referee) ; Polzer, Aleš (advisor)
This Master´s thesis is focused on the design of a shaft component and its production using CAD/CAM software and the Sinumerik control system. The first part is devoted to the analysis of current possibilities in NC programming. In the next part, the actual design of the rotating part and the elaboration of the necessary technical documentation is performed. The last part is the verification of the developed NC program using graphical simulation and justification of the chosen solution.

Sinumerik 840D tools for programming of nutcrackers
Kundela, Miroslav ; Kubík, Roman (referee) ; Polzer, Aleš (advisor)
This thesis is engaged chip machining using the system Sinumerik 840D-ShopTurn. The first part of the thesis is engaged the incorporation of the control system Sinumerik 840D - ShopTurn among other control systems. The thesis also deals with the basic methods of NC programming with an emphasis on workshop-oriented programming. The practical part includes design and preparation of technical documentation for the selected part (nutcracker), including creating a CNC program using workshoporiented environment - Sinumerik 840D ShopTurn. The program was validated using a graphical simulation software SinuTrain 7.5 and also directly at the machine SP 280SY. At the conclusion was created techno - economic evaluation of the proposed technology.
