Sinumerik 840D tools for NC programming of machines
Hrabal, Josef ; Sámelová, Vendula (referee) ; Polzer, Aleš (advisor)
This thesis deals with the possibilities of SINUMERIK 840D applications on turning centers. The first part of the thesis is focused on methods of NC programming and especially on the description and operation of the control system through the tutorial SinuTrain 7.5 Ed. 2. The second part of thesis is generated NC programs on the selected components with parametric typing and using a counter. Production technology and the creation of the NC program is created for the CNC machine SP280SY. In conclusion, the thesis is done machining simulation machine with output times.

Parametric programming in Fanuc control system
Hynčica, Vojtěch ; Kalivoda, Milan (referee) ; Polzer, Aleš (advisor)
The diploma thesis is focused on the use of parametric programming family of workpieces. The practical part includes the design of production technology and the creation of a parametric programs for the production of a given group of workpieces using a workpiece measuring probe. The use of common and system variables can be applied to the toolpath programming and the measurement of workpiece offsets, workpieces and machined areas by a workpiece probe and for measuring and checking tools using a tool probe. Measured values can be used in conditional programming to increase the level of automation of the manufacturing process.

Mathematical Model for Faculty Budget
Holá, Lucie ; Roupec, Jan (referee) ; Popela, Pavel (advisor)
The idea of this diploma thesis is an origin application of optimization models to solve a wage funds allocation problem on various institutes of each faculty. This diploma thesis includes an outline of linear programming models, nonlinear programming models, multiply programming models and parametric programming models. Studied questions are debating in wider context of distributing financial resources from the Budget of the Czech republic, through Ministry of education, youth and sports, universities, faculties after as much as various institutes. The accent is given on question of definition assessment scales of achievement criteria with general-purpose kvantification.

The use of parametrical programming for complex part machining
Mohyla, Petr ; Polzer, Aleš (referee) ; Píška, Miroslav (advisor)
This diploma thesis is focused on parametric programming and creation of user cycles in CNC machine tools in control system Sinumerik 840 D sl / 828 D. The first part contains a theoretical introduction to programming and creation of graphical support of the cycle. In the second part there are practical examples with descriptions and explanations that can act as a guide for creation of parametrical programs. These samples are experimentally verified at the end of the work.

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 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.
