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.

Sinumerik 840D tools for programming of CNC machines
Olina, Anna ; Sámelová, Vendula (referee) ; Polzer, Aleš (advisor)
Master’s thesis presents the history and the present-day state of CNC machines and their control systems. This thesis describes both the basics and the advanced methods of programming which can provide the ability to create NC program for Sinumerik 840D to operate. The second part of the thesis deals with the development of the technology to machine the part (the frame of the reduction gear) and corresponding NC program. This program is created by means of the work-step programming (ShopMill). The final verification of the program was provided by means of simulation component of the control system.

Sinumerik tools for programming of CNC machine tool
Chytil, Tomáš ; Sámelová, Vendula (referee) ; Polzer, Aleš (advisor)
The bachelor thesis focuses on the usage of possible ways of the Sinumerik system for programming of the form of the drop forging. The first part of the thesis contains of the characteristics of the part and its function in the composition. In the second part there is all the proper visual documentation. The following parts of this piece of work is devoted to the history and specification of the Sinumerik control system and a suggestion on how to make a forging die.The next part is contributed to the possible ways of how to produce a form in the Sinumerik system. The final part deals with the very formation of the programme and its graphic simulation.

Prototype Part Design Using the Reverse Engineering Technology and Rapid Prototyping
Luňák, Václav ; Sámelová, Vendula (referee) ; Slaný, Martin (advisor)
This Bachelor thesis is dealing with the manufacturing process of a motorcycle turn signal part using the technologies of reverse engineering and rapid prototyping. The thesis contains a brief description of the available technological methods. The following chapters deal with designing the component and its preparation for casting. The component is manufactured using the FDM method. The quality check is performed by the ATOS 3D scanner, which compares the newly manufactured component to the original part. The next step is the preparation of a silicone mold, which is used to cast more parts. Finally, the cost-effectiveness of this method is compared to the method using metal molds.

Design of a measuring equipment for distance sensors calibration
Zindler, Lukáš ; Sámelová, Vendula (referee) ; Štěpánek, Vojtěch (advisor)
This study aimed deals with the design of a calibration equipment for an inductive distance sensor. The theoretical part provides a basic overview of metrology and the state of knowledge in the field of sensors. In the practical part, several concepts of measuring equipment are suggested, a suitable calibration equipment is selected and assembled, and at last the compensation of the systematic error of the sensor is performed.
