Influence of coatings on durability of cutting inserts during longitudinal turning
Balíček, Martin ; Sámelová, Vendula (referee) ; Jaroš, Aleš (advisor)
This thesis deals with the influence of deposited coatings for durability and tool wear during longitudinal turning of steel CSN 41 1600 (E335) and influence of wear and surface quality. The theoretical part is focused on characteristics of turning technology, application, manufacturing and methods of coating cemented carbide and tool wear. The experimental part of the thesis includes the evaluation of the measured values, a description of the material, used tools and machine tool. The values measured in the experiment imply that the most suitable of the tested tool inserts is WNMG 3-1-NF with applied coating TiAlN + TiN. Surface quality decreases with increasing wear of the tool.

High speed steel milling cutters made by powder matallurgy
Svoboda, Martin ; Sámelová, Vendula (referee) ; Jaroš, Aleš (advisor)
Bachelor thesis is a research work describing milling cutters made of high speed steel by powder metallurgy (HSS PM milling cutters). In chapters one, two and three are generally described milling, high speed steels and powder metallurgy. In chapter four are introduced particular HSS PM milling cutters of a few producers. The summary contains mechanical properties of cutters and suitability for machining. It is focused on main type of HSS PM cutters, which are the end mills.

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.

SinuTrain Operate 2.6 tools for programming of CNC machine tools
Švagera, Pavel ; Sámelová, Vendula (referee) ; Polzer, Aleš (advisor)
The master´s thesis demonstrates the SinuTrain Operate 2.6 tools for programming of CNC machine tools. In the first part is done integrating the control system Sinumerik 840D to the most widely used control systems of CNC machine tools and described NC programming methods. The next part of the thesis involves the preparation of technical documentation machined component (front hub on a bicycle) and production design created by using ISCAR company tools. The final part of the thesis is dedicated to creating the NC program and verification of simulation.

Cutting ceramics and its effective use
Heča, Jan ; Sámelová, Vendula (referee) ; Humár, Anton (advisor)
Thesis dealing with cutting ceramics and its efficient use. Introduction describes the general characteristics of the cutting of ceramics, its history and development and production of various kinds. This section describes the mechanical and physical properties with potential application in machining. The se-cond part is an overview of cutting-frame in the range of selected world leaders. Ano-ther section focuses on general assessment of the power of cutting tools and other ma-terials comparison. The fourth part, is comparing the working conditions of producers and tools intended for cutting.

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 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.
