Wire electrical discharge machining
Gvizd, Michal ; Mouralová, Kateřina (referee) ; Osička, Karel (advisor)
Bachelor thesis elaborated during the bachelor study discusses the electrical discharge cutting of materials with a wire electrode and its usage in industry. The thesis is divided into two fundamental parts –the theoretical and the experimental one. The theoretical part describes the historical development, explains the basic principle and fundamentals of this unconventional way of machining with the definition of methods using this technology. The thesis is focused on the electrical discharge machining, thus gougers are mentioned only peripherally. Afterwards, the wire electrodes used, main machine parts, cutting conditions and advantages of this technology are analyzed in detail. The experimental part deals with the evaluation of cutting surfaces of the sample components with respect to dimension accuracy, surface quality and describes factors which affect these characteristics. The emphasis is put on the machining of the tool steel. Conclusion discusses the analysis of the assembled measurements, their technological/economical analysis and outlines the direction of development in the possibilities of this unconventional technology of material separation.

Production of flanges using the procedure PPAP , and ISO 9001
Prokeš, Tomáš ; Zahradníček, Radim (referee) ; Mouralová, Kateřina (advisor)
In the first part of this thesis is described implementation of quality management system in a small company according to ISO 9001. Next part is about production process by method PPAP. In this section is solved primarily ISO 9001 standard, statistical control of production and certification company according to requirements of ISO 9001. Second part is focused on mass production of flange by using the company facilities Kovobrábění Sobotka. In the end of thesis are reflected weaknesses of production. In the conclusion is described technical and economic evaluation of implementation QMS and machining sample parts.

Manufacturing of Components for Sewing Machine
Paděra, Radek ; Mouralová, Kateřina (referee) ; Kalivoda, Milan (advisor)
This bachelor's thesis aims to produce one specific part of the sewing machine - the carrier. First chapter contains analysis of all parts of the sewing machine including the function part. There is also mentioned existing manufacture process with the description and all neccessary tools to produce these parts. Another part is focused on design of the new manufacture process that includes CNC machines with option to create semi-product, material calculations, technological process and calculations of all machine times of each tools. The last part of this thesis aims on assessment of designed manufacture from the technical and economical view.

Drilling technology solution in the maintenance center of small firms
Huňáček, František ; Mouralová, Kateřina (referee) ; Kalivoda, Milan (advisor)
The basic characteristics of the drilling technology, view of tools for drilling, descriptions of the parts and angles of twist drill are described in the first part of this project. In the second part of this project there are descriptions of various drilling technologies, the choice of cutting conditions and the choice of cooling and lubricating emulsions and oils. The range of tools, machinery and clamping equipment in the workshop machinery maintenance sugar factory in České Meziříčí are described in the next part of the project. Also specific technological conditions for the production of precision holes (with a use of a calculator) was determinated. After that their production was performed. In the end the possibilities of production machinery maintenance workshops during production of holes using drilling tools are shortly valorized.

Technology of wire electrical discharge machining
Galko, Adam ; Mouralová, Kateřina (referee) ; Osička, Karel (advisor)
This thesis talk about practical application of wire electrical discharge machining (WEDM), which belongs to electro-erosion machining methods. This thesis is focused on the production of cutting dies produced by company FOR MIX s.r.o. Trenčín. We can consider the cutting die as a typical product of company´s product program. In the practical part of this diploma thesis, there is detail of technological aspects and operating costs for wire electrical discharge machining technology in specific condition of company FOR MIX s.r.o.

Solution technology of manufacturing for part "disc of coupler"
Borek, Vít ; Osička, Karel (referee) ; Mouralová, Kateřina (advisor)
An introduction to main principles of coupling and description of basic types has been done. An analysis of the given component and a proposal for suitable intermediate was made. A selection of machines and tools for individual operations has been done. A proposition of technologic process and enumeration of machines times was proposed. Economic evaluation containing costs for tools, cooperation, workmen’s wages, intermediate and energy for operating machines has been calculated.
