Machining of flat-shaped components on CNC machines
Fridrich, Tomáš ; Dvořák, Jaromír (referee) ; Kalivoda, Milan (advisor)
This bachelor thesis deals with machining of flat shaped components using CNC machines. In the theoretical part, the characteristics of CNC machines, NC programming and various methods of workpiece clamping are presented. It is followed by an overview of some Czech and foreign vertical machining centres with traverses only in X, Y and Z axes. Furthermore, an analysis of suitable technological operations for the production of flat-shaped parts is made. The last theoretical chapter deals with flat-shaped components and their division. The practical part of the bachelor thesis is focused on the creation of the NC program and the production procedure of the sample product, the compilation of data into the technological preparation of the production and the evaluation of the production.

Design of rationalization of distribution block production
Kobza, Tomáš ; Zemčík, Oskar (referee) ; Sliwková, Petra (advisor)
This thesis focuses on the proposal of rationalization of the production process of the specified part from the company WT-PRO Czech s.r.o. The introductory part is devoted to the description of the specified part and the analysis of the existing production process, focusing mainly on machining operations. Theoretical part is focused on CAD/CAM systems, machining technologies - milling, drilling and threading, which are essential for the production of the component. It also focuses on tooling materials and chucks. In the practical part, the rationalization of the production process is proposed, which concerns two machining operations. A machining centre is specified for these operations, for which new clamping, new tooling, operating instructions and NC codes have been designed in GibbsCAM. The resulting design is described in the new manufacturing process. Finally, a techno-economic evaluation was carried out.

Design of production technology of a planetary gearbox carrier
Skopalová, Simona ; Dvořáková, Jana (referee) ; Sliwková, Petra (advisor)
The diploma thesis deals with the technological design of the production of the carrier of the planetary gearbox. The thesis describes the used production technologies, which include turning and milling. Furthermore, the thesis is focused on the technological design of the production of a part from a semi-finished product in the form of a bar and forging, the choice of machine and tool equipment and technological-economic evaluation. At the end of the thesis, these variants are compared and evaluated.

Optimal layout proposal of technological workplaces at a small mechanical engineering company
Mohorko, Martin ; Dvořák, Milan (referee) ; Štroner, Marek (advisor)
This master´s thesis is focused on technological designing in a small company ENGITEC Motosport s.r.o. In first theoretical part of the thesis is this subject described in detail and analyzed in terms of economic and technical aspect. Next part describes the current state of the company and the production hall as well with keep on its current layout. In the following chapters is chosen piston-shaped component, which is manufactured by the company and three different variants of the piston production. Then one of them is selected, to which all related capacities calculations are made. In the final part of the thesis is proposed the relevant final layout of the hall and there is also the technical-economic evaluation of the most relevant variant included. Key words

A concept of a revolver hammer manufacturing process
Talanda, Jakub ; Dvořák, Jaromír (referee) ; Sliwková, Petra (advisor)
The objective of this thesis is to propose a manufacturing procedure for the selected part, the Alfa revolver hammer. The paper begins with a short design summary of the part, considers available materials and bar stock, examines individual stages of the manufacturing process and makes a simple economic calculation. It concludes with a series of steps recommended for further action towards full-scale production.

Manufacturing of the Mobile Phone Holder
Hřebíček, Robert ; Žák, Ladislav (referee) ; Peterková, Eva (advisor)
The master´s thesis is focused on the manufacture of mobile phone holder. The semi-finished productis a 1.5 mm thick steel sheetroll of S235JRG1. The annual seriesis set at 200,000 units per year. For the production of the part, the method of shearing and bending in a combined tool was chosen. Both technologies were dissected in a literary study, and a production process was developed to design a tool. A suitable production line was purchased for the entire production and the suitability of production was economicallye valuated.

On the production technology of a specific part
Kalina, Adam ; Slaný, Martin (referee) ; Píška, Miroslav (advisor)
This document describes the design of new production technology specific part in an engineering company. The specific part is manufactured on a machining center by milling method. To create model was used SolidWorks software and to create CNC program was used SolidCAM program. There is production process created with new and old technologies. There is a comparison of both technologies in conclusion.

Solution technology multiple groove guide pulley to circular saw.
Koryčan, Jiří ; Osička, Karel (referee) ; Kalivoda, Milan (advisor)
The project developed within the bachelor's degree by the pulley multiple groove design of the technology for desktop performance circular saws. The design work is finished the production of components for the piece and batch production, the choice of the intermediate processing and description of manufacturing operations, including tools used for the single and series production, production design work for production and evaluation of the proposed variants of the production. This thesis has been developed on the basis of the theoretical knowledge gained while studying at the Faculty of Mechanical Engineering in Brno and personal experiences.
