Design of production technology for a grinding wheel flange
Němec, Lukáš ; Zemčík, Oskar (referee) ; Sliwková, Petra (advisor)
The bachelor’s thesis deals with the design of technology for the production of a component called a basic flange. The component is used for clamping the grinding wheel and is made of alluminum alloy. First there are theoretically dismantled individual production technologies, machinability and tool materials. The production technology for production in small series is designed and machinery and tooling equipment are selected. Furthermore, the bachelor’s thesis includes technological process and manufacturing instructions, which contains the cutting conditions for each tool. The manufacturing instructions are used to determinate machine time, among other things. Finally, the actual production of the component is shown.

Design of a portable machine for machining large diameter pipes
Boháč, Josef ; Pavlík, Jan (referee) ; Tůma, Jiří (advisor)
This diploma thesis deals with the design of a portable machine for machining large diameter pipes. This thesis is divided into research, calculation, design, and construction parts. The introductory part is devoted to research in the field of joining large diameter pipes, with a focus on flanged and welded joints. Based on the findings from the research part, several construction solutions were considered. In the next part, the most suitable design solution was selected using a multicriteria analysis technique and subsequently elaborated on in detail. The following chapter deals with the calculation of maximal cutting forces and the selection of motor. An air motor was chosen as the most suitable option for the proposed machine. This part is followed by the computational part, which includes strength calculations for the critical parts of the machine. The final part of the thesis is devoted to the construction itself and the description of the individual construction nodes of the machine. The thesis also includes a 3D model, drawings of selected parts, and an assembly drawing.

Production technology for mechanical seal flanges
Stoklasa, Patrik ; Gregor, Lukáš (referee) ; Zemčík, Oskar (advisor)
The bachelor thesis deals with the current technological process of the mechanical seal flange production. It contains an analysis of all tool and material equipment, the process itself and it describes selected cutting conditions and measuring aids. Variant production of technology is also characterized here, where the applied changes are described and explained in order to achieve lower costs from an economic point of view. Both variants are finally compared and evaluated.

Drop forging of flange
Bednář, Jaroslav ; Řiháček, Jan (referee) ; Štroner, Marek (advisor)
The aim of the project developed within the framework of the Bachelor's degree in Institute of Manufacturing Technology is the design of the production of a flange forging by die forging from alloy structural steel 14 220 (1. 7131). Size of production is set on 100 000 pieces per year. Based on calculations, the LMZ 4000 vertical forging press with a forming force of 40 MN is selected for production. Three production operations are selected for a given production. Forging dies are designed using an ejector. The material of the dies is alloy instrumental steel 19 552.8 (1. 2343). At the end of the project, a technical and economic evaluation is carried out where a price comparison and costs for the production of die forging and machining are given.

Improvement of manufacturing technology of flange
Dvořák, Jakub ; Fiala, Zdeněk (referee) ; Jaroš, Aleš (advisor)
This diploma thesis focuses on improvement of the existing technology of the flange part in cooperation with the company Znojemské strojírny, s r.o. The theoretical part describes the technologies used in machining of the component. Subsequently, cutting materials and aluminum alloys are dealt with. A detailed analysis of the existing technology is performed in the practical part of the thesis followed by rationalization of the production process, which was carried out with respect to time and financial savings. A new technological procedure is developed after the improvement of the current production process. Finally, a technical-economic evaluation of the design improvement process is carried out.

Production of wing rib
Ivančo, Radek ; Peterková, Eva (referee) ; Císařová, Michaela (advisor)
The thesis presents a proposal of production of a molded part from the aluminum alloy of group 2024 (dural). Based on the theoretical study and the requirements of the company was designed a cutting tool with a rounded edge for cutting the unfolded shape of the part on the eccentric press LEN 40 C. A new forming tool from textite material for fluid press Quintus QFC was designed. The parts of the cutting tool were designed primarily from normalized (purchased) parts. Manufactured punch and shearing die are made of commonly available tool steels and processed on the attached drawings. The result of the thesis is a recommendation to invest in a specialized workplace for the production of a unfolded shape and reduction of laboriousness adjusting after forming.

Damage tolerance analysis using load interaction models
Vaněk, David ; Augustin, Petr (referee) ; Bvoc, Maroš (advisor)
Master’s thesis deals with study of fatigue crack growth retardation models. This document presents description, evaluation, verification and finally application of retardation models demonstrated on the damage tolerant structure. Analysis was provided on the L 410 NG aircraft in the location of the rear spar lower flange joint. Output of this thesis is comparison of the damage tolerance analysis with the current method using in the Aircraft Industry a. s., i.e. linear model without using load interaction models. The comparisons are fatigue crack growth curves, threshold and intervals of inspection program. AFGROW software was used for verification and application of retardation models.
