The manufacturing of metal shim by fineblanking process
Uttendorfská, Magdalena ; Podaný, Kamil (referee) ; Peterková, Eva (advisor)
This master´s thesis is concerning the problem of manufacturing technology of the metal shim, which is a part of automobile brake mechanism. Shim will be made of the S460MC steel and the expected production series is 800 000 pieces per year. This quantity, demanded quality and accuracy of blank are the main reasons for application of fineblanking technology process with pressure edge. The blank will be making by triple–action press produced by Feintool, marked HFAplus4500LT. This press produces two blanks per one action.

Layout solution of a small workmanship within a given company
Urban, Antonín ; Peterková, Eva (referee) ; Štroner, Marek (advisor)
This thesis is focused on the process of making a disposition draft of a small machineshop producing 70000 bearing housings per year. Theoretical part of this thesis is focused on fundamentals of designing machining production units. Practical part describes in detail the process of designing dispositional solution for the machineshop which is based on performed capacity calculations. These calculations were used as a guide in the process of designing two diferent machineshops. The first one is fitted with conventional machining devices whereas the second machineshop uses CNC mills to produce the housing. These two projects are compared to each other to give reader a better picture on which machineshop of the two is better.

Punching technology
Králíček, Václav ; Harant, Martin (referee) ; Peterková, Eva (advisor)
The thesis is focused on punching technology, technology which can create complex-shaped parts from sheet metal. The thesis contains description of the principles of punching, emphasis is put punching tools and various production methods, which can be performed using modern punching machines. Part of this thesis is focused on comparison between punching technology and laser cutting. The comparison is shown on two different semi-finished products made from stainless steel by ACO Industries k.s. These semi-finished products are compared from the point of view of production accuracy and manufacture speed.

Modern methods of tube- and profiles bending
Zouhar, Ondřej ; Žák, Ladislav (referee) ; Peterková, Eva (advisor)
The project elaborated in the framework of Bachelor's study presents a survey of modern methods in the field of bending tubes and profiles. On the basis of literary evidence relating to the bending of tubes and profiles the list was created to summarize all the currently used modern technology in this field. The work covers the theoretical part of the time horizont of the oldest methods of bending to the present methods. In the theoretical part are given the most modern machines used to bend tubes and profiles.

Joining components by forming technologies
Hudeček, Marek ; Šlais, Miroslav (referee) ; Peterková, Eva (advisor)
The project elaborated in frame of bachelor's degree B-STI gives an overview about methods of joining parts primarily made from sheet. Most of these methods are implemented by cold forming technology without machining. In great detail is described joining parts from sheet using technology of seaming in bachelor thesis. Using a new materials in production and requirements on decrease cost require application modern way of joining, some of them are mechanical coupling procedures and joining by deformation strain.

Manufacturing of pressed metal part
Rubáš, Petr ; Peterková, Eva (referee) ; Podaný, Kamil (advisor)
The thesis focuses on the design of the technology of manufacture of metallic insert that is included to the shock absorbing element of truck axle silentblock. The insert is made of ´U´ profile metallic sheets with bent edges at both ends, thickness 2 mm. What was chosen as the most fitting technology based on manufacturing requirements and production series size of 160 000 units per year is conventional tool bending. The required form of the insert is achieved by two operations: in the first step, both metallic sheet edges are preliminary bent and in the second step the central part is bent to the ´U´ form. The material chosen for the manufacture of the insert is micro-alloyed structural steel S 315 MC the mechanical properties of which match requirements of the finished product. The part will be manufactured on eccentric press LEXN 100 C and its production cost is CZK 4.60.

Manufacturing of the steam attemperator protective liner
Kukla, Petr ; Lidmila, Zdeněk (referee) ; Peterková, Eva (advisor)
The Bachelor´s thesis deals with the innovation of the manufacturing of the steam attemperator protective liner. The part will be made of low – alloy steel EN 10216-2 10CrMo9-10. The presented work contains an overview of possible production methods, where the technology of pipe end flaring with a fixed mandrel was chosen as the most suitable. The required material parameters were obtained by the tensile test. The application of the selected technology method was verified by analytical calculations and FEM simulation. According to the determined forming force (810 kN), an electro – hydraulic press OMCN 164 with nominal force 1000 kN was chosen. This machine is fully sufficient for the production of this component. The risk of occurring of a defects was excluded based on calculations and simulation. There was assessed considerable financial saving over 53 % in the technical and economic evaluation. In conclusion, this optimization of production is technically acceptable.
