Design of clamping device for mass production on CNC milling machine
Blahuta, Jiří ; Foltýn, Jan (referee) ; Svoboda, Petr (advisor)
This bachelor thesis deals with a design of a milling fixture and a fixture for broaching on a press. The fixtures enable progressive production on a CNC machine with a high efficiency and minimal downtime. The fixtures are designed for a serial production of a specific component in automotive industry with quantity of 250 000 units per year. The main goal and partial goals of the thesis were accomplished. The designed milling fixture uses wedge clamps and hydraulic cylinders for clamping. The broaching fixture uses springs to position the workpiece. The design of proposed fixtures was verified by production capacity calculations, which prove that the series will be produced in a required time. To further increase productivity, it was suggested based on calculations to use five milling fixtures in the milling machine. The design of the broaching fixture was verified by FEM simulation, which showed that the device is sufficiently rigid and strong. The result of the work is a design of two fixtures in the form of 3D models and drawings. The work includes, among other things, research of three-axis CNC milling machines, broaching machines, and wrought aluminium alloys.

Analysis of causes of inaccurate production
Foral, Jakub ; Trčka, Tomáš (referee) ; Kalivoda, Milan (advisor)
The topic of the Master‘s thesis focuses on NOK pieces which are produced during the production of components. NOK pieces and their rework significantly increase the company‘s costs. In the individual chapters there is an analysis of the company and the definition of a critical point. The FPY indicator was used for the analysis of the company, from which the component was identified. Three improvement concepts have been created for this component. These concepts may reduce the rate of NOK products in the company. The conclusion of the Master‘s thesis presents the evaluation and implementation of the selected change.

The Production of the Components on the Press Brake Machine
Zahradníček, Lukáš ; Řiháček, Jan (referee) ; Peterková, Eva (advisor)
The project elaborated overview of the production technology of the components on the press brake machines. It is based on study of theoretical pricniples in literature and modern practical instances as added value. It discussed about bending technology in general, about its priciple and parameters. Then there is overview of most used methods of bending at press brake. bending tools, its process of production and tool clamping. The main emphasis is placed on press brake machines. There are discussed the main types of machines, structure of machine and last but not least there are presented selected world manufaturers of press brake machines. For a better idea there is showed production of particular component in manufacturing plant in the end. Acquisition of the project is in simple description of press bending technology and way of work on press brake machines. The useful trasfer may be for example to education.

A design of pneumatic stationary chuck
Hurtík, Daniel ; Pavlík, Jan (referee) ; Tůma, Jiří (advisor)
This Bachelor’s thesis is focused on the construction of a pneumatic stationary chuck, but it also mentions something in the field of workpiece clamping and machine vices for rotating workpieces. The first part contains a brief search in the field of clamping, which focuses mainly on the clamping of rotating parts. The next chapter focuses on possible solutions that would meet our requirements. The main components of the chuck are then calculated and designed so that subsequent construction can be performed in any CAD software, which is the content of the next chapter. Finally, some requirements for chuck operation are summarized.

Clamping mode of tools and workpieces
Kamenická, Pavlína ; Pekárková, Eva (referee) ; Kalivoda, Milan (advisor)
This bachelor's thesis deals with a clamping of machine tools and workpieces in an engineering practice. It provides an overview of the possibilities of their clamping during machining. The individual ways of the clamping for specific machining operations are there presented sequentially and also their functional principles are described in detail. In the thesis is contained also a practical analysis acquired in a business environment. Its aim was to find out the real use of the clamping of machine tools and workpieces in practice. In the conclusion are added examples of typical clamping devices from catalogue sheets of various companies.
