Technology of Production single parts with multiple bend
Daňhel, Marek ; Štroner, Marek (referee) ; Dvořák, Milan (advisor)
DAŇHEL, M. Production Technology for Parts with Multiple Bends. Bachelor thesis, Combined form of bachelor degree programme ENGINERING, subject of study Manufacturing Technology, 1st form, 3rd year of study, academic year 2008/2009, study group 3K1. FME BUT Brno, Institute of Manufacturing Technology, Department of metal forming and plastics. No. of pages 47, pictures 32, tables 6, supplements 9. Bachelor thesis supervisor doc. Ing. Milan Dvořák, CSc. _______________________________________________________________ The project developed within the framework of the bachelor degree programme, subject of study B2307-00 Manufacturing Technology, submits a bending technology proposal for a part with multiple bends. The bachelor thesis presents a theory overview related to the forming operations comprising bending, a selection of suitable alternatives for the manufacture of the given part and the production sequence for this part. The design of the bending tool is made in accordance with valid engineering standards for forming operations. As the basis for production the project includes manufacturing drawings of the punch and lower die and the drawing of the bending tool assembly. Technical and economic evaluation and conclusions in respect of the proposed technology constitute a part of the project.

Production of tool for pressing formed shim into flange
Kolář, Milan ; Císařová, Michaela (referee) ; Dvořák, Milan (advisor)
The Baccalaureate Thesis deals with the design of a tool for fixing of thrust rings in flanges of high pressure fuel injection pumps. The theoretical part of the final project summarizes both theory-based and cold metal and alloy working-based knowledge. Three options of fixing the thrust ring in the flange of a high pressure fuel injection pump have been developed. Based on tests carried out, the option II has been chosen for repairs of fuel injection pumps flanges since it seems to be the most advantageous one. The high pressure fuel injection pump flange is made of AlSilMgMn aluminium alloy. The thrust ring is made by C 75 sheet steel stamping according to DIN 17222 (ČSN 12081). The tool drawing was made on the basis of the best-fit technology repair option. Stamping tools are made of 19 452 steel and hardened to HRC 60-4. The assumed yearly output amounts to 7000 pieces. A special purpose machine is used for repairing fuel injection pump flanges.

The modern processes and technology of sheet metal parts forming
Řáda, Aleš ; Císařová, Michaela (referee) ; Dvořák, Milan (advisor)
This bachelor thesis contains the summary of methods for unconventional sheet metal forming and tube forming, especially in flexible tools. There are some technologies such as rubber pad forming, hydroforming, high-speed forming and hot forming presented. In next part of the work there are three hydroforming methods for tube components described: low-pressure, high-pressure and pressure-sequence hydroforming. Finally there is comparison of these technologies according to several aspects by available web sources.

Forming Technology of Thin Sheets
Musil, Zbyněk ; Žák, Ladislav (referee) ; Dvořák, Milan (advisor)
This bachelor‘s thesis deals with technology of mechanical working of the sheetmetals by cutting for rotary and non-rotary single parts. The first part deal with common dissertation about surface mechanical working, mainly about cutting and meaning of cutting gap in accordance with final cutting. The second part deals with transfer of the new pieces of knowledge from foreign technical literature of surface mechanical working. In the last part there is done an aplication on the particular component.

Production of metal gasket by follow-on blanking die.
Hondl, Jiří ; Dvořák, Milan (referee) ; Forejt, Milan (advisor)
HONDL Jiří: Production of metal gasket by follow-on blanking die. Final term paper elaborated as part of undergraduate studies in Program B 2341 Machine Engineering, presents design of technology for blanket formation of cutouts/parts made of Al-Mg-Si alloy with cold-process die stamping. A study of literature dealing with the process of step-by-step formation and the relevant calculation, it was decided to opt for tool cutting. The cutting tool comprises standardized components consisting of a regular stand that is mounted onto an eccentric tilting press LEN 25 – C with nominal power of 250 kN. The trimming punches and blades are made of tool steel 19 436.8, thermally treated according to drawing documentation.

Makroekonomické šoky v úvěrových a hospodářských cyklech zemí EU
Dvořák, Milan
The theoretical part includes access to economic and credit cycles in the context of economic theories. In the empirical part of the thesis examined the tightness of economic and credit cycles in individual countries of the European Union through the rolling correlations. For implementation of economic policy, it is important to know the direction of the cycles. Causality of cycles in Granger sense is determined by Granger exogeneity.
