Design of production technology for a distribution block
Večeřa, Jiří ; Píška, Miroslav (referee) ; Sliwková, Petra (advisor)
The master's thesis focuses on the design of manufacturing technology for a selected component made of ductile iron EN-GJS-400-15. The theoretical part of the thesis discusses the technologies used in component manufacturing, such as turning, milling, drilling, surface grinding, honing, thermal energy debburing and phosphating. The subsequent sections specify the specific production machines and cutting tools utilized in the component manufacturing process. In the practical part, a technological procedure is proposed, describing the sequence of manufacturing operations required for producing the component. It also includes inspection operations for measuring tolerances. Additionally, manufacturing instructions are provided, offering a detailed description of individual manufacturing operations and specifying the frequency of tolerance checks. The thesis concludes with a technical-economic evaluation, summarizing the material costs for production preparation, the costs for ensuring the production itself, and evaluating the manufacturing technology.

Mechanical properties of Nodular Cast Iron prepared by method Tundish and process Initek
Vítek, Radovan ; Hotový, Ivan (referee) ; Věchet, Stanislav (advisor)
This bachelor thesis deals with a properties and production of nodular cast iron. The first section describes the classification, distribution and structure of nodular cast iron. The second part is focuses on the description of nodular cast iron, modification, inoculation and production. A strong effort is made on the production of nodular cast iron using the Tundish Cover method and the Initek process. In conclusion, the structure of the material is evaluated on samples that were delivered for metallographic analysis. The final evaluation of the structure of the material is used to compare the mechanical properties of a nodular cast iron produced by Tundish Cover method and Initek process.

Solution technology of part "víko" in the condition of a middle-sized company
Kavan, Petr ; Prokop, Jaroslav (referee) ; Kalivoda, Milan (advisor)
The diploma thesis is concerned with evaluation of actual production technology of part “hydraulics cover” and with design of new, progressive variation machining of this part. Solution is focused at first on rationalization of cutting tools and choice of suitable cutting tools. An effort is to achieve shorter production time and decrease costs on production of component. With this problem is related alteration of technological documentation and technical economic evaluation for determination return rate of investments into progressive cutting tools.

Influence of cement moulds on the structure of nodular iron castings
Stachovec, Ivo ; Šenberger, Jaroslav (referee) ; Rusín, Karel (advisor)
The object of the diploma thesis was to solve and to describe the influence of cement sands moulds on the structure of castings with cast iron LKG. The work was intent on watching the tendency of cement sands to the metal penetration of castings, rising of the compounds on the metal mould interface and liquid metal and accompanies elements on the shape of the graphite in the surface of casting. The study of this processes has a big theoretical and a practical meaning, for prevent and prediction of rising of the defects that are attached with unsuitable choice of sand.
