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.

The Rationalization of Production Part of Injection Pump
Havel, Marian ; Prokop, Jaroslav (referee) ; Osička, Karel (advisor)
This thesis focuses on the rationalization of the production process of plungers and elements of injection pumps in relation to improving the quality of the final products. Today’s technology, which mainly uses single-purpose machines where the production quality markedly depends on the abilities and activities of the operator, will replaced by modern machining centres and CNC machines for grinding all functional parts of the plungers, coupled with modern measuring devices. These production machines with the support of measuring devices will improve the productivity of production and the general quality of the produced components.

Large Turning Centres
Nábělková, Irena ; Jaroš, Zdeněk (referee) ; Blecha, Petr (advisor)
This bachelor's thesis is dedicated to large turning centres. The first part thesis is the summary of large turning centres, their description and types. Usage possibilities of different large turning centres in cutting operations are mentioned too. In the second part, the calculating proposition of a chosen component of large turning centre is solved. This component is spindle-drive. Calculating proposition contains calculation of cutting force, power, total efficiency, utile work and energy.

Analysis of modern milling technologies for shaped parts
Pavelek, Michal ; Kalivoda, Milan (referee) ; Zemčík, Oskar (advisor)
The aim of my bachelor thesis is the analysis of modern milling technologies for shaped parts. The work offers the categorization and definition of shaped parts, and a description of the characteristics of milling techniques and methods used in the production of shaped parts. The work also describes the machines and tools used in the process of milling shaped parts. The last part of the paper offers the evaluation of each analyzed method, their comparing, and points out both their advantages and disadvantages.
