Solution drilling technologies and clamping units
Adam, Jan ; Kubík, Roman (referee) ; Kalivoda, Milan (advisor)
This Bachelor's Thesis introduces drilling technology, construction of clamping for specific component and its examination in terms of technology and economics.First part of Bachelor's Thesis deals with technology of drilling and with instruments for drilling such as drills and reamers. Next is survey of particular types of drilling machines. Second part of this Thesis is about rules for construction of clamping units and their disposal. Analysis of componet for which is clamping unit constructed. Following by construction of drilling gauge,comparing of incidental times with using the gauge and without using the gauge and finally calculation of investment return in to clamping unit.

Cutting of supporting profiles on building
Protivínský, Pavel ; Osička, Karel (referee) ; Kalivoda, Milan (advisor)
The bachelor thesis deals with technology for material cutting on the building site. Firstly, there were described different methods for material cutting, their principle, reached quality of section, demands for requirements on Occupational safety and health (OSH) and there are described different qualification of device operators. Secondly there were described specific condition in a mobile building site. Eventually, there are compared all the examined technologies after the experiment according to different criteria.

Technological design of part "hydraulic cylinder"
Cejpek, Petr ; Slaný, Martin (referee) ; Kalivoda, Milan (advisor)
The subject of this bachelor thesis is the analysis of technological process of manufacturing of the part called hydraulic cylinder in conditions of company S&K TOOLS spol. s r. o. There is an analysis of the present technological process in the beginning of the thesis. The main goal of this task is to find weak spots of manufacturing, create an improvement proposals and realization of practical experiment in concrete conditions of the company. Last part of the thesis is focused on realization of technical and economical evaluation.

Machining of aluminum alloy component
Lačňák, Martin ; Kalivoda, Milan (referee) ; Osička, Karel (advisor)
The thesis focuses on the technology of production of the turbine-type component in Edwards company. It specifically focuses on the part of the turning production, in which in the first part an analysis of the component and the technologicity of its construction is created. Problematic aspects are analysed in terms of material structure and procedure technology. An evaluation of the former and the new supplier is made in terms of rationalization of material structure and their statistical evaluation of rationalization improvement towards keeping to geometrical tolerances. Grooving tools greatly influence the overall machining time during turning. An experiment is made to find out the measured values of the radial forces, the process of chip formation and surface roughness during grooving. The technology of procedure further deals with rationalization of the current machine OKUMA LU25-M and purchase of a new machine Mori Seiki NTX 2000, for which new tool equipment is made in cooperation with Walter company. The final technical-economical evaluation sums up all findings from the research of the given issue. In the discussion, further continuation is suggested for the research in the development and for the continuously controlled component productivity.

New Solutions for Settings Car Headlamps
Glatter, Willi ; Straka, Ivo (referee) ; Kalivoda, Milan (advisor)
The aim is to develop new adjusting element. There were three versions of engineering design suggested, which were consequently simulated for various materials. Optimal material was chosen and came up to production suggested variants. These variants were consequently implemented to the headlamp and were consequently measured and tested. During measuring was under consideration change of CutOff line position after heat imunity and vibration tests. Result is selection only one material and only one engineering design of adjusting element solution, which warrants easy and fast assembly and confidential adjusting of reflector, for standardization and implementation to recently develop headlamps.

Machining technology with the necessity of manual work
Svoboda, Jakub ; Kupčák, Radim (referee) ; Kalivoda, Milan (advisor)
Manual work is still necessary and often irreplaceable. In most cases, it is combined with machine production. As an example of such work we have chosen the production of tin lead alloy organ pipes, which encompasses several machining processes. All aspects of production were analyzed, including specification of the materials used and the various production processes. A pipe was produced according to these specifications for illustration. Individual chapters presented special manual tools and specific machinery. The difficulty and originality of the given production was outlined. This is professional work requiring manual dexterity, logical thought, attention to detail and an artistic spirit. During production we obtained an image showing a part of the cross-section of the pipe perpendicular to its axis. The image shows the correct shape of the soldered joint and the tangential connection of both sides of the sheet. Several aspects of the pipe were evaluated. The final chapters include feedback from customers and a general assessment of this particular work.
