Positioning of the tilting head of a milling multi-purpose machining center with a horizontal spindle axis
Grepl, Martin ; Marek, Tomáš (referee) ; Marek, Jiří (advisor)
The thesis deals with the positioning of the tilting head of the multifunctional milling centre in three axis. The aim of the thesis is to design a multifunctional milling machine centre with a horizontal axis of the spindle in cooperation with Bc. Ľubomír Vazovan, Bc. Ján Rapčan a Bc. Tomáš Hynšt, who are working on the issues of the headstock, automatic tool change and palletization. The thesis also contains proposals of certain options and their subsequent evaluation by the multicriterial method PATTERN. The resulting construction is complemented by calculations of the main construction nodes.

Boilers for house heating
Grepl, Martin ; Štelcl, Otakar (referee) ; Baláš, Marek (advisor)
This bachelor thesis deals with the issue of small boilers for solid, liquid and gas fuels for heating houses. Its introductory part describes types of fuels, their basic classification, characteristics, and environmental impact during combustion. Various types of boilers suitable for domestic heating are described in its second part. It shows classification according to the type of combustion fuel, advantages/ disadvantages, and also basic parameters of these boilers. The last part of this thesis focuses on calculation of selected boilers in terms of their parameters and cost.

Revision of steam turbines and repair design
Grepl, Martin ; Trněný, Bohumil (referee) ; Fiedler, Jan (advisor)
The theme of this master thesis is the revision and repair design of the condensing steam turbine SST 600 in Bielsko-Biala. The thesis deals with the revision of the steam turbine and the repair design of the damaged parts, the overall analysis of the separation of the steam of the split plane and the calculation of the parameters for tightening the new screws. The master thesis is given for a specific case. The introductory part of the master thesis deals with a basic description of the repaired steam turbine. Subsequently, a review of individual disassembled parts is given and the scope of the repairs is stated. In the next part of this thesis are summarized the causes of the steam leakage of the dividing plane at the points of the cross section and in the area of the control stage. The last part deals with the sealing problem of the split plane and the related main part of the master thesis is the calculation of the tightening parameters of bolts in the turbine housing. Another aim of the master thesis is to create drawings of the lightening of the split plane on turbine house.

Component measurement with a FARO device
Grepl, Martin ; Mouralová, Kateřina (referee) ; Kalivoda, Milan (advisor)
This theses deals with the measuring of comparts from the lastest technology FARO. It introduces technology FARO and the most significant products among the measuring arms. Subsequently, all the features of the measured particles, that are necessary to know for the whole process, are mentioned. The whole process of measurement is described step by step in the practical part. The aim of the measurement is to verify the dimensions which are prescribed by the author and geometrical tolerance of the particles via measuring arm. The thesis also consists of a final protocol of the measuring process, created by the program PolyWorks. Finally, the particle is considered to be incompatible, due to the unfullfilness of the maximum prescribed deviations.
