Utilisation of innovative materials at design of bohring machines
Tobolka, Ondřej ; Marek, Tomáš (referee) ; Marek, Jiří (advisor)
Thesis solves an issue of application unconventional materials used in horizontal boring machine design. Chosen problem is solved step by step from general selection of suitable material for supporting structure. The selected material is applicated on WFT 13 CNC machine design from production of Fermat and it is created 9 conceptual options of machine’s frame. Finite element method is used for analysis of conceptual options. Based on data from analyses, the best option is selected for constructional part with use of multi-criteria PATTERN method. Constructional part of thesis elaborates on the design of selected conceptual option and gives recommendation for essential processes used in development and production of sandwich structures. The master’s thesis comes with new construction solution for supporting structure of selected machine and especially insight in development and production of new unconventional materials in horizontal boring machines design.

The new concept of maintenance and operation of manufacturing technologies
Klus, Jakub ; Marek, Tomáš (referee) ; Marek, Jiří (advisor)
This diploma thesis deals with a new concept of maintenance and operation of production technologies, where spare parts are manufactured using rapid prototyping methods. The options are compared with currently used methods. Furthermore, methodological recommendations are written on how to proceed with the application. The aim of the work is to evaluate the concept and confirm the theoretical assumptions on a case study.

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.

PřekladačVypnout okamžitý překladPalletizing of the tilting head of a milling multi-purpose machining center with a horizontal spindle axis
Hynšt, Tomáš ; Marek, Tomáš (referee) ; Marek, Jiří (advisor)
This diploma thesis deals with palletization of heavy workpieces that are used by multi-purpose machining centers. The final outcome introduces a suitable option for palletization heavy workpieces of multi-purpose machining centers. In the first part of the thesis is draft of machining centers with parameters which were chosen by exploration of market for selecting suitable solution. The second part of thesis is dealing with a detailed draft palletization made by parts of exploration of market then design palletization system and design pallet changer. The designed construction of pallet changer is dimensioned with help of analytical calculating methods and numerical simulations methods. Outcome palletization system allows automatic change of twenty tons workpieces including pallet between two storage places.

Kindergarten
Marek, Tomáš ; Donaťák, Vladislav (referee) ; Donaťáková, Dagmar (advisor)
The subject of the diploma thesis is the elaboration of project documentation for the implementation of the new civic amenities of the Nursery School in the cadastral area of Plácky in the territory of the town of Hradec Králové. The building is designed as a stand alone divided into 4 segments with two above-ground floors. Kindergarten consists of 3 separate departments with a total capacity of 60 children and 1 unit for hobbies with a capacity of 20 children and their facilities. The object is based on the base passages. All brick structures are made of brick blocks Porotherm and the heat insulation is added to the perimeter shell. The internal staircase is monolithic, reinforced concrete and external prefabricated steel. The object is roofed with a flat roof and the support element consists of reinforced concrete pre-prestressed panels SPIROLL. Drawing part is processed in ArchiCAD program, visualizations are processed in Lumion program.
