Optimisation of machining process for an industrial application and a CNC machining centre
Soukupová, Veronika ; Sliwková, Petra (referee) ; Píška, Miroslav (advisor)
Tato diplomová práce byla vypracována v průmyslovém kontextu, během stáže ve firmě Metso. Zlepšení obráběcího procesu zajišťovacích šroubů bylo cílem této práce, aby byla umožněna budoucí automatizace zakládání obrobku do stroje. Zlepšení bylo zhodnoceno na základě úrovně autonomie během obrábění, eliminace neprogramovaných zastavení stroje operátorem a dostačujícího odvodu třísek. Implementace automatických systému do číslicově řízeného obráběcího centra umožňuje zvýšení produktivity. Před automatizováním obráběcího procesu však musí být proces optimalizován. Zejména dostatečná fragmentace třísek a jejich evakuace jsou klíčové. Dlouhé nedělené třísky můžou poškodit systémy jako například automatický měnič nástrojů, dopravník třísek nebo průmyslového robota. Dostatečná lámavost třísek může být zaručena správným výběrem technologie a strategie obrábění, výběrem řezného nástroje a řezných podmínek pro daný materiál obrobku.

Realization of educational problem based on preloaded bolted joint apparatus
Žaba, Tomáš ; Náhlík, Luboš (referee) ; Vaverka, Michal (advisor)
In the master’s thesis an educational task concerning an experimental apparatus for quantity measurement in preloaded bolted joint is realised. In terms of its preparation an innovation of the apparatus leading to an easier and faster pretension realisation was implemented. The educational task for students and also teaching material were produced. The educational task itself consists in experimental confirmation of the relation between the tightening torque and the caused pretension. An FEM model simulating an apparatus flange deformation by given pretension was designed to verify the experiment. The thesis also contains information about the preloaded bolts, pretension elicitation methods and pretension control methods.

Airport Departure Hall
Čech, Ondřej ; Šmak, Milan (referee) ; Barnat, Jan (advisor)
The bachelor thesis deals with the design and assessment of steel load bearing structure of the departures hall of the airport. It is a purlin system consisting of sloping trusses of curved shape with overhangs that make up the awning above the entrance to the building. Truss to span 18 meters is welded from pipes. The steel used in the project is S355. For the design was used Scia Engineer software, in which was created a spatial model of the structure.

Glazier's Hall
Kelar, Petr ; Pilgr, Milan (referee) ; Barnat, Jan (advisor)
The bachelor's thesis deal with structural design of Glazier's hall. Dimension of the hall are 9,24 m x 24,51 m. The basic material is steel S355. The main frame is three-hidged frame. Each frames are connected by the purlins and girts. Spatial rigidity of the structure is provided by the rigid frame corners and sway bracings. Part of the design is crane runway for bridge crane from Demag company with load capacity of 5 t. Structure i designed in compliance with valid standards of ČSN EN and corresponds with ultimate and serviceability limit state. For structural design was used software RFEM 5.07.03 of Dlubal company.

The Structure of the Atypical Family House in Vrchlabí
Vondráček, Vít ; Hron, Lukáš (referee) ; Šmak, Milan (advisor)
The subject of master’s thesis is design and assessment of steel load-bearing construction of atypical family house in Vrchlabí. Structure is designed as multi-storey steel structure, cooperating with stiff concrete core. The design was considered in four different options which combines possibility of using steel, steel and timber with different way of stiffness for whole structure. There is also composite steel-concrete alternative floor trimmer for selected option. Design and assessment was conducted in accordance with the applicable standards and by using software Scia Engineer.

Use of Slack API for HeadlessCMS
Hruška, Jozef ; Burget, Radek (referee) ; Bartík, Vladimír (advisor)
The aim of this thesis is to create a content management system with open application interface (Headless CMS) and capability of content management inside Slack application. Installation and use of system does not require any configuration by user. Open (public) and closed (hidden) application interface is built following GraphQL specification. The public interface is read-only which means it is not possible to insert or modify data through this interface. The output of this work is a fully functional prototype implemented with tools as React and Node.js with focus on user-friendly interface.

Timber foot bridge over a wolf run
Mynaříková, Alice ; Šmak, Milan (referee) ; Straka, Bohumil (advisor)
The subject of this diploma thesis is the construction of a timber foot bridge over the wolf run in the Šumava National Park. The total length of the bridge is 240 m with two ground plan bends. The foot bridge includes three viewing decks, two of which are covered with shed roofs. The foot bridge is divided into 16 segments. Each segment is 15 m long with a width of 2.2 meters. The ground plan dimensions of the viewing decks are approximately 15x7 and 15x11 m. As the main structural material has been chosen glued laminated timber of the strength class GL28h, other elements are made of solid timber of the strength class C24. The thesis includes an introductory document, options analysis, technical report, static analysis, bill of material and drawings.

Removal of the masonry pillar in the front wall of the apartment house
Vítková, Barbora ; Bažant,, Zdeněk (referee) ; Strnad, Jiří (advisor)
This thesis focuses on the removal of the masonry pillar from the front wall of an apartment house. The masonry pillar should be replaced with two steel columns in a given axis distance. The parts of the thesis are a technical report, a static calculation and a graphic documentation. The description of the current object and the proposed solution is included within the technical report. The static calculation deals with a calculation of the strain and the enhancement of the current ferroconcrete lintel on the ground and first floor. A proposal of the solution, which is determined by the static calculation, is evident from the graphic documentary.
