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.

Production of plough share screw
Hladík, Milan ; Jopek, Miroslav (referee) ; Forejt, Milan (advisor)
The bachelor's thesis presents a design of plow screw production technology used to attach the blade to the plow frame. The screw is made of structural steel 14,140, in a production series of 120,000 pcs / year. From the possible technologies, the technology of volume cold forming was chosen. From the literature sources of the issue of volume cold forming, the optimal procedure of screw production was proposed. With the help of design, technological and control calculations, a machine was designed and subsequently a production tool, for which drawing documentation was prepared. With the help of technical - economic evaluation, the costs of component production were compared using volume forming and machining.

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 roof structure of a bus station with facilities in Vrchlabí
Vondráček, Vít ; Hron, Lukáš (referee) ; Šmak, Milan (advisor)
The subject of bachelor's thesis is design and assessment of steel load-bearing construction of bus station in Vrchlabí. It is designed as a co-operating load-bearing steel pillar based structure with the construction of the outdoor platform. The design was considered in four different options for inner building. Followed was mainly the weight of inner structure with respect to the roof deck. The selected option is then incorporated into the scope of the entire structure. Design and assessment was conducted in accordance with the applicable standards and by using a computer program Scia Engineer.
