A design of single-purpose saw
Rakhmatullin, Artem ; Štěpánek, Vojtěch (referee) ; Tůma, Jiří (advisor)
This thesis focuses on the design of a single-purpose saw for cutting grooves on aluminum profiles. The work includes the examination of different types of saws, the examination of various design alternatives, the identification and selection of the most advantageous variant, the subsequent creation of a detailed design based on the chosen solution and a comprehensive evaluation of the resulting design. The desired result is a saw design that prioritizes factors such as ergonomic comfort, safety, precision and operational efficiency, ensuring a complete and efficient solution.

Design of platform for handheld circular saw
Koutecký, Vojtěch ; Pavlík, Josef (referee) ; Pavlík, Jan (advisor)
The aim of this work is an effort to create a mobile and space-saving workbench for clamping a hand-held circular saw with angle and height variation of the saw blade. As part of the technical report with the relevant calculations and drawings of the main parts of the worktable. Table will contain auxiliary cables (also dimensionally adjustable) for longitudinal cutting. This set will serve as the "saw" for the simple joinery operations or as a cheaper competitor aforementioned saws.

Progress of welding in shipbuilding
Urban, Václav ; Kubíček, Jaroslav (referee) ; Kovář, Petr (advisor)
This work deals with the methods of welding in shipbuilding, summarises the basic techniques used for welding of the SAW, MAG, MIG, TIG, laser, Laser-Hybrid. It describes the properties of welded material. Especially the materials HY80 and HY100. It follows from the filler materials. In particular materials Spoolarc 95 and 120. Particular emphasis is placed on the method of Laser-Hybrid, its properties and use in shipbuilding. Finally, describes the method of welding aluminium using FSW, preparation of welded surfaces and producting of sandwich panels.

Design of a band saw with an automatic exchange of saw blades
Šula, Martin ; Merenus, Ondřej (referee) ; Kočiš, Petr (advisor)
The bachelor thesis deals with the design of a band saw with automatic exchange of three saw bands for cutting of steel rods or profiles. It also deals with the design of solution variants, design of selected variant and calculation. The result of the calculations is the safety check with respect to the elastic limit states, the fatigue control and the bearing life calculation. It also contains an economic assessment of the variant.

Numeric simulation of surfacing turbine rotors pinot pins
Tkaný, Jan ; Mrňa, Libor (referee) ; Daněk, Ladislav (advisor)
The master´s diploma thesis elaborated as the master's degree M-STG Manufacturing Technology solves surfacing problems in the simulations of surfacing turbine rotors pinot pins. The work was seen as a preparatory work before the real surfacing. Topic commissioned by Siemens Industrial Turbomachinery Ltd. For welding plates test has been used the method of SAW and the base material was identical to turbine rotor material, X22CrMoV 12-1. Additional material was Fluxocord 42. Simulations were carried out in programs SYSWELD and Visual - WELD. The output of the simulation software are temperature and stress fields, material structures and creations of the CCT diagrams at the base material, filler material, and mixed area.

Modern detection methods of energetic materials
Šesták, Jozef ; Bednařík, Karel (referee) ; Friedl, Zdeněk (advisor)
The review of modern detection methods of explosives was composed. Firstly the thesis deals with the detection methods commonly used in forensics science such as gas chromatography, mass spectrometry, ion mobility spectrometry, Raman spectroscopy and mainly their innovations. Then the thesis is focused on simple but very sensitive methods using fluorescence and chemiluminescence. At the end a methods as the results of a latest research are mentioned. The main of them are micro cantilever sensors and differential reflectometry. Security and counterterrorist warfare is main point of thesis.

Numeric simulation of the turbine rotor surfacing
Durajová, Věra ; Slováček, Marek (referee) ; Daněk, Ladislav (advisor)
The project elaborated in frame of engineering studies, solves the problem of restoration of the damaged hinge groove blades, and the surfacing of cylindrical faces of the SAW method, using additional material TOPCORE 838 B. The turbine rotor is made from steel with high resistance temperature 30CrMoNiV5-11. Based on literature studies and issues surfacing calculation, it was established that will preheat the material. The issue was solved by using simulation program SYSWELD.
