Design of extend the machine with the possibility of separating 3D prints
Gonda, Josef ; Tůma, Jiří (referee) ; Pavlík, Jan (advisor)
Separating of the metal 3D print from the print plate is a key step in most metal 3D printing methods. The author's goal is to design a device - a clamping mechanism that expands the functionality of existing band saws for metal by the possibility of comfortable separation of prints. In the beginning of the work, the author discusses the methods of metal 3D. Furthermore, the author focuses on the analysis of the market in the given issue and a brief description of the existing solutions of world/competing band saw manufacturers. Subsequently, the choice of a specific band saw is justified and the basic properties of the mechanism are determined. An essential part is the design of solution variants and the selection of a variant based on multi-criteria analysis. Furthermore, the author analyzes the design solution of the selected variant with a description of partial details, where he emphasizes compliance with the specified conditions and product optimization.

Design of a band saw with an automatic exchange of saw blades
Szabari, Šimon ; Halamíček, Lukáš (referee) ; Kočiš, Petr (advisor)
The aim of this thesis is to conduct a research in the field of band saws with a folding arm and to design a band saw with an automatic exchange of saw blades. In the first part of the project there is processed an overview of the division and distribution of band saws available on the market. The second part of the thesis is focused on the design of two variants of band saws, their evaluation, development of selected variant and basic design calculations. The result of this work is a 3D model of band saw, assembly drawing and drawings of three saw bits and also an animation of both variants.

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.

Safety of band saw cutting machine
Bezrodný, Roman ; Bradáč, František (referee) ; Blecha, Petr (advisor)
This Master's thesis summarizes the current legislative requirements resulting from the Directives of the European Parliament and Council and the legislative requirements of the Czech Republic in the field of cutting machines, with a focus on band saws. Furthermore, there is also an analysis of the requirements of the relevant harmonized standards. For information sorting, check lists for the construction of a band saw and a process map of the construction of the saw have been made. In the last part of this work, the selected safety applications were completed for the band saw.

Economic study of the mobile band saw utilization in conditions of CR
Lojda, Martin ; Holopírek, Jindřich (referee) ; Chladil, Josef (advisor)
The thesis deals with possibilities of using of mobile band saws. An economic analysis of band saw utilization for woodworking was carried out. Further the work evaluates and analyses the technological string of lumber production in a selected area. In the first part there is a study of current state of technological string of saw timber production. The second chapter deals with the evaluation of state in consideration of woodworking in relation to selected location of production facilities. The third part is focused on evaluation of possibilities of mobile band saw utilization that is carried out on Husqvarna SMB - 70. The fourth section describes technological variations and tries to determine criteria for choosing of the best variant. It details opportunities of a small - grower that tries to find the most suitable variant by selling a wood, so as it brings the maximum profit. The work deals with various possibilities of timber production in which the band saw is included. Technical parameters of particular saws are described here. And by means of economic parameters the most suitable technology for sawn wood production is determined. The goal of this thesis is to choose a suitable technology for timber production based on economic analysis and with regard to conditions of the processing plant.

Optimization of the laser cutting technology of tubes with a square cross section
Podaný, Petr ; Sigmund, Marian (referee) ; Mrňa, Libor (advisor)
The master thesis deals with the design and manufacture of tabbed joint in the profile with a square cross section using laser cutting. They examine their suitability and impact on the following MAG welding operation in terms of efficiency and accuracy. The theoretical part provides basic information about lasers used in industry and laser cutting methods. There is also a section dedicated to laser apparatus for tube cutting along with problematic about the laser cutting profiles. The experimental part describes the procedure of designing tabbed joint, making samples and measuring them. In the end, the individual samples are compared in terms of angular deflection after welding. The thesis also contains a technical-economic evaluation, where the costs of individual operations are quantified.
