Present state of investment casting technology - wax patterns
Procházka, Zdeněk ; Helán, Jiří (referee) ; Horáček, Milan (advisor)
The subject dealt with in the bachelor degree thesis covers technology of investment casting with a special focus to the problem of wax patterns. Based on expert analysis, this case study focuses on the most advanced facilities and materials used for this particular phase of technology as well as basic methods of wax materials testing.
Production of Pattern Equipment for Casting Pump
Suchomel, Martin ; Dvořák, Jaromír (referee) ; Kalivoda, Milan (advisor)
The bachelor thesis focuses on the design of foudry technology, design and production of pattern equipment for castiong of pump from cast iron ČSN 42 2420. The practical part elaborates design of technology and pattern equipment in CAD system SolidWorks. Simulation of casting was made in CAE system ProCAST. For design of milling technology was used CAM system HSMWorks. On the CNC machines was machined model, core box and underlay. Result of my thesis is pattern equipment for moulds and cores for the casting. In the end was made molds, cores and five samples of casting was casted.
PATTERN PAINT ROLLER LAB
Giacintová, Zdeňka ; Arndt, Jan (referee) ; Ondrík, Jozef (advisor)
My work focuses on the technique of pattern paint rollers and their historical context. Above all, the work presents an opportunity for me to engage with a phenomenon that was very popular in its time and to explore its potential beyond traditional perceptions. Through a series of tests, I experimented with creating new designs and explored the possibilities of this technology, which included, for example, tests of the materiality and size of the roller matrix or the transfer of the decor from its typical interior setting to an exterior environment.
Additive technologies and their using when making prototype castings
Čagánek, Radim ; Horenský, Jiří (referee) ; Horáček, Milan (advisor)
This bachelor´s thesis deals with Rapid Prototyping systems and their uses in foundry. This thesis describes three most significant RP systems, on which is explained principle and distribution of them. The another part of the thesis describes how is RP systems useful in production of sand molds, ceramic shells and permanent mold.
Surroundings / Fragments of Life / Vernacity
Pelikánová, Šárka ; Nikitinová, Alice (referee) ; Artamonov, Vasil (advisor)
The collection of paintings entitled SURROUNDINGS is based on my long-term interest in observing the everyday world. In the diploma work, I return to my family, to my home village. I look at my surroundings with gratitude and nostalgia. With gratitude for such a carefree, loving childhood, for the diligence that our parents taught us from an early age. I look nostalgically at what remains the same around the village so far, and regret at everything that changes. During the creative process, I explore maps, recording the shapes of ponds, houses and roads. However, I narrow the resulting set of paintings to the local forests, their transformations and work in them. Paintings with repeating patterns look at first glance with an emptied aesthetic impression, like a purely thematic prank. In fact, I bring personal experience into this decorative repetition, repetitive family stories that have happened, are happening and that I want to capture with this stylized form.
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.
no noon on
Janechová, Lucia ; Houser, Milan (referee) ; Štindlová, Marie (advisor)
The thesis focuses on the theme of sun. We perceive the sun in many different ways according to its position on the sky, to where we are located or simply depending on our current mood. In paintings and objects I look for ways to capture it's visual form or the imprints of feelings it's capable of creating. For that I use spiky or round branch-like shapes as the variations of the sun rays, in the centre of paintings is usually a circle. I combine acrylics and oil with dry pastel, which enable more relaxed and free strokes. In effort to expand the scale of medium I included materials like copper or concrete in my work. The series is therefore finished with relief almost-objects and a copper “gate” the sun figuratively passes through at noon.
Trends in manufacturing of non-permanent wax patterns in investment casting technology
Halaška, Jan ; Šmatelka, Jakub (referee) ; Horáček, Milan (advisor)
Bachelor’s thesis describes the most used wax blends and equipment for manufactory of sophisticated castings. The thesis includes two major sections and these are wax blends and wax patterns. The aim of this thesis is to develop a literary review focused on the most advanced equipment and raw materials used in the investment casting technology with a focus on the manufactory of wax pattern.
Possibilities of using modern methods in manufacturing of prototype castings
Maincl, David ; Němec, Jiří (referee) ; Horáček, Milan (advisor)
Rapid prototyping is a set of technologies , which is an essential part of modern foundry industry . It allows you to shorten the time between demand and fabrication of prototype parts. The aim of this work is to develop a literature search focused on the application of these technologies in the foundry manufacturing of prototype castings.
Proposal of Software Improvement Support for a Trading Strategy in Commodity Markets
Levek, Petr ; Kotlík,, Josef (referee) ; Škapa, Stanislav (advisor)
The Bachelor work is focused on proposals to improve software support and the efficiency of investment in commodity exchanges worldwide. The aim is to propose software improvements for selected software used for trading. Improvements will be made on the basis of analysis and comparison, the currently commonly used traders software for trading on world stock exchanges, with a focus on finding and proposing modules that improve the strategies used during trading. Based on the introduction and the use of these improved modules, that are currently not available, will increase efficiency of work for traders and reduce potential risks of investments used.
