The production of a gully
Králíček, Václav ; Jopek, Miroslav (referee) ; Peterková, Eva (advisor)
Aim of the thesis is possible innovation in production of a body of floor gully. Material of the gully is an austenitic stainless steel 1.4301 (X5CrNi18-10). This particular gully belongs to floor drainage portfolio of ACO Industries k.s., which is a world leading company in drainage systems. The current welded variant has been replaced by a combination of conventional drawing and dimpling. The geometry of the drain bottom was designed in accordance with the requirements of the ČSN EN ISO 14159 standard and EHEDG documents on the hygiene of equipment for use in the food industry. Technological calculations were made for the new designed geometry, the bottom of the inlet will be made in one drawing operation together with the dimpling of the pre-made hole. The production process was verified using numerical simulation. Part of the solution was the production of a prototype for testing of the flow rate. During the flow rate test, the requirements given by the standard were fulfilled. Combined tool for drawing and dimpling was designed. The tool is designed for use in hydraulic press Dieffenbacher PO250 II with magnetic tool clamping. The financial savings compared to the current floor drain design are about 243,43 CZK. With a specified production series of 700 pieces per year with an expected increase of 15 % in the following years, the return on investment for the purchase of the tool was calculated to be 2,65 years.

Manufacturing processes of components with a minimum number of tools
Zábojník, Zdeněk ; Drbal, Martin (referee) ; Kalivoda, Milan (advisor)
The bachelor thesis focuses on manufacturing components with a minimal number of tools on a CNC lathe. To demonstrate the production of components with a minimal number of tools, manufacturing procedures for two components, A and B, were designed. Component A is a typical component of simple shape that can be manufactured with a low number of tools. Component B is more complex in shape, and two production variants were proposed for it: one with a higher number of tools and one with a reduced number of tools. For both components were were selected tools, proposed manufacturing procedures and time calculations were carried out. In conclusion, a technical – economic evaluation and comparison of both variants for component B were conducted.

Cognitive deficits in children with visual impairment and the possibilities oftheir early diagnosis
Štrofová, Helena ; Květoňová, Lea (advisor) ; Vítková, Marie (referee) ; Lopúchová, Jana (referee)
The dissertation entitled Cognitive deficits in children with visual impairment and the possibilities of their early diagnosis responds to the need for a tool for the early detection of visual impairment at the level of the visual apparatus in children with cognitive deficits for special pedagogues. The aim of the thesis is to design and verify the reliability and usability of a tool for the early detection of visual disorders at the level of the visual apparatus, which could be used by special pedagogues. Based on them, identify children with an indication for a complete ocular and orthoptic examination. The partial goals are to determine the coincidence of visual impairment with cognitive deficit, to compare the reliability of individual stereotests and to evaluate the practical use of the tool for special pedagogues. The theoretical starting points are current findings on the issue of cognitive processes and their deficits, the visual analyzer and its defects at all levels, with an emphasis on defects at the level of the visual apparatus and the relationship of cognitive deficits to visual disorder in childhood. The research part is based on a tool created to detect defects at the level of the visual apparatus for special pedagogues and to determine its reliability using the quantitative method...

Tool for Software Systems Design
Hala, Karel ; Janoušek, Vladimír (referee) ; Kočí, Radek (advisor)
The Tool for software systems design is an application for visualization of application development. It's main goal is to achieve connection between developer and customer. It should be used to understand customer's needs, prepare work ow of project and behaviour of each class and method using objected oriented Petri nets. In this work we will look on other programs, that focus on similiar topic, we then pick some diagrams and describe how they were implemented. At the end we will disguss possible extension for this tool.

Active Compensation of Tool Deflection
Zarboch, Jaromír ; Marek, Jiří (referee) ; Březina, Tomáš (advisor)
This paper deals with design of tool deflection compensation system for milling spindle C1, provided by company TOSHULIN, a.s. A simplified simulation model of the spindle supplemented by compensatory elements was built by using programs ANSYS, MD ADAMS, Matlab/Simulink. As action elements there were use three piezoactuators each controled by PID controler. Efficiency of this compensation system was verified based on performed simulations.

Suggestion of technology for manufacturing parts of a hydraulic press
Gryc, David ; Mouralová, Kateřina (referee) ; Zemčík, Oskar (advisor)
An introduction of hydraulic press and description of his main parts. An analysis of the given components and a proposal for the most suitable intermediate was made. A selection of tools and gauges for individual operations has been done. A proposition of manufacturing process and enumeration of machines times was proposed. Economic evaluation containing costs for intermediate, tools, workmen’s wages and energy for operating machines has been calculated.

Production Concept of Special Machining Device for Making of T-Channel Detail
Opršál, Radek ; Osička, Karel (referee) ; Sedlák, Josef (advisor)
The objective of this diploma thesis was the design of a special machine tool that increases the efficiency of the production of a T-slot detail on the part of the clamp body. The thesis deals with the current production of this component as well as the description of the material, the machines that are used and the technological process. The next part focuses on the description of the new special machine tool, its production, heat treatment and the presentation of used indexable inserts. Another part analyses the production innovation that was comprised of the comparison with the former machine tool to the new one. The thesis concludes with a technical and economical evaluation of the former and innovated production.
