Prototype part and made by method rapid prototyping
Kočárek, Karel ; Dvořáček, Jan (referee) ; Kalivoda, Milan (advisor)
This bachelor thesis is dealing with prototype stage during development of reduction part for gas flow control, which is positioned in gas boiler downstream of the valve. Thesis is focused on additive manufacturing. Basic technologies, their attributes and procedures which are necessary to be followed are described here. Practical part is composed of 3D model creation in CAD software, export of model to STL format and its inspection for compactness. After that 3D model is sent to printer and functional components are made, that can be used for application verification and for detection of possible design deficiencies before the mold assembly is made.

Production of rotational parts on a CNC machine
Hort, Zbyněk ; Dvořáček, Jan (referee) ; Kalivoda, Milan (advisor)
The main theme of this thesis is a design of rotary part (shaft) production. The study contains the choice of semi-finished product, technological procedure, manufacturing instructions, design and description of machines and tools. It also includes a production drawing of a shaft and NC program by which a functional sample was produced. The economic evaluation is at the end of the thesis. The thesis meets all requirements needed for shaft production using CNC machines.

Process fluid on a CNC machines
Lolek, Jan ; Dvořáček, Jan (referee) ; Kalivoda, Milan (advisor)
The work is focused on the classification of process fluids for CNC machines, their characteristics, suitability particularly in the machining operations and workpiece material. The next section evaluates the contamination of process fluids in companies, which can occur during machining. The next chapter provides an overview of work equipment used in modern CNC machines and is used for filtration and maintanance of process fluids. In the last part are returns of investment on a smaller filter equipment and a central system for several machines. In this chapter is evaluated with examples from real productions .This issue was discussed with the experts from industry, especially employees of the company IKV Ltd., which is a supplier of accessories for CNC machines. Equipment supplied by this company is primarily used to reduce the defects of industrial production.

Design technology for the production of custom advertising article
Konečný, Lukáš ; Dvořáček, Jan (referee) ; Kalivoda, Milan (advisor)
The project worked out in the framework of the Bachelor's study presents a proposal of producing technology of an advertising article in shape of a razor blade made from stainless steel 316L, in jewellery commonly called surgical stainless steel. Expected batch production is 100 pieces. In the thesis is compared technology for the production on a knee-type CNC milling machine with a laser cutting machine. A production drawing of a razor blade is given as a material for manufacture. A part of this project is an economic evaluation and a conclusion of suggested technology.

Superhard cutting materials
Mlčoch, Petr ; Dvořáček, Jan (referee) ; Humár, Anton (advisor)
This bachelor thesis deals with superhard cutting tool materials, which include diamond and cubic boron nitride. It is divided into three parts. In the first one there is a short summary of cutting tool materials currently used for machining. The second part pursues sorts, production and properties of superhard cutting materials. The last part represents superhard cutting materials in the offer of two important producers of cutting tool materials and two producers of cutting tools.

Application of modern technologies for the production of the release mechanism of a car door
Hruška, Lukáš ; Dvořáček, Jan (referee) ; Sedlák, Josef (advisor)
The Bachelor`s work concerns the production of door ulocking mechanism for a passanger car Renault Megane. From the viewpoint of function and the necessity to keep the exact dimensions of chosen parts were the data for the production obtained by digitalization of a real product. The digitalization was carried out by the contactless optical 3D scanner of GOM mbH company, specifically the developmental series ATOS II Triple Scan. The pin`s data were obtained from parametrical program Autodesk Inventor 2011. For the production of Master models the additive technology Rapid Prototyping, method Fused Deposition Modeling, was used. Master model of the handle was used for the production od solicon mould, that was used for casting of required number of handles from resin. The end of the work deals with a technical and economical assessment of the production. A part of the work is also a summary of the most used methods of Rapid Prototyping and Reversible Engineering.

Production of functional equipment for food processor using Fused Deposition Modeling
Štancl, Václav ; Matuška, Martin (referee) ; Dvořáček, Jan (advisor)
This bachelor thesis deals with the production of component using the Fused Deposition Modeling method and economic comparison of this production to other manufacturing technologies. This component is accessory of manual food processor, which is due to poor clamping diameter unusable. In Autodesk Inventor model was created, that is, with the exception of altered functional dimensions, identical to the original parts. The final accessory of beater was made by using the Fused Deposition Modeling method with uPrint equipment.
