Manufacturing of consumer accessories using rapid prototyping technology
Koubek, Michal ; Dvořáček, Jan (referee) ; Sedlák, Josef (advisor)
My bachelor thesis is focused ou the production of applied supplements not commonly available. The applied supplements were modelled by Autodesk Inventor graphic program, transferred to, outcoming format of data and them produced by Rapid Prototyping technology by using fused deposition modelling aditive method. The part of my thesis i salso production of silicon form of chosen part by means of vakuum moulding system. My thesis is finished by technical and economical evaluation comparing the price, for which these supplements can be obtained in the market or produced by means of 3D printed uPrint by using fused deposition modelling method, which is available at Brno Universit of Technology – Faculty of Mechanical Engineering.

Cutting force analysis when 5-axis milling
Dvořáček, Jan ; Kalivoda, Milan (referee) ; Polzer, Aleš (advisor)
The diploma thesis is focused on machining using the ball-end shank mill. Content of the preliminary part of the work is a shank mill characteristic and a consequent part shows a splitting of ball-end milling cutters, its application, the cutting tool geometry and a characteristic signs of machining. The cutting force model of the ball-end mill is presented as well. A part of proposed model is the conversion of the resultant force too. Practical part is aimed at cutting force analysis of the ball-end mill and the main purpose of this part is a quantification of the cutting force for different work piece tilt angles while milling is performed.

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.

Usage of modern technologies for manufacturing the blades of fishing baits
Barcuch, Jakub ; Dvořáček, Jan (referee) ; Sedlák, Josef (advisor)
The aim of this thesis was to design a number of blades for fishing baits in 3D parametric CAD system Autodesk Inventor 2010 and their production with using the additive technology of Rapid Prototyping. The method Fused Deposition Modeling will be used to produce the master model blades. The silicon molds for the production of resin casings will be created for blades with compliant properties. The work contains an overview of commercially available Rapid Prototyping methods, their brief description, advantages and disadvantages.

Economic comparison of manufacturing the machine parts on machine tools in the company Frentech Aerospace s.r.o
Novák, Lukáš ; Dvořáček, Jan (referee) ; Sedlák, Josef (advisor)
Bachelor thesis deals with economic assessment of three different methods of production a given part. Two methods of production are given by Frentech Aerospace s.r.o. The third method is designed to lower the final price of the component. Machines are selected from the offer of Mazak machines in the new manufacturing process. Developing of program for manufacturing workpiece on machine tools belongs to this thesis. The goal is to upgrade the existing method of production the specified component. Bachelor thesis is concluded technical-economic evaluation of all three alternates.

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.
