Desing and Production of Plastic Adapter to Floor Nozzle
Černý, Martin ; Sliwková, Petra (referee) ; Sedlák, Josef (advisor)
This work deals with the design and manufacture of prototypes of plastic reduction to the floor nozzle. Individual shapes and dimensions of the reduction are designed and constructed in 3D parametric software Autodesk Inventor. Models of reduction are produced using an additive method of Fused Deposition Modeling utilizing a 3D printer uPrint. Work is completed techno-economic evaluation with the subsequent analysis and overall evaluation of the applied technology.

Manufacturing of Components Using Rapid Prototyping
Peňáz, Jan ; Sedlák, Josef (referee) ; Kalivoda, Milan (advisor)
The bachelor thesis deals with solution of manufacturing prototype using three technologies. Two of them are additive technologies using principles of Laminated object manufacturing and Fused deposition modelling. The third technology was milling. Model of reversible turbine was used as a base for manufacturing. CAD system SolidWorks was used for the model creation, where output formats were SLDPRT and STL. For error check of STL data software MiniMagics was used. For preparation of 3D printing data softwares SD View and Catalyst EX were used. CAM system SolidCAM was used for creation of machining strategy. Devices used for manufacturing of prototypes were 3D printer Solido SD 300 Pro, 3D printer Stratasys uPrint and 5axis mill Hermle C20U. Print on 3D printer Stratasys uPrint the most advantageous technology for manufacturing one prototype.

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.

The Production using 3D Printing of Fixture for Shaping Plastic Pipes
Tretera, Robin ; Sedlák, Josef (referee) ; Kalivoda, Milan (advisor)
This Bachelor thesis compares two options in production of shaping form for plastic pipe - handmade production versus 3D print technology (specifically DMLS method). The thesis contains detail description of the final part and shaping form with pros and cons of both production methods. Handmade production is more suitable for serial production with its lower price. In time pressure 3D printing comes up with its fast and repeatable results.

Analysis of the surface after laser cutting
Narovec, David ; Sedlák, Josef (referee) ; Osička, Karel (advisor)
This diploma thesis discusses laser cutting and the consecutive surface treatment of cut parts. The theory of laser cutting is described in the first part of this thesis, including laser history and the laser emergence principle. Cut parameters and the influence of the laser cutting on the material are described later on. The next part describes the laser cutting technological possibilities and other laser technology utilization options are outlined. In the last theory part, metal surface treatment used in the experiment is covered. Coating thickness is evaluated in the practical part of this thesis, as well as roughness, microhardness, chemical microanalysis and metalography. The evaluation of the results achieved, and optimal surface treatment execution suggestions are addressed in the last part of this thesis.

On the Effective Machining of New Ceramic Materials
Sámelová, Vendula ; Sedlák, Josef (referee) ; Vrba, Vladimír (referee) ; Humár, Anton (advisor)
Advanced ceramics have long held the front of the list of promising materials for high-tech applications. The most common problem is the high cost of design, production and machining of advanced ceramics parts. The main sense of advanced ceramics processing techniques development is affordable, high-volume production. The dissertation is focused on SiC silicon carbide grinding. SiC is used in the design of machine parts due to its excellent properties The deep knowledge of the diamond wheel grinding process is important because it is one of the finishing methods and therefore has a direct impact on the quality and strength of the SiC parts. The key issue here is the overall surface quality of the parts after diamond wheel grinding and the knowledge of the factors that influence the surface quality. These include, in particular, grinding vibrations. The main purpose of the thesis is to create a system of specific scientific and technical information, which will allow applying optimal technological procedures in the processing of ceramic components. The theoretical part of the thesis contains an analysis of the current state of the art in the advanced ceramics machining area, detailed analysis of the ceramics grinding with diamond grinding wheels, signal analysis theory and analysis of surface quality assessment methods. The experimental part contains analysis and discussion of the results obtained during the monitoring of the silicon carbide grinding process with a diamond grinding wheel. Various diagnostic methods have confirmed the presence of vibrations at a frequency close to the speed frequency of the grinding wheel, which had a significant, negative effect on the samples surface quality. Vibration diagnostics has identified a specific source of vibration (clamping of the workpiece) and it has been removed subsequently.
