Design of replicated production of the selected part and verification of shape and dimensions using optical 3D scanning methods
Šrenk, Jakub ; Fiala, Zdeněk (referee) ; Slaný, Martin (advisor)
This work is engaged in the prototype casting of resin with usage of reverse engineering technology and rapid protopyping. Surface quality and dimensional accuracy was optimized in a production process. The technology of 3D scanning, rapid prototyping, soft tooling and finishing methods is discussed in the theoretical part. Then in the practical part there is analyzed manufacturing process of the selected component for replicated production. 3D scanning, additive technology, soft tools and surface finishing methods were used in the manufacturing process. In the last step, the dimensional accuracy is evaluated and also the technology for serial and piece production was chosen.

The unconventional Method of Cutting Water Jet
Prax, Ondřej ; Slaný, Martin (referee) ; Osička, Karel (advisor)
The master thesis contains a literature search dealing with the unconventional technology of water jet cutting. The first part is aimed to description of the water jet technology and shows the possibilities of controlling and awarding data for cutting. Follows the chapter about the influences of the input parameters to a surface quality and machining accuracy. The thesis also giving an account of ecological factors of the water jet cutting. The description of the whole technology for production of the sprocket is a part of the thesis. The last part of the thesis is solving the economics of the water jet cutting technology, especially for production of the sprocket with comparing dependency of the cutting conditions.

Design and production of experimental axle part
Volfík, Jiří ; Slaný, Martin (referee) ; Zemčík, Oskar (advisor)
The content of this diploma thesis is a design of construction and selection of suitable material for upper-carrier part used for racing vehicle, produced by FDM 3D printing with the alternative option to replace an existing part, which was produced by conventional technique of CNC machining. Various versions of the experimental part are analyzed by FEM and compared in terms of safety coefficient with target to select the most appropriate construction design. The chosen version of the model is at the end compared with already existing part, which was also analyzed by FEM.

Cutting of Water Jet
Zouhar, Ondřej ; Slaný, Martin (referee) ; Osička, Karel (advisor)
The work developed in the master's program, describes the technology of water jet cutting. The theoretical part deals with the description of this technology and it explains the basic concepts used in this field. The practical part was designed to verify some theoretical knowledge. Therefore, several experiments were performed, while there was studied the influence of abrasives on the final quality of the surface and the level of the generated noise. The practical part was completed by the production of the selected component and its technical and economic evaluation.

On The Analyse of High Productive Reaming Technology
Gashkova, Irina ; Slaný, Martin (referee) ; Píška, Miroslav (advisor)
Diplomová práce se zabývá analýzou technologie vysoceproduktivního vystružování. V rámci práce byly provedeny testy vystružování za různých technologických podmínek (vc=40, 60, 80, 100 m/min; f=0.2, 0.4, 0.6, 0.8 mm) na materiálu austenitické oceli DIN 1.4404 při použití vystružovací hlavicí MT3. Jednotlivé operace vystružování byly porovnány z hlediska parametrů jako tlačná síla, krouticí moment, výsledná drsnost obrobeného povrchu a dále z hlediska tvaru třísky. Následně byly vypočítány průměrné hodnoty a směrodatná odchylka naměřených parametrů. Dále bylo provedeno porovnání pomocí diagramů. Výsledky ukazují lepší kvalitu, nižší drsnost povrchu (Ra 0,37 µm) a méně zdeformovanou třísku při pomalejších řezných rychlostech (40 m/min) a menším posuvu na otáčku (0,2 mm). Výsledky také ukazují nárůst tlačné síly a krouticího momentu za uvedených technologických podmínek. Při zvyšující se řezné rychlosti vystružování tyto silové účinky klesají.
