Manufacture of cylinder head casting for engine renovation Jawa 50
Pastyřík, Petr ; Myška, Martin (referee) ; Bořil, Petr (advisor)
This project elaborats the manufacture of a cylinder head casting for an engine renovation of Jawa 50. Based on the literary pursuit of suitable foundry technologies and using 3D printing in foundry a casting production technology was designed and the cylinder head was made. The part was designed in the CAD software and then printed on a 3D printer. The printed model was formed in ceramic shell form, then melted and the form was annealed. After that the cast was casted. The last operations were fettling and finishing machining.

Cleanliness of steels manufactured in vacuum induction furnaces
Pastyřík, Petr ; Záděra, Antonín (referee) ; Pernica, Vítězslav (advisor)
The topic of this thesis is the micropurity of steels manufactured in vacuum induction furnaces. The thesis describes 3 processes of steel melting using the same type of steel with different production parameters. Subsequently, samples were prepared and based on those samples the micropurities of the melting processes were evaluated. To obtain the results image analysis and electron microscope were used. Furthermore, elemental analyzer was used to measure the content of oxygen, nitrogen, sulphur and carbon. Afterwards, a discussion on micropurity and comparison of the melting processes is presented. In the conclusion section there are some possible suggestions concerning operation of the university foundry.
