Solution technology of two groove guide pulley production.
Šimonek, Ondřej ; Sedlák, Josef (referee) ; Kalivoda, Milan (advisor)
Technology deals with the production of the two - groove guide pulley for two types of semiproducts. Technological process of production solves the production of the guide pulley from the first gripping of semiproduct to handing over of the guide pulley to the warehouse. Semiproducts are two types of castings with different separating plane. The material of the guide pulley is always gray - cast iron ČSN 42 2420. Production method is cutting operation with CNC machines. The production uses tools with interchangeable cutting tips. The aim of this work is to find the most optimal method of production from both time and economic perspective and to compare the two variants.

Verification of the original technologies used for art castings
Hřebíček, Lukáš ; Mrázek, Martin (referee) ; Horáček, Milan (advisor)
This diploma thesis is describing making of the same art casting by using different foundry technologies/ moulds (ceramic shell mould, several types of plaster moulds including anhydride gypsum and also natural sand mould). In this thesis there is also description of casting the famous piece of bull from “Byci skala” (Bull Rock). The bull was cast into traditional clay mould which is believed to be the original technology. Also the original shape of the bull casting was reconstructed, i.e. a copy of the original bull casting made. As the main achievement of this work is an overview and comparison of several technologies suitable for making art castings.
