Layout solution of a small workmanship within a given company
 Urban, Antonín ; Peterková, Eva (referee) ; Štroner, Marek (advisor)
This thesis is focused on the process of making a disposition draft of a small machineshop producing 70000 bearing housings per year. Theoretical part of this thesis is focused on fundamentals of designing machining production units. Practical part describes in detail the process of designing dispositional solution for the machineshop which is based on performed capacity calculations. These calculations were used as a guide in the process of designing two diferent machineshops. The first one is fitted with conventional machining devices whereas the second machineshop uses CNC mills to produce the housing. These two projects are compared to each other to give reader a better picture on which machineshop of the two is better.

Influence of the metallurgical quality of the aluminum alloy melt on the properties of investment castings
 Urban, Antonín ; Krutiš, Vladimír (referee) ; Kaňa, Václav (advisor)
The thesis focuses on the influence of shell temperature, wall thickness, and metallurgical treatment of the melt on the mechanical properties and structure of the AlSi10Mg aluminum alloy processed using the investment casting technique. The experimental part was conducted in the school foundry. Prior to the experiment, a series of simulations were performed to verify the feasibility of the experiment. The thesis describes the experimental design and conditions under which the experiment was conducted. Furthermore, it presents the evaluation of mechanical properties based on wall thickness, shell temperature, and modification. In the conclusion of the thesis, the effect of strontium modification is assessed with respect to wall thickness and shell temperature during casting, using micrographs from metallographic samples.
