Designing a Component Technology for the ŽĎAS Company
Ločárková, Hana ; Kubík, Roman (referee) ; Kalivoda, Milan (advisor)
The Bachelor Thesis is focusing on the manufacture of a gear ring assembled from two half-rings. In the first chapter the product itself, the gear ring and the company ZDAS, a.s. where it is made, are described. This is followed by component production sequence, starting with the receipt of purchase order, the pre-manufacturing operations, making the pattern, casting itself through the rough machined semi-product release to the finish machining workplace incl. making the teeth. In the next section the attention is paid to production-related critical points and the proposal of possible new version of technological process. The last section is devoted to the technological-and-economical assessment of the production proposed. The production is looked on in terms of satisfaction of the desired quality criteria. The production sequence is traced as per the schedule and the sequence of operations and/or workplaces involved in the manufacture is shown.

Manufacture and use of high-alloy steel castings
Koláček, David ; Kaňa, Václav (referee) ; Pernica, Vítězslav (advisor)
This thesis includes material issue-knowledge of stainless steel cast. In the first part of thesis are analysed the causes of corrosion, its impact on metal material and is explained the creation of corrosion resistance.The next part of thesis introduces separation of stainless steel based on structure and chemical composition, explains its properties and its possibilities of using in practise. The thesis also explain some production processes of the stainless steel cast. In the final part of thesis are illustrated some possibilities of using stainless steel in practise.

Casting production - Full mould technology
Lekeš, Petr ; Bořil, Petr (referee) ; Pernica, Vítězslav (advisor)
The aim of this thesis is to elaborate a complete study on the topic of production of castings by a evaporation pattern and the apply my knowledge I gained from completing this thesis and make my own cast. Based on the assigment the thesis is devided into two parts, where the first part is focused on the problems of production by this technology, from creating the evaporable pattern, through modern technologies used for this method of casting, to possible defects in the cast, which are connected with this method. In the second part is described the process of making the experimental cast. The result of this work was the familiarization with this unconventional method of casting and the evaluation of its application in today’s foundry industry, as a full-value alternative for common casting technologies.
