Electroerosion wire cutting of technical ceramics
Habovštiaková, Mária ; Mouralová, Kateřina (oponent) ; Osička, Karel (vedoucí práce)
The presented diploma thesis deals with the issue of wire electrical discharge machining of SiSiC ceramics. The first part explains the principles of electrical discharge machining, describes the WEDM technology and presents the properties of the advanced ceramics. The second part consists of a detailed analysis of the cutting process of eighteen samples obtained with systematically changing process parameters. Based on the obtained results from EDX analysis, SEM electron microscopy and topography there was performed an analysis of the influence of process parameters on the cutting speed, surface roughness, kerf width and number of wire breaks with usage of the selected brass cutting wire. From the evaluated results it was possible to select a combination of parameters that ensured a stable machining process.

Design of a model for a mold for injection molding
Habovštiaková, Mária ; Strejček, Jan (oponent) ; Kalivoda, Milan (vedoucí práce)
Bachelor thesis deals with design of input parameters of production of plastic part by injection molding technology. The work includes basic knowledge of materials used in injection molding, the analysis of this technology itself and information about other methods of plastic production. The next part of thesis starts with the choice of specific material, compoment’s running system and the calculation of the basic technological parameters, which related to injection molding machine’s choice. The final part deals with the assessment of the component functionality and the economic evaluation of the production.
