On the advanced production technology of UHMWPE joint implant part
Urbancová, Kateřina ; Sliwková, Petra (referee) ; Píška, Miroslav (advisor)
This bachelor’s thesis is dealing with the problematics of individual joint replacements. The thesis summarizes the modern materials used for making artificial joint replacements, but it concentrates mainly on the plastic femoro-tibial part of the implant, usually manufactured from ultra-high molecular weight polyethylene. This material is the best choice when manufacturing the articulating surface of the joint replacement at the moment. The thesis pays attention to the polyethylene surface treatment, as the quality of the surface affects the wear of the plastic, which is critical for the implant lifespan. The thesis also focuses on analysis of the coefficient of friction of UHMWPE in contact with the titanium femoral component. Another part of this thesis is also a wear analysis of used tibial inserts made of UHMWPE and the mechanisms of wear.

Analysis of modern milling technologies for shaped parts
Pavelek, Michal ; Kalivoda, Milan (referee) ; Zemčík, Oskar (advisor)
The aim of my bachelor thesis is the analysis of modern milling technologies for shaped parts. The work offers the categorization and definition of shaped parts, and a description of the characteristics of milling techniques and methods used in the production of shaped parts. The work also describes the machines and tools used in the process of milling shaped parts. The last part of the paper offers the evaluation of each analyzed method, their comparing, and points out both their advantages and disadvantages.
