Comparison of options in production of injection molds
Marko, Tibor ; Sliwková, Petra (referee) ; Kandus, Bohumil (advisor)
The project elaborated in frame of engineering studies branch engineering technology (2303R002) by comparing different methods of injection molding tool manufacturing. Set manufacturing method for each one of three selected plastic parts, particularly focused on cavity and core manufacturing. Various technological methods of manufacturing, material removal and forming plastic parts will be used for each cavity and core. Production research and economical evaluation will be developed based on given production processes and technology, which will determined which technology to use to pay off in economic terms, depending on the complexity of the plastic part.

On the modern technologies of hole production in metal materials
Laňka, Lubomír ; Sliwková, Petra (referee) ; Píška, Miroslav (advisor)
This bachelor thesis is focused on the modern technologies for the hole production in metal materials. In the first part the fundamental technologies are described including how to make the hole or to modify it. The second part deals with the modern cutting tools, and the other part includes some machines for hole production. Some non-conventional methods of hole machining are also mentioned. The last two parts deals with the experiments - the tool wear and other phenomena are evaluated when machining some selected materials. The work confirms that the titanium alloy is a material very difficult to drill up today.

High Speed Steels Cutting Tools and their Applications Today
Nosek, Jan ; Dvořák, Jaromír (referee) ; Sliwková, Petra (advisor)
My bachelor’s thesis “High speed steels cutting tools and their applications today” is about a chemical concept, a heat processing, a cutting property and a production of cutting tools of high speed steel materials. This work consist a possibility of an increase performance, a resist of high temperatures and a durability of high speed steel tools by means of PVD films and an accessible technologies. Next I must found producers of cutting tools and their production of high speed steels.

High-Speed Steel Drills and their Uses
Jaroš, Aleš ; Dvořák, Jaromír (referee) ; Sliwková, Petra (advisor)
This Bachelor thesis, as one can deduct from the title, deals with high-speed steel drills and their uses into practice. The problem of high-speed steel is described step by step from division, chemist to heat treatment. Fundamental features of drilling method and tools that are suitable for drilling are described either. The last part of Bachelor thesis is focused on producers and application of high-speed steel drills to practice.
