Analysis of chip forming mechanism with a high-speed digital camera
Tichý, Vojtěch ; Sliwková, Petra (referee) ; Polzer, Aleš (advisor)
This thesis covers matters related to high-speed digital cameras and their usage in various spheres of human activities, mainly in research of chip forming. Thesis summarises important knowledge needed for creation of high-speed recordings and choice of suitable lenses. Focus is taken on creation of high-speed recordings of chip forming process in turning operation outside grooving by using of different types of chipformers. Main goal is to verify its functionality in specific value range of feed per revolution.

The Analysis of Carbide Cutting Inserts.
Pavelka, Rudolf ; Humár, Anton (referee) ; Osička, Karel (advisor)
This study states basic technological aspects of metal machining with cutting inserts, with special stress on coated carbide cutting inserts. Among others, it states wear-out theory incl. wear-out accompaniments, problems of chip-forming and other factors of metal machining. At the end of the study, it contents a description of the latest cutting materials and construction elements of cutting inserts from reputable producers and, for some of them, also the course and the results of practical tests and comparison.

Analysis of the coated carbide cutting inserts
Zdráhala, Radim ; Kolář, Ladislav (referee) ; Fiala, Zdeněk (advisor)
Bachelor thesis is focused on the analysis of the cutting and specific cutting forces during face milling of coated and uncoated exchangeable cutting inserts (VBD). The theoretical part deals with the characteristic of the milling process, coating of cemented carbides and last but not least deals with methods for measuring cutting forces. The experiment is described in the experimental part that also includes evaluation of load forces coated and uncoated exchangeable cutting inserts during changes in cutting conditions. Finally is performed the comparison of values coated and uncoated VBD for flank wears and load cells.

Modern surface coating of cutting tools for machining
Tříletý, Vlastimil ; Ohnišťová, Petra (referee) ; Píška, Miroslav (advisor)
This bachelor thesis consists of two main parts. The theoretical part generally describes methods for coating cutting tools, wear mechanisms of cutting tools and experimental evaluation of coating properties and evaluation of tool life. The practical part is focused on the evaluation of tool life based on the observation of the development of wear using a scanning electron microscope.
