Coating methods for cutting tools
Tuna, Jaroslav ; Prokop, Jaroslav (referee) ; Humár, Anton (advisor)
This diploma thesis is aimed on methods of the coating cutting material (cemented carbide, cermets, cutting ceramic, super hard materials) and evalutation individual method regarding technological posibilities of deposition of hard coatings a their mechanical, thermal and che-mical properties. The task of the work is full elaboration obtained technical knowledges and mainly evalutation a comparison of the work conditions (kind of the cutting materials, cutting conditions) that selected producers recomended for effective turning aplications of the coa-tings cutting materials.

Modern cutting tools for grooving and cutting-off
Axmanová, Hana ; Humár, Anton (referee) ; Píška, Miroslav (advisor)
The presented diploma thesis is divided into two parts. The theoretical part deals with modern catting tools for grooving and cutting-off, choice of material of catting inserts, and with types of tool wear and their classification. The second part of the thesis deals with calculation of volumetric wear of catting tool for grooving. There was measured the power load of the new and worn tool in the experimental part and the observed data were evaluated by software. The graphs of power load and volumetric wear of tool were created.

Micro-turning applications in high precision manufacturing performed by diamond tools
Švorc, Josef ; Dvořák, Jaromír (referee) ; Žídek, Jan (advisor)
Bachelor thesis is focused on micro-turning. The work takes the form of a literary research, which aims to make an overview of the production technology. First, it deals with the definition of the topic itself and with the physical properties and phenomena that occur during micro-machining. Then it discusses the construction of micro lathes and their division into categories and compares them to each other. It also deals with the cutting tools suitable for this machining process and their production and shaping. The last part of the thesis is focused on the application and utilization of micro-turning in industry and on the creation of non-rotational components and micro-structures.
