Technology assembling of a part "cage" in a company CCI
Tkáčová, Alena ; Sedlák, Josef (referee) ; Kalivoda, Milan (advisor)
This thesis is focused on techology of manufacturing a "cage" component at CCI Brno company. It solves drilling holes to the outside diameter of it. In the first part the company CCI is introduced, and in the second part is focused on component and material analysis. Next step is analyzing present manufacturing procedures and proposing its change. At the end of this thesis is techno-economic comparison of the present and proposed technological change.
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.
Machining of difficult machinable materials
Perončík, Martin ; Novák, Zdeněk (referee) ; Humár, Anton (advisor)
Diploma thesis is specialized to solving of problems machining of diffi-cult machinable materials. There is carried out the analysis of difficult machinable materials in term of chemical composition, physical and mechanical properties. In the following it deals with analysis of machining, specification of geometry, material of cutting tools and cutting conditions.
Cutting ceramics and its effective use
Podešva, Lukáš ; Dvořáková, Jana (referee) ; Humár, Anton (advisor)
In the first part of this diploma thesis there are discribed basic findings about cutting ceramics (sorts, notation, structure, physical-mechanical properties, using, production) and it evaluates this tool material from the aspect of cutting power. The second part focuses on complex data processing about assortment of ceramics cutting materials of significant tool materials producers and comparison of service conditions (kind of mechanided materials, cutting conditions), which are recommend for effective turning by producers.
Superhard cutting materials and theirs effective use
Grausgruber, Jiří ; Prokop, Jaroslav (referee) ; Humár, Anton (advisor)
n the first part of this diploma thesis there are described basic findings about superhard cutting materials (sorts, notation, structure, physical-mechanical properties, usage, production) and evaluates this tool of material from the aspect of cutting ability. The second part focused on complex data processing about assortment of superhard cutting materials of significant tools materials producers and comparison of work conditions (kind of machined ma-terials, cutting conditions), which are recommend for effective turning applica-tions by producers.
Cutting ceramics and its effective use
Heča, Jan ; Prokop, Jaroslav (referee) ; Humár, Anton (advisor)
Thesis dealing with cutting ceramics and its efficient use. Introduction describes the general characteristics of the cutting of ceramics, its history and development and production of various kinds. This section describes the mechanical and physical properties with potential application in machining. The se-cond part is an overview of cutting-frame in the range of selected world leaders. Ano-ther section focuses on general assessment of the power of cutting tools and other ma-terials comparison. The fourth part, is comparing the working conditions of producers and tools intended for cutting.
Optimization of grinding characteristics when grinding cemented carbides by diamond wheels
Mangl, Petr ; Dvořák, Jaromír (referee) ; Humár, Anton (advisor)
This master‘s thesis is presenting the way of the optimization of grinding characteristics when grinding cemented carbides by diamond wheels. There is described the theory of grinding, including grinding wheels and basic characteristics of cemented carbides in the theoretical part. There are defined experimental metering accomplished on the CNC grinding machine Walter Helitronic Power Mini in the practical part. There were tested eight grinding wheels. The grinding rate, surface roughness Ra, theoretic guaranteed storage period of grinding wheel in number of cuts, theoretical capacity of machined material, achievement of grinding machine and behaviour of the wheels when grinding ware evaluated from the reached results.

Machining of Ni80TiAl alloy detail
Kudrna, Miloš ; Novák, Zdeněk (referee) ; Humár, Anton (advisor)
The master`s thesis deal with analysis of machining technology of the bolt from the superalloy Ni80TiAl for the company Sanborn a.s. The aim of the thesis is the project of new technology by usage of new tool, indexable inserts and cutting conditions. The results are speedup of the roughing operation, reduction of the manufacturing cost and the product price.
Superhard cutting materials and theirs effective use
Stradějová, Alena ; Madaj, Martin (referee) ; Humár, Anton (advisor)
The master’s thesis is aimed at superhard cutting materials (polycrystalline diamond and polycrystalline cubic boron nitride) and their effective utilization. It describes the characteristics and production of these materials and evaluates product ranges of the most significant producers of tools and tool materials in given area. It further compares working conditions of selected world's producers which are related to the growing utilization of these materials in machining process. The thesis also deals with the cutting power of tools and provides a technical-economic assessment of the discussed issue.
