Machining of quenched steels
Kosmák, Jaroslav ; Zemčík, Oskar (referee) ; Chladil, Josef (advisor)
Diploma thesis deals with machining of hardened steels. In the introductory section it is described the physical process of cutting and basic used technologies of machining. The next chapter provides an overview of cutting materials. Other chapters deal with the workpiece material and heat treatment. Furthermore, there is made a comparison of the cutting conditions while machining of hardened steels by tools from selected manufacturers. As the conclusion there is the economic evaluation.

Optimization of the production process of a precision machined part
Kolomý, Štěpán ; Sedlák, Josef (referee) ; Píška, Miroslav (advisor)
This master‘s thesis deals with optimization of cutting conditions when machining of precise parts in mass production. In experimental part of this thesis is a comparison of the roughing tool with indexable cutting inserts with the new implemented milling cutter. Tool wear of both roughing tools has been analysed. The surface roughness analysis after machining with the face milling cutter was performed. The output of this work is to obtain optimal cutting conditions to gain a minimum surface roughness.

Technology of a selected part of the vacuum pump
Lišková, Tereza ; Kučera, Lukáš (referee) ; Chladil, Josef (advisor)
The content of study is related to reducing the production times of milling of aluminum component of vacuum pump. The primary aim of the thesis is to experimentally verify the proposed cutting conditions when milling the rotor blades and then evaluate them according to predetermined parameters. The output is reducing machining time with respect to cost, tools and machine.

Machining of hard-to-machine materials by turning
Švorc, Josef ; Fiala, Zdeněk (referee) ; Píška, Miroslav (advisor)
The thesis is focused on machining of hard-to-machine materials. In the theoretical part hard-to-machine materials are divided and characterized. Furthermore, the thesis specifies hardened steels and their heat treatment, machinability and mechanism of wear and chip formation. There are tool materials and their classes suitable for machining hardened steels. The practical part deals with the influence of the cutting conditions on the roughness of the machined surface when turning hardened steel.
