High-speed Machining of Bearings from Material 100Cr6
Tropp, Pavel ; Osička, Karel (referee) ; Sedlák, Josef (advisor)
This Master's thesis deals with the issue of high-speed turning of the 100Cr6 material. The aim is to identify and experimentally validate an innovative production process for a particular component. The thesis includes theoretical basis of high-speed machining, analysis of the current state of the manufacturing process, innovation design and experimental verification. At the end of the thesis, parameters of the machined surfaces of specimens are evaluated.

Technology solution of "konzola" component in condition of a small firm
Štegnerová, Kateřina ; Slaný, Martin (referee) ; Kalivoda, Milan (advisor)
This work deals with the solution technology component of the console. There is an evaluation of technological principles, functionality and the suggestion of optimize. Stock, machines, tools and gauges for each operation are selected according to conditions of the company. For each operation are determined cutting conditions and production time. There are two versions of the production process. Additionally these two versions are evaluated. The console is also analyzed in terms of stress-strain relations, finite elements, which appear critical points. In conclusion, these results are judged.

A study of cutting forces during the turning process and their measurement
Piroš, Viktor ; Trčka, Tomáš (referee) ; Polzer, Aleš (advisor)
This bachelor’s thesis is structured as a literature search. Its target is to show a complex look at the problematics of force load in turning process. In the beginning, the thesis is focused on brief characteristics of turning process and tool geometry as a one of the main aspects influencing the force load in the machining system. Furthermore, the thesis deals with problematics of force load creation and its dependence on basic cutting parameters. Second part of the thesis is dedicated to the options of force load measurement in turning process and works out an illustrative example of numerical evaluationof measured data with basic statistical indicators in detail.

Technology of CNC production of aluminium alloy part
Novotný, Michal ; Polzer, Aleš (referee) ; Píška, Miroslav (advisor)
The diploma thesis Technology of CNC production of aluminium alloy part is based on the particular specification of the company FP cz s.r.o. The core of the work lies in the proposal of production technology of the given part made from aluminium alloy which is machined by two universal CNC lathes with operating system FANUC. There is an introduction to the issue of characteristics and machinability of aluminium and its alloys because of coherence of the thesis. Practical part is focusing on the particular proposal of production technology which consists of the casting analysis, method of clamping on the chosen machines, choice of tools and verification of the production. There can be achieved effective production and significant time reduction with proposed technology.

Machining of hardened parts
Havlík, Daniel ; Osička, Karel (referee) ; Polzer, Aleš (advisor)
This bachelor thesis is focused on the machining of hardened parts. The beginning of the work is devoted to the analysis of specific materials, 42CrMo4, 42CrMoS4 and 50CrMo4. Next described thing is heat treatment. The main part of this work consists of theoretical analysis turning of hardened parts and theoretical analysis of the thread whirling of ball screw, where the principle of ball screws is also described.
