Solution technology of part from three-phase alternator
Pokladník, Robert ; Zouhar, Jan (referee) ; Kalivoda, Milan (advisor)
This Diploma thesis deals with design technology of alternator claw pole. The technology is designed to achieve low production costs. The purpose is to prevent the transfer of manufacturing contract to countries with cheap manpower and low production costs. Technology design is done by selecting billets to the processing and economic evaluation. The dominant technology is a cutting operation that is performed on numerically controlled machines.

Influence of coatings on durability of cutting inserts during longitudinal turning
Balíček, Martin ; Sámelová, Vendula (referee) ; Jaroš, Aleš (advisor)
This thesis deals with the influence of deposited coatings for durability and tool wear during longitudinal turning of steel CSN 41 1600 (E335) and influence of wear and surface quality. The theoretical part is focused on characteristics of turning technology, application, manufacturing and methods of coating cemented carbide and tool wear. The experimental part of the thesis includes the evaluation of the measured values, a description of the material, used tools and machine tool. The values measured in the experiment imply that the most suitable of the tested tool inserts is WNMG 3-1-NF with applied coating TiAlN + TiN. Surface quality decreases with increasing wear of the tool.

Programming CNC machines with digital control system Fanuc.
Tkáčová, Alena ; Sedlák, Josef (referee) ; Kalivoda, Milan (advisor)
The theme of this bachelor thesis focuses on the CNC-programming, which is currently used in many branches of the machine industry. The theme is elaborated and divided into well-arranged chapters. The first part deals with the development of the control system of cutting machines, beginning with the hard automatization and ending with the computer-controlled cutting machines. In the second part there is described the general control system Fanuc including the machine description. The third part contains the application of the real cutting procedure - with the NC program for turning and milling of the sample component in a certain company.

Testing of cutting parameters for UMCo50 machining
Jakubec, Thomas ; Kolomý, Štěpán (referee) ; Zemčík, Oskar (advisor)
The diploma thesis deals with the machinability of materials, the theoretical part describes the factors that have a dominant influence on machinability. The basic aspects according to which the machinability of the material and the wear of the tool are determined are also given here. The distribution of cobalt alloys is given here, including the UMCo-50 alloy, which is the subject of experimental research. It is an alloy for high-temperature use with good abrasion resistance and is used especially where other materials lose their mechanical properties due to the high temperature. The practical part followed the thesis of my colleague Ing. Peter Prno [1], which due to lack of time could not measure all the necessary quantities, resp. course of back wear for the remaining two cutting speeds. During the experiment, the wear of the tool back was monitored as a function of time at different cutting speeds in turning technology. The main goal was to determine the resulting tool life at the remaining cutting speeds and thus obtain a more accurate Taylor dependence. The turning forces, the quality of the machined surface and the formation of chips were also monitored during turning.
