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.

Machining of the cobalt alloy UmCo50
Prno, Peter ; Sedlák, Josef (referee) ; Zemčík, Oskar (advisor)
The diploma thesis deals with the topic of machinability of materials. The theoretical part describes the aspects according to which machinability can be evaluated. The material side of the thesis is focused on various types of difficult-to-machine materials. The cobalt alloy UmCo50 belongs to the group of difficult-to-machine materials and it is the subject of the experimental part. UmCo50 is an alloy for high temperature use. The primary aim of the thesis was to monitor the wear of the selected cutting tool when turning this alloy. Other aspects of the selected machining process were also monitored, such as force effects or the quality of the machined surface. Despite the fact that machinability of tested materials cannot be expressed in terms of the absolute value of a quantity, it is necessary to compare the various aspects of the machining processes by reference materials. However, certain conditions of this comparison must be met. Based on this, a comparison of tested and reference material was performed.
