Productive milling of aluminum alloys
Dvořák, Jakub ; Žídek, Jan (referee) ; Jaroš, Aleš (advisor)
This bachelor thesis is focused on milling of aluminum alloys, where the technology of milling is described in the first place, then the cutting materials and aluminum alloys. The main subject of the work was to carry out the experiment. The Experiment was focused on influence of cutting conditions on the final quality of the surface with regard to machine time. The aluminum workpiece was milled at different cutting speeds and various feed per tooth. At the same time the quality of the surface was examened and machine times were calculated. The Experiment showed us, whether it pays to use higher cutting speeds and feed per tooth, keeping the set of limited values of surface roughness with respect to the machine time. The result of the experiment is the following - the increasing feed per tooth deteriorates the quality of machined surface, but machine time is reduced.
