20.500.12556/DKUM-46663 Sodobni kroglični rezkarji za izdelavo preoblikovalnih orodij Modern ball-end mills for the manufacture of deep-drawing tools Magistrsko delo sem pripravil v podjetju EMO - Orodjarna d.o.o iz Celja. Podjetje za svoje potrebe izdeluje rezkarje iz karbidne trdnine z namenskim 5-osnim brusilnim strojem. V nalogi sem se opredelil na sodobne kroglične rezkarje. Predstavljena je izdelava rezkarjev v podjetju, testiranje in primerjava rezkarjev med različnimi proizvajalci. Testiranje rezkarjev smo izvedli na Fakulteti za strojništvo v Mariboru v laboratoriju za odrezavanje. Primerjali smo rezkarje iz podjetja EMO - Orodjarna d.o.o. z rezkarji podjetij ISCAR, Sandvik Coromant in SECO TOOLS. Rezultat testiranja je bila obraba rezkarjev, obstojni čas orodja ter velikost rezalnih sil orodja na preizkušanec v smeri Fx, Fy in Fz. Dissertation was prepared in the company EMO - Orodjarna d.o.o. from Celje. The company manufactures milling tools for their own needs from tungsten carbides with their 5-axis grinding machine. My work was focused on modern ball-end mills. Presenting their manufacture in the company, testing and comparison. Testing was done on the Faculty of Mechanical Engineering in Maribor, in the Laboratory for Researches in Cutting. We have compared milling tools made in the company EMO-Orodjarna d.o.o. with milling tools from companies Iscar, Sandvik Coromant and Seco Tools. As the results of the comparison, we got data for end mill tool ware damage, tool life and the size of the cutting forces, from the tool on the workpiece in all directions Fx, Fy and Fz. rezkarji preoblikovalna orodja orodjarstvo frezala testiranje 5-osni CNC brusilni stroj primerjava milling cutter deep-draw tools toolmaking test 5-axis CNC grinding machine comparison true true false [N.
