Original abstract
This paper deals with a new roughing milling cutter design made of high-speed steel by precision casting technology. Each edge of the innovated milling cutter has two special flutes that make so-called compensation edges which help to reduce tensile stress in the end of cutting teeth. Three kinds of PVD coatings ((Al,Ti)N, (Al,Ti,Cr)N and nanocomposite nACo) were used to preserve the tool life. The coatings were made with a cathodic-arc deposition process. Machining tests were carried out on the vertical milling machine FB 32V. Cutting conditions were constant and standard carbon steel C45 DIN EN ISO 4957 (W.Nr. 1.1191) was used as workpiece material. Monitored parameters were force loading and flank wear measured with Stemi 2000 Zeiss. Dynamometer Kistler 9575B/SW DynoWare were used for measuring of instantaneous force loading in long time series. The results confirm a good cutting performance of the new tool.
