The nickel-based super heat resisting alloys including Inconel 718 are used for the part of aircraft engine and gas turbine due to their corrosion resistance and the excellent mechanical properties at high temperature. However, these materials are well-known difficult-to-cut materials. Because the usage of the heat-resistant alloy increases in aircraft industry and energy industry, effective cutting technologies are demanded. We propose innovative machining technologies for these metals by using small size ball-nosed end mills under condition of high speed rotating and high speed feed rate. In this paper, we wish to report on the results of high speed milling for nickel-based super heat resisting alloys.
