AMS6260 is one of the materials specified in the U.S. Aerospace Materials Standard, which is mainly composed of Fe and contains Ni, Cr, and Mo. It is used as a material for parts that require high toughness, such as gears of aircraft engines and large parts of aircraft. Although the heat treatment hardenability and high toughness have been shown to be advantages of AMS6260, there are few research examples. In this study, we focused on the heat treatment hardenability of AMS6260, and AMS6260 after the heat treatment process is cur using a radius end mill on a NC milling machine under some cutting conditions. The tool life after cutting was evaluated from the images of flank wear taken by a microscope, and the surface roughness of the bottom surface of the machined part was measured. As a result, the cutting characteristics of AMS6260 using the radius end mill was clarified.
