High speed machining (HSM) generally refers to end milling at reasonable speeds and high surface feed rates. For example, in the special milling of the partial groove of the aluminum aircraft frame, the material removal rate is high, and this processing is high-speed machining. Over the past 60 years, high-speed machining has been applied to a wide range of metal and non-metal workpiece materials, including those requiring parts with a specific surface topology and materials with a hardness of 50 HRC or more. machining.
