Oct 09, 2006 In high speed machining of aluminum, by contrast, a major challenge is the tendency of the soft material to adhere to the cutting edge. The die/mold high speed machining end mill may use a coating that acts as a thermal barrier. However, if the end mill for aluminum uses a coating at all, it is likely to use one chosen more for its lubricity ...
Milling machines are also able to be computer controlled, in which case they are referred to as a computer numerical control (CNC) milling machine. CNC milling machines move the workpiece and cutter based on commands that are preprogrammed and offer very high precision. The programs that are written are often called Gcodes or NCcodes.
