With the help of AdvantEdge-a software of simulation, making the 2D simulation of super alloy GH4169 milling machining. In dry cutting, with the carbide ceramic cutting tool to do single factor experiment, arranging the reasonable cutting parameters and proving relevant conclusions in the practice, which based on the influences of milling forces and Maximum temperature and pressure by the speed of main shaft and feed engagement, all above will be references to the experiments and practice in the future.
