In order to solve the problems of large cutting force and high cutting temperature when milling titanium alloy materials with four-flute flat-end milling cutters,AdvantEdge FEM simulation software is used to simulate and analyze the milling of four-flute flat-end milling cutters.The tool parameters are optimized in the direction,and the best tool parameters are used in the simulation of cutting parameters to obtain the best cutting parameters for milling Ti-6Al-4V materials,and verification test is carried out.The research shows that based on the tool stress distribution and chip curling state,the optimal tool parameters are obtained,the minimum cutting force parameters and the minimum cutting temperature parameters are obtained by the milling simulation of different cutting parameters,and the effectiveness of the simulation is verified by experiments,which provides valuable theoretical reference for high efficiency milling Ti-6Al-4V material.
