Simulation Study on High-Speed Milling Performance of Rail U71Mn Material

The high-speed milling of rail is one of the important directions in the development of rail maintenance technology. In order to study the high-speed milling performance of rail material, the U71Mn material milling simulation model was established using metal cutting simulation software AdvantEdge to analyze the changing rule of cutting force and cutting temperature during milling. Results show that the cutting force decreased with the increase of the milling speed of the rail, and the cutting force decreased with the cutting speed of 1200 r/min. The cutting heat increased significantly with the cutting speed, and the heat is mainly taken away by the chips, and the temperature rise is small. The research results to achieve high-speed rail milling have important guiding significance.
