Abstract： Titanium alloy materials are widely used in the aerospace field due to their advantages of high strength，heatresistance， welding，etc. The titanium alloy integral blade disc blades are thin-walls， high hardness，and are prone to deformation in processing，making it dificult to ensure processing quality. Therefore，by establishing a simplified geometric model of titanium alloy blades and tools，itis introduced into the finite element software DEFORM to simulate the finishing and milling process of titanium alloy blades，and observe the dynamic miling of titanium alloy blades in real time. Through the dynamic finite element model，the milling depth and milling speed are changed， and the average milling force data at different moments are collected，and the optimal data is optimized to obtain the optimal finishing milling depth and milling speed of titanium alloy blades. Finally， the optimized milling parameters are used for actual finishing milling. Experiments show that the milling finite element simulation model can effectively predict the finishing and miling process of titanium alloy blades. The milling speed after milling is optimized is 450m/min and the milling depth is 0.15mm ， providing milling parameters and tool selection for the finishing and milling of theoveral blade disc of titanium alloy，and providing a theoretical basis for actual finishing and milling.
