Abstract Aiming at the problem of cutting force and surface integrity in cutting Ti6Al4V titanium alloy, the influence of cutting parameters on machining quality is revealed by orthogonal cutting test combined with multi-parameter dynamic analysis ( cutting speed, feed speed, cutting depth ). It is found that cutting force is positively correlated with feed speed and cutting depth, but negatively correlated with cutting speed. The surface roughness ( Ra / Rz ) is mainly dominated by the feed rate, and the Ra value can be reduced to less than 0.4μm by optimizing the parameters. The distribution of surface residual stress is consistent with the trend of cutting force, and high cutting speed can reduce surface defects. The research results provide a basis for parameter optimization for precision machining of titanium alloy parts in aerospace field, and have practical guiding significance for reducing processing energy consumption and improving surface quality.
