TA7 titanium alloy has good thermal stability and oxidation resistance at high temperature,so it has broad prospects in aviation,aerospace,ships,cryogenic engineering and other fields.However,its high strength and low thermal conductivity make it a typical difficult-to-machine material.The titanium alloy TA7 milling experiment was carried out to study the influence of cutting data on the cutting characteristics of TAN.Based on MINITAB,the regression models of cutting force,surface roughness and cutting data were established,and the response relationship between cutting force,surface roughness,residual stress and cutting data was analyzed.The influence of cutting data on cutting force time domain and frequency domain signal,machined surface morphology and residual stress is revealed.
