N2 - Ti-6Al-4V alloy is widespread applied in aero-engine components, such as blisk and blades. The surface quality of these components has a remarkable impact on aero-engine in aerodynamic performance and service life. Residual stress and surface roughness are considered as the most representative parameters for evaluating the surface quality. Therefore, in order to analyze the effect of grinding parameters on surface quality and improve the surface quality of components, the grinding parameters, including wheel rotational speed, feed rate, processing depth and abrasive size, were choose, and the influence of each parameter on surface roughness and residual stress were investigated. Besides, the grey relational grade analysis was used to analyze grinding parameters. Finally, through verifying the optimization results, the optimal processing parameters for grinding Ti-6Al-4V alloy were obtained. The results reveals that the surface quality of blade has been improved greatly (73.9% reduce in surface roughness and 26.3% increase in residual stress).
