    摘要:Abrasive flow machining (AFM) is a non-traditional finishing process by using the semi-solid abrasive media as a finishing tool, and usually applied to finish fine, complex components in manufacturing industries. In AFM process, the final surface quality and finishing efficiency are crucial finishing properties which have drawn wide attention and are always affected by initial surface texture of the workpiece. In the present research, the flow direction of abrasive media is determined according to the calculation of surface anisotropy ratio S-tr and texture direction S-td of the initial surface texture by using the autocorrelation function, and selection of particle size is given after calculation of the spatial frequency of the initial surface texture using a fast Fourier transform. It was found that the flow direction of abrasive media should be perpendicular to the oriented surface texture, and the particle size in abrasive media has a strong relationship to the first harmonic frequency f(1) of surface texture. Finally, the above approach was employed to the surface finish analysis of an aero-engine blade, and its efficiency was verified in the improvement of finishing properties.
