When finishing the blisk with the process of magnetic abrasive finishing

the interference between the workpiece and the magnetic pole is serious. Machining with radial magnetic pole instead of axial magnetic pole can effectively avoid interference

but the finishing pressure and the finishing efficiency are low. By analyzing the mechanism of radial magnetic abrasive finishing and the microscopic forces carried by the single magnetic abrasive particle

it derived that increasing the variance ratio of magnetic field intensity could significantly increase the magnetic abrasive finishing efficiency. With finite element simulation and analysis

it showed that slotting rectangular grooves along the axis direction on the surface of magnetic pole could improve the variance ratio of the magnetic field intensity. Through the magnetic abrasive finishing experiment to nickel-based superalloy blisk and analyzing the experimental data

it was concluded that the magnetic abrasive finishing with radial magnetic pole as the tool can realize finishing the blisk without interference

the magnetic abrasive finishing efficiency can be increased by 31% after the slotting rectangular grooves on the magnetic pole. The surface roughness value of the blisk was reduced from 1.2μm to 0.18μm. It verified the feasibility that the magnetic abrasive finishing can realize finishing the blisk surface with high efficiency and quality.
