Design of ferromagnetic pole based on ANSIS and performance tests under the magnetic finishing

Magnetic finishing is a new surface finishing technique. When the ferromagneto pole is used in the magnetic finishing, a new method for finishing the surfaces automatically under the numerical control is conveniently developed. In the paper, design of the magnetic loop for magneto pole has been discussed and slotting parameter on the bottom of the pole which affect the distribution of the magnetic field has been analyzed by FEA(Finite Element Analyses).The performance tests for the slotted pole have been done on the numerical control machine tool ZJK7532A. The surface roughness of the finished workpiece have been improved very obviously comparing with the surface roughness of the finished work piece processed by the un-slotted pole.
