摘　　要：通过ANSOFT软件仿真和实验的方法,研究在磁极头表面加工出矩形槽、60°V型槽、圆环槽和分布圆孔4种不同槽型时对磁力研磨后工件表面粗糙度的影响。采用ANSOFT软件仿真磁极头表面加工出不同槽型时,工件表面的感应磁场强度分布。仿真结果表明:在磁极头表面加工出矩形槽时,工件表面感应磁场周向梯度最明显。实验结果表明,在磁极头表面加工出矩形槽时,工件表面粗糙度改善率最高为32.95%。对比不开槽和加工出矩形槽两种磁极头形式下的磁力研磨加工结果,得出采用矩形槽开槽形式时,磁力研磨的加工效率有所提升。In this paper,methods of A NSOFT simulation and experiment were used to analysis the influence of magnetic pole groove,like rectangular groove,60°V type groove,circular ring groove and uniform circular hole,on the surface roughness of workpiece after magnetic abrasive finishing(M AF).Using AN SOFT software to simulate the induction magnetic field intensity distribution on the surface of workpiece under magnetic pole with different groove shapes.Simulation results show that,an obvious induction magnetic field intensity gradient was found under rectangular groove type magnetic pole.Experimental result show that,the biggest ratio of the change in surface roughness was found under rectangular groove type magnetic pole as 32.95%.Compared the results achieved by magnetic abrasive finishing with no groove magnetic pole and rectangular groove magnetic pole,a higher machining efficiency was gained in rectangular groove magnetic pole type M AF.
