　　本研究設計單邊磁極模組之磁性研磨裝置，此磁極所吸附之鐵粉會隨著磁力線排列成臥式磁刷。使用此磁極模組對Al 6061鋁合金進行磁性研磨。在靜態與動態下，探討磁刷成型方式、鐵粉量、負荷對鐵粉與工件的接觸面積之影響。另探討乾式與濕式磁刷(水性切削液或煤油)，以及循環水性切削液混合氧化鋁磨粒(定點或往復加工)，對鋁合金工件的表面粗糙度之影響。並利用光學顯微鏡觀察鋁合金工件以及磁刷的表面，以選擇最適合磁性研磨鋁合金之方式。
在靜態實驗得知，當磁刷為自然成型時，接觸面積隨負荷增加而變大；當磁刷為事先定型時，接觸面積與負荷無關，而為一定值。在動態實驗得知，當磁刷為事先定型時，接觸面積隨著鐵粉量或負荷增加而變大。
在使用乾式磁刷加工的實驗得知，當加工負荷較小時，鐵顆粒鑲嵌於工件表面的情況越少。另外，不論濕式磁刷為水性切削液或煤油，加工後之工件表面皆有黏附磨耗，且發現有鋁屑填塞於磁刷上。
　　在循環水性切削液混合氧化鋁磨粒進行定點加工的實驗得知，在加工時間5分鐘時出現鐵顆粒鑲嵌於工件表面的情況，且磁刷表面已有鋁屑填塞。在往復加工的實驗得知，於含有1 μm氧化鋁磨粒的加工液中，使用負荷0.1 N加工8分鐘後，鋁合金工件的表面粗糙度從Ra = 0.197 µm、Rmax = 1.603 µm下降至Ra = 0.089 µm、Rmax = 0.947 µm。

　　This study designs a magnetic abrasive finishing device with a one-sided magnetic pole module, and iron powders adsorbed by the magnetic pole are arranged into a horizontal magnetic brush along with the magnetic lines of force. The 6061 aluminum alloy is finished using this module. Under the static and dynamic conditions, the effects of the magnetic brush forming method, the amount of iron powder and the load on the contact area between the iron powder and the workpiece is discussed. In addition, the effects of dry and wet magnetic brushes (aqueous cutting fluid or kerosene), and circulating cutting fluid mixed alumina abrasive grains (fixed-point or reciprocating finishing) on the surface roughness of aluminum alloy workpieces are investigated. The surface of the aluminum alloy workpiece and the magnetic brush are observed using an optical microscope to choose the most suitable method for magnetically grinding the aluminum alloy.
　　In the static experiments, when the magnetic brush is naturally formed, the contact area increases with increasing load. When the magnetic brush is pre-shaped, the contact area achieves a constant value and independent of the load. In the dynamic experiments, when the magnetic brush is pre-shaped, the contact area increases along with the amount of iron powder and load.
　　In the finishing experiments using the dry magnetic brush, when the load is small, the less the iron particles are embedded on the surface of the workpiece. In addition, regardless of whether the wet magnetic brush is an aqueous cutting fluid or kerosene, the adhesion wear can be observed on the surface of the workpiece after finishing, and aluminum scrap is embedded on the magnetic brush.
　　In the fixed-point finishing experiments using circulating cutting fluid mixed alumina abrasive grains, iron particles were embedded on the surface of the workpiece at a finishing time of 5 minutes, and the surface of the magnetic brush was filled with aluminum chips. In the reciprocating finishing experiments using a fluid containing 1 μm alumina abrasive with a load of 0.1 N, the surface roughness of the aluminum alloy workpiece decreases from Ra = 0.197 μm, Rmax = 1.603 μm to Ra = 0.089 μm, and Rmax = 0.947 μm at a finishing time of 8 minutes.
