本研究主要是探討膠體磁力研磨(Gel Magnetic Abrasive Finishing)對於平面研拋加工之效能評比,以模具鋼(SKD-11)為實驗試片,進行平面研磨加工。配合自製之磁性NC刀把,安裝於CNC综合加工機主軸上,將導磁性高分子膠體磨料吸附於磁性NC刀把加工端,以磁力線與高分子膠體的作用,將磨粒拘束並提供撓性加工之特性。運用田口法與單因子實驗法,來探討膠體磁力研磨對於平面研磨之加工效能。
藉由主軸轉速、進給速率、加工路徑、路徑間隙、磁力距離、磁鐵種類、磨料粒徑與膠體硬度等加工參數,來觀察試片加工後表面粗糙度改善,與各加工因子對於研拋效能之影響。經田口法實驗結果,在加工三十分鐘後表面粗糙度改善率可達到88%。最後經由單因子實驗結果,其表面粗糙度可由Ra 0.26 降至Ra 0.018 ,其表面粗糙度改善率可達到93%,因此證實了膠體磁力研磨對於平面研拋加工上具有優異的研拋效能。
This research is mainly to probe into gel magnetic abrasive finishing and grind and throw the efficiency processed to compare and assess to the level. Regard SKD-11 as the experiment to try slice, grind and process the level. Cooperate with the magnetic NC handle of a knife made by oneself installation is on the processing machine main shaft of CNC. Lead magnetic high polymer colloid abrasive absorb on handle of a knife, NC of magnetic, processing ending. Magnetic force line and function, high polymer of colloid, make grit constrained offering the characteristic that the flexibility is processed. Use Taguchi Method Overview and Single gene experience, to probe into the magnetic force of the colloid and grind the processing efficiency ground to the level.
Process the parameter in rotational speed that by the main shaft, entering to the speed, processing a foot-path of route, route interval, magnetic force distance, magnet kind, abrasive and hardness of colloid. The roughness of surface is improved after observing and trying a slice of processing, for grinding the influence of throwing efficiency with every processing factor. Through Taguchi Method Overview experimental result, surface roughness improving rate can be up to 88% after processing one minute. The experimental result of Single gene experience, can know the roughness of surface is reduced from 0.26 to 0.018 finally, so the improving rate of roughness of surface can be up to 93%. So there is excellent grinding the efficiency of leaving behind to prove the effect of plane polishing in gel magnetic.
