| 摘要(中) |
本研究是以磨料流動加工方法而利用螺桿試件旋轉來驅動黏彈
性磨料，再進行對其試件表面的研磨拋光。實驗中，藉由控制加工時
間、磨料粒徑、磨料濃度、主軸轉速等加工參數，探討對磨料黏度、
表面粗糙度的影響，並找出最佳參數組合；同時亦觀察實驗後，各加
工參數對工件表面形貌之影響。
由實驗結果顯示，隨著加工時間的增加，磨料會呈現良好的流動
性，此特性有利於螺旋研拋，使達成理想之表面研拋效果。而在選用
微細磨粒與高濃度之磨料，配合適當的主軸轉速，可獲得最佳表面改
善效果，有效地將工件之表面粗糙度由0.46μmRa 降至0.13μmRa，
表面有微量的材料去除，而達到快速研拋效果。 |
| 摘要(英) |
The study presents the polishing of screw surface by abrasive flow
machining, which is propelled by itself. In the experiment, the effects
upon working temperature, abrasive viscosity and surface roughness are
discussed by controlling machining time, particle size, abrasive
concentration and the rotation speed of spindle. Also, the influence of
these parameters on the polished surface is observed. Thus, the best
parameter setting could be obtained.
The result of the experiment shows that the liquidity of abrasive
would rise with the increasing of machining time. This property is
beneficial for fine spiral polishing to achieve an ideal polishing effect.
The better polishing effect could be obtained by using 4μm particle size,
50% of abrasive concentration,5 minutes machining time and 2500 rpm
of rotation speed. The surface roughness can be effectively reduced from
Ra 0.46μm to Ra 0.13μm. |
