摘要

為達到相當之表面光澤，不鏽鋼材料常於拋光後施以光製程序，而技術成分甚高之光製加工技術亟須甚鉅之訓練時間及成本，以田口法實驗計畫進行規劃，求出最佳光製參數組合為本文之目的。先以砂帶拋光AISI 316L不鏽鋼工件做為實驗工件，再以蔴輪轉速、光製時間、以測力計量測的按壓力量及蔴輪拋光所需的潤滑土，由四因子三水準之L9直交表進行實驗，實驗以白光干涉儀及掃描式電子顯微鏡進行結果量測，結果顯示最佳參數水準組合為：蔴輪轉數1800rpm、光製時間10次、按壓力量10N、使用綠油土潤滑，其驗證結果可使表面粗糙度由原始拋光面Ra 0.29 ± 0.06 (μm)進展到Ra 0.093 (μm)，顯示本研究所得之參數水準組合，對於蔴輪光製加工，具有具體的成效。

For enhancing the surface gloss of the AISI 316L stainless steel which is widely applied within the modern wearable devices, the buffing by sisal wheel is therefore taken behind the polishing for the previous stainless steel. The training cost of the buffing technology is heavy due to the higher technical skill. The Taguchi method is therefore used to find the operational parameters during buffing. The rotational speed of sisal wheel, time, normal force and the lubrication compound with three levels of each parameter are arranged by the L9 orthogonal table. By the experiment table, the S/N ratios and the responses of each factor are derived. Results show the optimal processing parameters was concluded to be repeatedly processed ten times by adding green abrasive and applying normal force 10 N to sisal wheel rotated at 1800 rpm. The surface roughness is enhanced from Ra0.29 ± 0.06 (μm) to Ra0.093 (μm) which made great achievement on the surface gloss.
