dc.description.abstract本研究係利用電泳沉積法(Electrophoretic Deposition Method, EPD Method)來實現表面鏡面拋光,藉由電泳沉積特性,拋光磨輪會不斷地再生,工件表面因此可得到相當良好的拋光結果,並可應用於改善傳統拋光製程之耗費人力、拋光效率低落及表面品質不佳等問題。本研究之EPD拋光實驗單因子參數包括有拋光時間、磨輪施加於工件表面之軸向荷重、磨輪轉速、拋光進給速率及工作電壓等,並運用電泳沉積現象和機械拋光之特性,針對不鏽鋼材質之車削面及放電面二種工件,進行表面拋光加工實驗,對其作表面粗糙度量測與表面形貌觀察,並對實驗結果進行分析與探討。 由實驗結果得知,使用SiC粒徑顆粒大小為0.9~1.5μm,進行車削面試片EPD拋光加工實驗後,可將原始表面粗糙度值為Ra 0.5 μm(Rmax 3.7 μm)的車削面,下降至表面粗糙度值為Ra 0.03 μm (Rmax 0.29 μm)的鏡面,且粗糙度改善率可達Ra 94 %及Rmax 92.2 %;另在放電面試片EPD拋光實驗後,則可將原始表面粗糙度值為Ra 1.67 μm(Rmax 10.11 μm),下降至表面粗糙度值為Ra 0.05 μm(Rmax 0.34 μm)的鏡面,且粗糙度改善率可達Ra 97 %及Rmax 96.6 %。zh_TW
dc.description.abstractIn this study, a mirror-like surface polishing is accomplished by electrophoretic deposition (EPD) method. When abrasive grains are ablated from polishing wheels, the abrasive grains in the electrolyte are moved again into the micro holes of the non-woven fabric to regenerate the polishing wheels by using the characteristics of EPD. The polishing wheel can be continuously refreshed and improves the surface roughness of the specimen markedly in a short period. The control parameters of the EPD polishing process include the polishing time, the axial loading, the rate of rotation of the polishing wheel, the polishing feed rate and the working voltage, etc. After polishing the turning machined surface and electro-discharge machined surface of stainless steel specimen, the surface of specimen were measured and observed. Moreover, the experimental results were also analyzed and discussed . SiC particles of size 0.9–1.5μm were used in this study. After turning machined surface polishing, the initial roughness of surface could be improved from 0.5 μm Ra (3.7 μm Rmax )to 0.03 μm Ra(0.29 μm Rmax ). The roughness improvement rate could be reached Ra 94 % and Rmax 92.2 %. After electro-discharge machined surface polishing, the initial roughness of surface could be improved from 1.67μm Ra(10.11 μm Rmax ) to 0.05μm Ra (0.34 μm Rmax ). The roughness improvement rate could be reached Ra 97 % and Rmax 96.6 %.en_US
