    Abstract: 本研究對玻璃表面進行二維振動輔助磁粒研磨的加工方法。有別於使用化學方法對表面加工,此研究使用物理方式加工,使表面擁有加工紋理,用來改善表面疏水特性,並針對油污沾附結果討論。
    ;The research is focused on glass machined by magnetic grinding with vibration assisted. The target is to change the texture of glass by physical method. This method is different from chemical method such as spraying and coating. The way making glass’s surface with texture is intended to improve glass’s hydrophobicity and stain resistance.
    Research is separated in to two parts. The former parts is to analysis whether glass can be machined or not. Therefore, the parameter of removal weight is used as a standard, the heavier the better. Variation of parameters included machine gap, machine time and concentration of solution. Through the research the best machine gap is 0.1mm. The best machine time is 20min. The best concentration is 30wt% with Ce2O in solution. The best concentration is 50wt% with Al2O3 and SiC in solution.
    The second part of research is to analysis the relationship between parameters and roughness, and the relationship between parameters and contact angle. Contamination test is using the dark oil pasted on the glass surface, then count the pixels in one level color. The research showed that lower roughness the contact angle is the better. The contact angle is higher the stain resistance the better. So that the roughness is lower the stain resistance is the better.
