| dc.description.abstract | 本研究是以自行開發的行星機構結合二維振動輔助磁力研磨機制於不鏽鋼材料上進行拋光，其主要目的是利用行星機構自轉與公轉的特點，使表面形成高密度的交叉紋路外，還可以達到節能、省時。進而達到高品質、高效率、低耗能的指標。藉由控制磁極間距、振動平台振幅、鋼砂粒徑、SiC重量、鋼砂重量、研磨液重量、振動平台頻率、磁極轉速…等一系列的實驗探討後，得知行星機構結合二維振動輔助機制能夠提昇表面品質及效率。
經由田口驗證實驗可以得知，對於表面粗糙度的改善較佳參數組合為：磁極間距1 mm、振動平台振幅0.1 mm、鋼砂粒徑0.125 mm、SiC重量3 g、鋼砂重量0.5 g*2、研磨液重量5g、振動平台頻率16.667 Hz、磁極轉速500 rpm(156) (A1B1C3D2E3F3G2H2) 。
行星機構結合二維振動輔助磁力研磨加工法在較佳參數組合下，能於12.5分鐘內有效改善不銹鋼表面粗糙度由Ra0.16μm降低至0.032μm，改善率為80%，研磨20分鐘後更能達到0.023μm，表面改善率提高至85.63%。若單純只有二維振動輔助之下，改善率為68.75％(Ra0.05μm)；或者單純只有行星機構之下，改善率為63.13％(Ra0.059μm)，由此可以證明行星機構結合二維振動輔助機制是能提昇品質的。
最後深入探討行星機構的特性，利用行星機構與單軸不同轉速之下，來探討其省時及效率；亦用電力計來量測行星機構與單軸旋轉所消耗的功率，來探討其節能之效果。

| dc.description.abstract | A study of magnetic polishing for SUS304 with planetary bodies combined two-dimensional vibration. The main purpose of the planetary bodies of rotation and revolution characteristics, excellent surface morphology, and saving energy and time can also be reached. Series of experiments by controlling the working gap, the amplitude of the vibration platform, steel particle size and so on. This mechanism can enhance the surface quality and efficiency.
Taguchi experiment show that the combination of better parameters for the improvement of S.R.: working gap 1 mm, the amplitude of the vibration platform 0.1 mm, steel particle size of 0.125 mm , SiC weight of 3 g, steel weight of 0.5 g * 2, the weight of the slurry 5g, vibration platform frequency of 16.667Hz, magnet pole rotational speed 500 rpm (156) (A1B1C3D2E3F3G2H2).
This mechanism can be effective in improving the stainless S.R. of 12.5 minutes to reduce by Ra 0.16 μm to 0.032 μm, improvement rate was 80% after 20 minutes can be better achieved 0.023 μm surface to improve the rate increased to 85.63%. If simple Only two-dimensional vibration assisted under the improvement rate was 68.75% (Ra 0.05 μm); or simply under the planetary bodies to improve the rate of 63.13% (Ra 0.059 μm), which can prove that planetary bodies combination of the two-dimensional vibration support mechanisms to improve quality.
The final depth the characteristics of the planetary bodies, the use of planetary bodies and under uniaxial different speed, and to investigate its time-saving and efficiency; also to explore its energy-saving power consumed by the power meter to measure the planetary bodies and uniaxial rotation effect.
