摘要

本研究應用冪次律損失函數田口方法結合灰關聯分析於304不銹鋼拋光製程中找尋中心線平均表面粗糙度(Ra)、最大表面粗糙度(Ry)、移除量、平坦度、光亮度的個別最佳拋光參數水準組合，以及多重品質的最佳拋光參數水準組合，並進行確認實驗與預測值相互比較。
實驗結果顯示，單一品質中心線平均表面粗糙度(Ra)的最佳拋光參數水準組合在n=1、2時為A2B2C2D1，在n=3、4時為A1B2C2D1，單一品質最大表面粗糙度(Ry)的最佳拋光參數水準組合在n=1時為A2B2C2D3，在n=2、3、4時為A2B2C2D1，單一品質移除量的最佳拋光參數水準組合在n=1、2、3、4時為A2B1C2D2，單一品質平坦度的最佳拋光參數水準組合在n=1、2、3、4時為A3B3C2D3，單一品質光亮度的最佳拋光參數水準組合在n=1、2、3、4時為A1B2C2D1，多重品質的最佳參數水準組合在n=1、2、3、4時為A2B2C2D1，經由確認實驗得到在n=1時誤差百分比為11.59%，在n=2時誤差百分比為13.51%，在n=3時誤差百分比為12.9%，在n=4時誤差百分比為11.99%，發現在n=1時誤差百分比最小。
