高單價、高附加價值的不銹鋼市場一直是全球鋼鐵業界的重點市場，而且不銹鋼的特性是其他金屬不能替代的，其抗腐蝕性能也優於一般的金屬。即使在相當的高溫中，不銹鋼的強度也不會受太大的影響。近年來，因為不銹鋼的優良性能，得到廣泛的認同，特別在電子產品、汽車零件、家庭電器等日常生活方面也得到應用。其中不銹鋼細線的應用可以說是越來越廣泛，漸漸成為許多產業中相當重要的一種材料。目前國內仍無廠家可提供線徑20微米（0.02mm）的不銹鋼細線，其主要的來源是日本，若能研發成功20微米的不銹鋼極細線，將可提供國內下游廠商的需求，更可在全球的競爭上占得有利的位置。
本研究計劃應用直交表（Orthogonal Array）配置實驗，利用田口方法（Taguchi Method）等方法，分析直交表實驗所得的資料，研究出關鍵因子（Key Factors）與水準（levels），找出最佳化製程參數的可能方向，然後應用反應曲面方法（Respond Surface Method），簡稱RSM來評估其主因子、水準範圍內所呈現的品質特性，求出製程可能的最佳參數。當品質特性稍有變化時，也可利用反應曲面來預估製程可能的反應，以適度調整其因子、水準，而達到滿足品貭特性的要求。執行驗証實驗以確認最佳參數水準組合之再現性。盼此一研究之成果，可做為元能公司參考依據，能建構出一套優質製程技術，才能增強公司企業的競爭力，而使企業能永續經營、基業長青。

The stainless steel market of high unit price, high additional value has been a key market of the global steel industry all the time, and the characteristic of the stainless steel can’t be substituted by other metal. Its anticorrosive performance is superior to the general metal. Even in the suitable high temperature, the intensity of the stainless steel will not be influenced. In recent years, because of the fine performance of the stainless steel, it has been widely used in daily life, such as on electronic product, automobile part, family electric apparatus, etc.. The application of the stainless steel can be regarded to gradually become more extensive upon important materials in a lot of industries. Currently, there is still no production in Taiwan that can offer finest stainless steel wire at a diameter of 20 microns (0.02mm). Right now the main source of its production is in Japan. If this research project can succeed in developing 20 microns finest stainless steel wire, then we can meet the demand from domestic downstream manufacturing industries. By doing so, we can be in the position to stay ahead in the global competition.
In this study we use the orthogonal array to design experiments and run the experiments in order to improve the drawing process of 20 microns of stainless steel wires. Taguchi methods are applied to analyze the experimental data. We expect to find out the key factors, level combinations, and the optimal values of the parameters for best effect in the production. Then, the respond surface method will be used which shows the quality characteristics within range of the key factors and assumed levels .Thereafter we can estimate the optimum parameters to optimize the response. Variation on the quality characteristics can be investigated by easily adjusting the deciding factors and levels to achieve best effect on the desired quality characteristics. Experiments shall be run to confirm our prediction. All the methods and procedures used in this research can be applied in the production process at Yuen Neng Co. Ltd., Hopefully, the outcome of this research can be referred as a guiding light in the company which leads us to obtain superior production technology. Then, we will be able to raise our competition capability and keep our operation moving on a firm basis.
