dc.description.abstract | 本文利用田口實驗設計法來規劃實驗,再藉由S/N比、灰色關聯分析法、主成份分析法和變異數分析,尋找PC/ABS的最佳射出成型條件,以達可以快速得到所需求的品質目標。實驗設計棌用田口方法中的L9直交表,選擇射出時間、熔膠溫度、模具溫度及保壓壓力為控制因子,每一因子皆選擇三個水準,其品質則是選擇破壞韌性、抗拉強度、伸長率、磨耗性質及硬度為評估的指標。利用田口方法的S/N比來求得單一品質的最佳射出成型製程條件,另外以變異數分析(ANOVA)來瞭解影響最鉅的控制因子。由於一般實務的要求都會希望達到多目標品質特性最佳化,但就田口方法難以直接處理多重品質特性的情況,因此選擇主成份分析以解決田口方法的限制,並另外利用灰色關聯分析來處理多重品質特性的問題,藉以瞭解同時考慮多重品質特性時的最佳射出成型製程條件,同樣以變異數分析來瞭解何種控制因子的貢獻度最大。
依據實驗規劃,進行準靜態拉伸實驗、破壞韌性實驗、磨耗實驗與硬度實驗,利用所得的實驗結果進行最佳化的分析。由最佳化分析結果得知,利用田口方法的S/N來考慮單一品質特性時,各品質所求得的最佳射出成型條件不盡相同,且以變異數分析的結果也發現影響各品質最鉅的控制因子也不一定相同,傳統方式上可以利用經驗法則來加以決定。而在處理多重品質特性時,採用灰色關聯分析所求得的最佳射出成型條件,和利用主成份分析結合田口方法的S/N比所得到的結果十分接近。因此在考慮多重品質特性的最佳射出成型 | zh_TW |
dc.description.abstract | The optimization of injection molding process for Polycarbon-ate/acrylonitrile-butadiene-styrene (PC/ABS) blends is studied using Ta-guchi method and principal component analysis (PCA). Four controllable process factors are studied at three lev-els each in the manufacturing process. The L9 orthogonal array is conducted to determine the optimum process fac-tor/level combination for single quality of mechanical properties. In addition, the principal component analysis is employed to transform the correlated mechanical properties to a set of uncorrelated components and to evaluate a comprehensive index for multi-response cases. Then the optimum process factor/level combination for multiple qualities can be determined. Finally, the analysis of variance is used to find out the most influential injection molding parameter for single and multiple qualities problems. | en_US |
