博士 === 國立中央大學 === 機械工程研究所 === 91 === 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.
