In this study, quality function deployment (QFD) Taguchi method and grey theory to implement customers multiple quality characteristics in the polishing process of Ti-6Al-4V. In the polishing process of Ti-6Al-4V, this study uses QFD to evaluate customer requirements project and technical requirements project by questionnaire and previous experiments. Through QFD to evaluate the critical quality project, the experimental design using orthogonal array and S/N ratio of Taguchi method to find the optimal combination of the polishing parameter levels, and determine the relationship between customer requirements and technical requirements by confidence level of the analysis of variance (ANOVA). Finally, this study applying the traditional method and GM (1, N) model to analysis the priority of technical requirements. By the results of confirm experiment shows the grey theory’s result consistent with a confirm experiment. Therefore, GM (1, N) model might be more appropriate than the traditional method to apply in the QFD. Keywords:QFD, Taguchi method, Grey theory, polishing
