Based on gray correlation analysis,technique for order preference by similarity to ideal solution(TOPSIS)analysis and analytic hierarchy process,a multiple objectives and multiple contributing factors analysis method was put forward,which was proposed for the whole processes of the mold finishing.Gray correlation method was used to analyze the correlation degrees among multiple parameters,and TOPSIS was used to analyze the correlations among the multi-processing quality evaluation standards.Through the hierarchical method,a reasonable weight matrix was obtained,which combined the objectivity and subjectivity.The influence degree of each processing parameter on each standard and the correlation forecast model might be obtained via ANOVA analysis.Besides,this method was applied to the surface finishing of laser hardened mold,and the results manifests the method is practical and effective.
