【 摘 要 】

This study presents the multi-performance analysis in drilling of A356-TiB2/TiC in-situ composite produced through stir casting route. A novel Entropy-VIKOR approach is adopted for the optimization of parameters in drilling like spindle speed, drill diameter and % of reinforcement over the MRR, delamination and surface roughness. Experiments were conducted on vertical machining centre by using of carbide drills followed by Taguchi L27 orthogonal array. The Entropy weight measurement method was used to evaluate individual weights of each response. For the multi responses optimization VIKOR indexing method was adopted. In this paper, the multi-objective responses are converted as a single VIKOR index, and the ANOVA was performed for VIKOR index to determine the influence parameter for drilling. Finally, confirmation experiment was performed and validated using the regression equation to recognize the effectiveness of proposed method. Result of ANOVA indicates that reinforcement ratio has strongest influence on VIKOR index.
