Application of Grey Correlation Analysis on Tool Selection
Tool selection is the important content of CAPP, and a great many influence factors and selection principles must be considered during tool selection. For the unreasonable phenomenon during tool selection and usage in present manufacturing enterprise, first the rule reasoning and fuzzy theory method are used to select proper tool set according to the processing conditions, then grey correlation analysis method is used to calculate the weight value of each tool and compare superiority of the these tools, and the best tool in existing conditions is obtained. Grey theory is used in tool selection to work out the problem of insufficient and incomplete information in the process of tool selection, and the cumbersome factors are simplified, the accuracy and efficiency of tools selection are improved. The research result has all-right reference meaning to other decision-making systems.
