The choice of tool in milling magnesium alloy is a comprehensive decision-making problem with multiple index factors.A grey comprehensive evaluation model for tool performance based on game theory,which coordinates subjective and objective weighting,is proposed for product features processing require-ments.In this method,it is proposed to combine improved analytic hierarchy process(AHP)and entropy weighting method to reduce the influence of subjective factors.In addition,a grey comprehensive evaluation model based on combination weighting was established by grey relation analysis.Finally,experiments of CNC milling characteristic similarity structure of an active product used in a certain satellite were carried out,and then the established evaluation model was applied to evaluate and verify the performance of alter-native cutting tools.In the three alternative cutting tool tests,the results show that grey comprehensive eval-uation can effectively evaluate tool performance and provide a basis for tool selection in actual processing.
