摘　　要：滚抛磨块是影响滚磨光整加工效果和加工效率的关键因素之一,科学的评价指标集是对其进行合理评价的重要前提。因此,提出基于层次分析法(AHP)与主成分分析法(PCA)构建滚抛磨块评价指标集。首先通过分析评价指标选取原则,结合滚磨光整加工实际案例与滚抛磨块制备工艺,得到初始的评价指标集;然后以实际加工经验和加工数据为基础,将层次分析法与主成分分析法相结合,对该集合中的评价指标进行筛选,构建最终的评价指标集;最后分别依据初始及最终的评价指标集对滚抛磨块进行评价,并对比评价结果。结果表明:评价指标筛选合理,可根据最终建立的评价指标集对滚抛磨块进行合理的评价,从而减少评价指标数据采集的工作量,提高滚抛磨块评价的效率。The abrasive block is one of the key factors affecting the quality and efficiency of barrel finishing process.The scientific evaluation index is an important premise for the rational evaluation of the abrasive blocks.Therefore,the construction of evaluation indices of the abrasive blocks based on the analytic hierarchy process(AHP)and principal component analysis(PCA)is proposed.Firstly,combining the actual cases of barrel finishing process and the preparation process of the abrasive blocks,the initial evaluation index is obtained by analyzing the selection principles of evaluation index.Secondly,the AHP and PCA are combined to screen the evaluation indexes and then build the final evaluation indices.Finally,according to the initial and final evaluation indices,the abrasive blocks are evaluated and the evaluation results are compared.The results show that the selection of evaluation indexes is reasonable and the evaluation index can be used to evaluate the abrasive blocks reasonably,so as to reduce the workload of collecting evaluation indices data and improve the evaluation efficiency of the abrasive blocks.
