摘　　要：挤压铸造工艺参数是挤压铸造的关键,目前主要通过实验和经验来确定,效率低。结合数据驱动制造的趋势,提出基于案例推理的挤压铸造工艺参数设计方法。将收集的工艺数据视为案例,然后构建挤压铸造工艺参数的马尔可夫毯约简非关键影响因素,去除冗余影响因素并建立案例属性的关系,在此基础上,应用信息熵确定彼此的权重,然后基于案例推理原理得到新材料铸件的工艺参数。通过实验和应用,证明了该方法的有效性和准确性,为挤压铸造工艺参数设计提供了新的方法,可大幅度节省设计时间,也加强了对已有数据的利用。The squeeze casting process parameters are the key factors in the process of squeeze casting.At present,they are mainly determined by experiments and experience,which is inefficient.Combined with the trend of data-driven manufacturing,a method of squeeze casting process parameter design based on case-based reasoning is proposed.The collected process data is regarded as a case set,and then the Markov blanket is established to remove the redundant factors of the squeeze casting process parameter,and the relationship between case attributes is established.Besides,the weights of case attributes are determined by using information entropy.Finally,the process parameters of new material casting were obtained based on the principle of case-based reasoning.To verify the effectiveness of the method,an example is applied.The proposed method provides a new method for the design of squeeze casting process parameters,which can greatly save the time of design and strengthen the use of existing data.
