Application of the Step-by-Step Regressive Analysis to the Design Criterion Mining of Forging-Die Flash Sizes

分析了采用传统方法建立锻模飞边尺寸设计准则存在的问题,提出了采用逐步回归分析法挖掘锻模飞边尺寸设计准则的思想,构造了利用逐步回归分析法对锻模飞边尺寸设计准则进行参数估计的算法;对逐步回归分析软件的需求分析与结构设计及该软件中数据的分析与设计进行了论述;以此为依据开发了该软件,并给出了利用该软件获得的锻模飞边尺寸设计准则.结果表明,利用由此得到的设计准则而开发的CAD系统具有自组织能力和自适应能力.

Some problems in setting up forging-die flash size design criteria by means of traditional methods were analyzed. The idea of applying the step-by-step regressive analysis method to mining forging-die flash size design criteria was pointed out and the algorithm of estimating the parameters in forging-die flash size design criteria was constructed. The requirement analysis and structure design of the step-by-step regressive analysis software, and the data analysis and design within the software were expounded. According to these ideas, the software was developed. The design criteria of forging-die flash sizes with the software used were given. The results showed that the CAD systems developed using these criteria had self-assemble ability and self-adaptive ability.
