设计—工艺意图映射模型及其实现方法的研究

Study and Implement on Mapping Model of Feature Intent between Product Design and Process

分析特征映射中的设计意图—工艺意图（指非几何形状信息）映射的必要性，建立设计意图到工艺意图映射的数学模型，并深入研究该映射函数实现中的关键技术，即特征映射实施过程中尺寸与形位公差映射的难点，特征交互作用后尺寸表达的变化及其有效性判定方法。

On the basis of analyzing the feature intent mapping between product design and process,the mathematical model of feature intent mapping between product design and process is constructed by using the tool of mathematics.The key problems in the implement of mapping functions are studied and resolved,including the difficult problems of dimension and geometric tolerance mapping,the conforming method of dimension validation in feature interaction.
