面向特征映射的原象与象特征描述

Representation on Inverse Image Feature and Image Feature of Feature Mapping Oriented

在对零件设计域与制造域间特征映射前后的原象特征与象特征信息分析基础上，给出了原象特征与象特征的数学描述方式。这一描述为构造原象特征到象特征的映射函数和进一步分析特征映射原理奠定了基础。

Based on the analysis of inverse image feature and image feature of feature mapping from design domain to manufacturing domain, the mathematical descriptions on the inverse image feature and image feature are given.These descriptions lay a foundation for constructing feature mapping function and for discussing feature mapping theory.
