概念设计中的夹具几何特征识别

Identifying Geometric Feature of Fixture in Concept Design

针对概念设计中对零件几何分析的要求，从零件的几何特征角度，制定了一系列夹具几何特征的判定准则，探讨了夹具特征的类型、定义及其具体的识别算法。并利用Visual C++语言和AutoCAD R14的二次开发工具ObjectARX，对中等复杂程度的零件完成了夹具特征识别。

In this paper, as viewed from the geometry feature of the mechanical components, a series of determinant rules about geometrical feature of fixtures were worked out with focusing attention on the requirement of geometrical analyses of the components in conceptual design. The types and definitions of fixture feature, as well as their specific recognition algorisms were discussed. The recognition of fixture feature for the middling-complex components were accomplished by using Visual C++ language and AutoCAD R14 developed application programmer-ObjectARX which is a object oriented method of developing application.
