基于特征造型的轴类零件设计系统

The design system of shaft parts based on feature modeling

以特征造型思想为基础,用VB 6.0和Access 2003为开发工具对Autodesk Inventor进行二次开发,开发出轴类零件设计系统。系统采用模块化结构,主要阐述了信息输入及处理模块、特征造型模块、工程图绘制模块等主要模块及其实现方法。系统能够对不同形状的轴类零件进行计算机辅助设计并生成工程图,具有记录建模过程并实现人机交互功能的特点,显著的提高了设计效率。

Based on feature modeling,using VB6.0 and Access 2003 as tools,a design system for shaft parts has been accomplished with the further development of Autodesk Inventor.On the concept of module structure,this system is composed of three main modules which are module of data input and pro-cessing,module of feature modeling,and module for project drawing plotting. This system can facilitate de-sign of all kinds of shaft parts with varied shapes and project drawing is generated,which have the advan-tage of recording modeling process and human-computer interaction,improved the design efficiency signifi-cantly.
