铝型材挤压模具CAD中型材截面的实体信息处理

Bearing Land Entity Information Organizing of Aluminum Profile Extrusion Die CAD System

铝型材挤压模具中,工作带起着非常重要的作用。本文开发了铝型材挤压模具CAD工作带的实体信息处理程序,对铝型材截面信息进行提取,从而根据这些信息进行模孔工作带的设计计算,并传到到UG/OPEN进行工作带图形绘制。本文中实体信息的提取主要包括实体元素信息的读取、轮廓分类和排序;信息的传递主要指从型材截面传递到所需格式的数据文件和数据文件与UG/OPEN之间的传递。

Bearing land plays a very important role in aluminum profile extrusion. The program of dealing with the bearing land entity information in aluminum extrusion die CAD system is developed. The program picks up the aluminum profile cross section information in order to design and calculate die hole bearing land according to these information and transfers the data to UG/OPEN to give the drawings. In this paper, entity information picking-up includes entity information reading and contours sorting. The entity information transfer mainly exists between profile cross-sectlon and data file in a certain format we need, as well as, hetween data file and UG/Open.
