摘要
对汽车覆盖件模具CAD/CAM的整个工作流程分析表明:曲面造型是汽车覆盖件模具CAD/CAM的基础,它的准确与否将会直接影响模具的数控加工质量。本文介绍与曲面造型方法有关的几个概念及算法,重点分析了在汽车覆盖件模具上出现的压肩曲面、拔模角曲面、圆弧型过渡曲面及混合曲面的特点,并根据这些曲面的特点提出了它们的造型方法。
Analyzing the whole process of CAD/CAM for automobile covering panel dies indicates that surface modeling is the essential base of the process, and its precision will directly affect the NC machining quality of the dies. This paper describes some concepts and algorithms related to surface modeling. Analysis emphases are put on the characteristics of the typical surfaces, such as shoulder-overlapping surface, draft surface, fillet surface, and blending surface, and their modeling methods are proposed accordingly.
