组合曲面的纵向加工等半径圆弧过渡曲面自动识别算法

Agorithm of the Longitudinal Method for Compounds

纵向加工已逐步成为等半径圆弧过渡曲面重要加工方法之一.对于单曲面片,纵向加工方法已基本成熟,但要将其推广到组合曲面中还必须解决如何在组合曲面中自动识别和组装等半径圆弧过渡曲面片等问题.据此,本文提出了在组合曲面中自动识别和组装等半径圆弧过渡曲面片的一组算法.

The longitudinal method was an important method for the constant radius blends. But now it is not adopted to compound, because there are various properties blending (different radius, different convex/concave nature) in a compound. For the longitudinal method adapted to compound, several vital problems should be solved: (1) the automatic identification of blends;(2) grouping in accordance with properties;(3) grouping according to whether blends are adjacent. To solve these problems a set of effective and corresponding algorithms are provided.
