模具型腔设计中不规则分布型值点构造自由曲面的研究

CONSTRUCTION OF FREE-FORMED SURFACE FORM RANDOM DISTRIBUTED DATA POINTS IN MOULD CAVITY DESIGN

不规则分布型值点构造自由曲面是ＣＡＤ／ＣＡＭ中的重要问题，在模具型腔设计中也常遇到的．本文试图提出一种对型值点加权平均方式构造自由曲面的方法．

In the field of CAD/CAM,especially in Mould Cavity Design,it is a frequent occurence that rardom distributed data points form a free-formed surface.In this paper, the free-formed Surface is constructed from weighted means of the data points.
