摘要: 
本研究在提出一套多補塊曲面的粗切刀具路徑產生的方法。利用此種方
法可以對多個B-spline曲面構成的幾何模型,進行保証不過切的多補塊曲
面粗切。這種多補塊曲面的粗切方法是先構建多個B-spline曲面,將其個
別地轉換成Bezier曲面,再以所有的Bezier凸盒長方體組合而成曲面近似
模型。然後對曲面近似模型以切割平面的方式做非等間距分層,分層之後
,視每個切層為一口袋形模穴,以口袋形模穴的銑切方式,來產生粗切刀
具路徑。

The objective of this reserch is to present a rough cut
method for multipatch B-spline surfaces. Several B-spline
surfaces are constructed primarily, and each one is decomposed
individually into Bezier surfaces.All of the Bezier convex hull
boxes are unioned together to form an approximate model. Thue,
a rough cut plan applies to the approximate model by slicing the
stock into nonuniform layers. Therefore, the NC rough cutpaths
are generated automatically by treating each layer as a 2D
pocketdie cavity.
