曲面零件立体造型中的过渡曲面

Research on interfaces in the modeling of parts

过渡曲面在计算机曲面立体造型中往往被忽略 ,而在曲面零件的实际加工中不可避免要涉及到过渡曲面的问题 .在讨论曲面之间形成的过渡曲面的性质的基础上 ,提出在立体造型中利用包络实现过渡曲面的步骤和计算方法 ,并给出了实例 .

The interface of surfaces is rarely been considered in the cube modeling of computer, but it cannot be avoided in the practical manufacture of surface parts. By discussing the property of interfaces base on differential geometry, the method of using enveloping surface to model the interfaces of surfaces can be obtained, and an example is given.
