摘要：A conformal map based global and local geometric planning approach to automated part finishing processes is presented in this paper. With the consideration of the complexity and difficulty of directly planning paths in 3D physical space, the proposed method firstly generates paths in the given planar region and then inversely mapping the paths on the machined surface. Some detailed issues such as step length determination and path interval computation are also addressed. By means of the mapping mode, some complicated path patterns such as spiral paths and multidirectional paths can be easily designed and obtained. The illustrated example of geometric planning shows the validity of the proposed method.
