摘　　要：STL作为CAD与RP系统之间数据接口的事实标准,所有的RP系统都支持该数据接口。分层处理是目前快速成形制造的首要环节。该分层软件采用STL模型整体拓扑信息的分层处理思想,分层处理效率高。分析了分层处理软件的总体结构和各模块的功能,给出其流程图,最后,为三维实体零件在计算机坐标系和在快速制模设备坐标系中的坐标转换问题,提出新的解决方案。STL is deemed to the factual standard of data interface between CAD and a RP system. It is most important to develop a effective slicing software for Rapid Prototyping manufactur- ing. The slicing thought of holistic topological information basedon STL model will be adopted in the slicing software, and slicing efficiency is high. Macro-frame of the slicing software and function of each module will be analyzed, and some flow charts are presented. Finally, a new solution of coordinate conversion for 3D models is put forward between the coordi- nate system on computer and the coordinate system of a RT facility.
