摘要
由于快速成型机加工尺寸的限制,难于制造尺寸较大的零件。针对这一问题本文提出一种基于STL文件格 式的实体分割算法,对STL文件分割过程中的关键问题进行了详细地论述,包括:截面轮廓的生成,截交三角面片的 处理和截面轮廓的三角化算法;通过对STL文件的分割处理,提高了快速成型系统对大尺寸零件的制造能力。
There are some difficulties in manufacturing parts of jumbo size because of the limitation of dimension range of rapid prototyping system. To solve the problem a solid dividing algorithm based on STL file format is brought forward in this paper. The key problems are discussed in dividing STL file, including creating cross-section profile, processing the triangle facet divided and triangulation algorithm for cross-section profile. The ability of rapid prototyping system to manufacture parts of bigger dimension is improved by dividing STL file.
