Realizing of Optimum and Automatic NC Code Programing Based on DXF Format

YAO Mian;TANG Hou-jun;School of Electronic Information and Electrical Engineering,Shanghai Jiaotong University;  
DXF is a file extension for a graphic image format typically used for interoperability with AutoCAD and specific graphics developing tools.Due to its randomness and disorderliness during the design process,traditional methods fail to generate NC code automatically with shortest path by simply reading DXF files line-byline.The aim of the study is to establish the storage structure of fragmented graphic entities with explicit spatial relationships.Contour tree and the nearest insertion algorithm for global path optimization are proposed for classifying and sorting.The simulation results indicate its reliability and feasibility in industrial application.
