Methodology for Recognizing Manufacturing Features of Prismatic Components from DXF Files

Recognition of manufacturing features associated to certain parts using DXF files have been proposed by a number of reseraches. Since the database stuctures that provide geometric information regarding the parts differ from one CAD system to another, the interpretation and modification of these data are difficult or impossible. This paper presents an algorithm for extracting the design features from a data exchange file format, supporting the development of automated process planning system for prismatic parts.
