The AMRF (Automated Manufacturing Research Facility) Part Model is a data format used to represent the information characterizing a part to be manufactured in the AMRF. The Part Model representation includes descriptions of a part''s geometry, topology, and features. The importance of Part Model lies not only in its representational capabilities but also in its function as the primary mechanism through which AMRF applications communicate with the AMRF data base. To facilitate the use of the Part Model by AMRF applications, a parser has been developed which interprets the Part Model and transforms it into a set of data structures. This paper describes the use of the parser and methods for accessing the data structures produced.
