A Conceptual Architecture for Mechanical Parts Production System Based on STEP



Edward J. Barkmeyer Jr., James E. Fowler, S Magleby


The STandard for the Exchange of Product Model Data (STEP) is an emerging standard addressing the problems of data exchange and representation of produced goods in a variety of manufacturing enterprises. Given that the initial STEP specifications largely pertain to mechanical-parts production, this domain is an appropriate context for initial STEP implementations. This document describes an architecture for systems realizing a mechanical-parts production capability using STEP data exchange. The functions of the major systems and relationships between systems are discussed. Software components which could be used to implement major systems are identified. Major emphasis is given as to how STEP is implemented and used in the context of the architecture.
