The objective of the PDDI project was twofold. Task I establishes the current state of ANSIIGESInitial Graphics Exchange Specification implementation through the application of test procedures against current graphics systems. The major emphasis of the project is in Task II - a definition of long-range manufacturing needs and the demonstration of a prototype product definition data interface to meet these needs. This system is intended to serve as the information interface between engineering and all manufacturing functions using todays blueprint, including process planning, numerical control NC programming, quality assurance, tool design and others. The Product Definition Data Interface PDDI will be demonstrated together with an advanced Numerical Control Programming system and an advanced Process Planning system in order to prove the concept. In addition, it will be interfaced to two commercial CADComputer Aided Design systems to demonstrate its general applicability. Objectives included a thorough analysis of manufacturing information needs for Product Definition Data PDD using sample aerospace parts definition of an automated framework for a Product Definition Data Interface PDDI development of data format and utilities required to support the PDDI and proof of concept of the PDDI through demonstration of the utility software.
