PRODUCT DATA EXCHANGE: The PDES Project--Status and Objectives

Published

Abstract

Throughout industrialized countries of the world, companies are using an increasingly larger number of computing systems in all phases of design, analysis, manufacture, test and long term support of their products. While system vendor, software design and engineering application vary widely, a common factor among these systems is that each computing application has its own internal mathematical model of the product. This is called a digital product model, and elements of information in the product model that describe the product are called product data. The term product data denotes the totality of data elements which completely define the product for all applications over it expected life cycle. Product data includes the geometry, topology, relationships, tolerances, attributes and features necessary to completely define a component part or an assembly of parts for the purposes of design, analysis, manufacture, inspection and product support. Very little if any process data is included, with the exception of aspects such as a heat treat specification. The product model is expected to be sufficiently complete as to enable the generation of all downstream process data.
