Materials data management


Materials data is a critical resource for manufacturing organizations seeking to enhance products, processes and, ultimately, profitability. This data describes the properties and processing of the materials that these organization uses - metals, alloys, plastics, composite materials, ceramics, etc. This data may come from a wide range of sources - e.g., materials testing, quality assurance, or measurement of product performance. The process by which manufacturers manage and use such information is one essential 'cog' in the larger machine that is the product lifecycle.

One project that has looked at this issue in-depth is the Material Data Management Consortium (MDMC), a collaboration of leading aerospace, defense, and energy enterprises - organizations such as NASA, Boeing, Rolls-Royce plc, Honeywell, and GE Aviation. The MDMC has identified the problems caused by failures in the materials data management process and investigated how an optimized process can lead to better innovation and quality.

Problems typically relate to productivity and data integrity. They begin with difficulties in consolidating specialized data stored in disparate sources and varied formats. Problems continue with the challenge of controlling and using approved information effectively throughout an organization, often within complex processes. These include:

This final issue ('traceability') is particularly important in quality and safety-conscious industries (such as aerospace or medical devices) where engineers need to be able to trace the full pedigree for a manufactured component - ideally, not just back to the design, but to all of the raw (materials and other) data used to create the design. This need for traceability has been a key driver for many commercial materials data management projects.

Materials data management is not just about the avoidance of problems and risk. The MDMC reports that best practice materials data management can have very positive effects on innovation and quality. For example, Rolls-Royce Aerospace have described how the ongoing assessment and analysis of all of the materials property information generated across the testing and design process can allow an organization to continually refine the 'allowable' values used in design, leading to improved product performance.
