Design for Maintainability and 3D-Based Technical Publication Generation
During the evolution of a product design and manufacturing process planning, the same PPR dataset can be used to validate the maintainability of a product, as well as to develop technical-publication documents containing text, images, and movies derived directly from the 3D-based process plans. The core PPR technology supports any number of views of process-planning data related to product and resource, thereby providing a way to associatively develop maintenance plans concurrent with manufacturing planning. This ability to concurrently validate the design as well as the maintenance operations for a product is one more example of the significant leverage provided by the PPR data model. This allows the idea of leveraging the results of 3D process planning and analysis directly into Web-based technical publications for maintenance operations (e. g., analysis of 3D process plans for producibil – ity and Web-based technical publications for maintenance). 3D enables a new business paradigm, as follows:
• 3D is now leveraged not only for design but also for manufacturing planning, simulation-based validation, work-instruction authoring, and delivery to the shop-floor workforce, enabling a true paperless manufacturing process. This is easily extended for 3D maintenance and repair instructions.
• Operational and maintenance scenarios can be simulated using ergonomic analysis early in the design cycle to provide efficiencies later in the life cycle of a product. With a systematic methodology, a true design for customer business process can be supported.
• The virtual production mock-up eliminates the requirement for prototype parts to prove out mock-ups of production tooling and fixtures, reducing cost and time.
• Tooling orders can be placed much later in the development plan with the latest design revisions incorporated because they will work the first time, eliminating costly change orders to tools and parts designs.
• Designs can be modified early in the design cycle to accommodate manual assembly and maintenance tasks; therefore, the requirement for special tools can be eliminated.
In the near future, the conceptual design stage of a new aircraft project must assess in detail and then incorporate the benefits that can be derived from the digital manufacturing process management.
