Digital manufacturing is essential to meeting the manufacturing requirements of agility and responsiveness. This paper reviews work carried out at the authors' Manufacturing Engineering Centre (MEC) on advanced uses of manufacturing information pertinent to digital manufacturing. The work covers developments in intelligent conceptual design, advanced manufacturing information provision for detailed design, intelligent product manual generation, rapid manufacturing, and business process modelling. The work presented in this paper is within the scope of I*PROMS, a major project coordinated by the MEC. Key features and the achievements to date of the project are described.
