Design for manufacturing is often difficult for mechanical parts since significant manufacturing knowledge is required to adjust part designs for manufacturability. The traditional trial and error approach usually leads to expensive iterations and compromises the quality of the final design. The authors believe the appropriate way to handle product design(More)
Some of the most significant challenges in automated CAD–FEA integration are information and model transformations between CAD and FEA tools. These are especially labor-intensive and time-consuming in a newly characterized class of problems termed highly coupled variable topology multi-body (HCVTMB) problems. This paper addresses these challenges with a(More)
The Advanced Photon Source (APS) is a 7 GeV storage ring light source that has been in operation for well over a decade. In the near future, the ring may be upgraded, including changes to the lattice such as provision of several long straight sections (LSS). Because APS beamlines are nearly fully built out, we have limited freedom to place LSSs in a(More)
Mechanical parts with complex geometry features, especially free-form surfaces, are being used widely in the industry. Digital manufacturing techniques have recently been developed to manufacture free-from surfaces with high quality and low cost. In this paper, an integrated digital manufacturing strategy is presented, in which free-form surface are(More)
As engineering systems are increasingly becoming more complex, the need for information models is growing accordingly. Extensive research is currently underway to develop engineering data management capabilities and to understand the role of information as a systems integrator. In order to develop information models more effectively, a systematic(More)
