March 1997
Progress is being made toward using rapid-prototyping techniques to speed the production of hard metal tooling
the convergence of design and analysis
Engineering software developers are merging computer-aided design and analysis programs to unleash designers' creativity and make specialists more productive
To meet the growing use of solid modeling, sophisticated analysis codes, and network communications, engineers have created a new desktop-computer architecture with the bandwidth and graphics power to support virtual product development
automating lens manufacturing
Computer-aided grinding and magnetorheological finishing are automating the manufacturing process for high-precision lenses such as those used in military and medical applications
determining gas-meter accuracy
Engineers at the Metering Research Facility are helping natural-gas companies improve pipeline efficiency by evaluating and refining the instruments used for measuring and setting prices
enlisting CFD to fight hammer shock in jets
Computational fluid dynamics can predict inlet hammer-shock loads for advanced tactical aircraft, a complex and costly task that has left existing methods grounded
failure analysis of a burner shield
The burner shields in a heat-recovery steam generator were modified to improve emissions. The unintended result was gross deformation of the shields, requiring an analysis of what went wrong
