$99,997Benefits:
Availability of the tool can help prevent the static failures which have occurred during the manufacturing process development for cold-working of high strength aluminum alloys with reduced strengths in the ST direction. It can also help prevent the premature fatigue failures resulting from the use of a non-optimal interference level for the member geometry. With such a tool, the trial-and-error manufacturing and test-based design development process currently required to qualify a cold-worked member can be substantially reduced, leading to shorter cycle times, and lower weapon system acquisition costs.
