Experimental Test for Benchmark 1--Deck Lid Inner Panel
- General Motors Corp., Manufacturing Engineering, Die Center, 2000 Centerpoint, Pontiac, MI 48341 (United States)
The Benchmark 1 deck lid inner is designed for both aluminum and steel based on a General Motor Corporation's current vehicle product. The die is constructed with a soft tool material. The die successfully produced aluminum and steel panels without splits and wrinkles. Detailed surface strains and thickness measurement were made at selected sections to include a wide range of deformation patterns from uniaxial tension mode to bi-axial tension mode. The springback measurements were done by using CMM machine along the part's hem edge which is critical to correct dimensional accuracy. It is expected that the data obtained will provide a useful source for forming and springback study on future automotive panels.
