This report examines the usage of 3D non-contact white light (WL) measurement technology and how its adoption could impact traditional North American automotive body dimensional evaluation strategies from die tryout through PPAP. The report includes several WL measuring studies involving a longitudinal analysis of door components and their resultant(More)
When using the functional build approach to manufacturing validation during new product development, manufacturers use pre-production assemblies to evaluate whether components within an assembly may build dimensionally correct products. This approach allows some individual component characteristics to not meet their original design specifications, provided(More)
Several manufacturers are adopting six sigma programs in efforts to reduce stamping variation. This requires the crucial step of establishing dimensional relationships for the stamping dimensional outputs that become key process inputs to the assembly process. This paper describes a methodology used to determine the root cause of dimensional changes in a(More)
