Tesco and CogniTens Inc. joined forces, at the urging of General Motors Corp. and with funding from the BIRD Foundation, to develop a measurement system specifically tuned to the needs of automotive BIW assemblies. The result is the I3 Measurement Cell, which reduces auto makers’ costs for developing, testing and monitoring expensive product-specific tooling. GM uses the I3 approach extensively to evaluate, fit and finish the interior and exterior of the Pontiac Solstice roadster and the Chevrolet Tahoe SUV.
