With manufacturing plants throughout the world, producing parts for a wide variety of automobiles, Chrysler® Group recognizes that quality control must be exercised with perfection in its entire manufacturing value chain. At Chrysler® Group's Kokomo Transmission Plant in Kokomo, Indiana, automobile transmissions are assembled from hundreds of parts and cut with precision instruments.
Redefining Flatness Measurement
Flatness measurement is a critical component to Chrysler® Group's
transmission assembly. Each part is machined within a strict tolerance
range as set by product design engineers and pass final inspection before
being released to the manufacturing assembly process. Through the use
of traditional CMM instruments, Chrysler® Group identified and maintained
acceptable flatness standards.
However, in the pursuit of higher part
quality, the company wanted a method
to measure a greater level of flatnessper-
inch to increase performance of
its plant's "Finishing Operation". To
do this, they required an instrument able to provide them an actual"fingerprint", or cut pattern for each part.
Their existing CMMs only provided a
limited number of points of touch, and
failed to deliver the necessary measurement
information. That's when Coherix
