Quality Assurance Verification Using Portable CMM

GE Healthcare manufactures and maintains high quality medical analysis equipment. The Florence, South Carolina, plant manufactures Magnetic Resonance Imaging (MRI) equipment such as the Signa HDx and Signa MR750 series machines.






The basis for the machine is a wound fiberglass shell enclosure.  The shell is then machined to very close tolerances.  The magnetic windings and electrical circuitry are carefully installed into the closely machined cavities.

 

                                Machined Fiberglass MRI Shell QA Measurements




GE Healthcare hired BC Engineering and Design to perform verification checks on the machined shells.  The task for BC Engineering and Design engineers was to periodically compare the final machined shell to the 3D solid CAD model provided by GE design engineers and to verify that the final product matched the theoretical CAD model.

BC Engineering and Design performed the QA checks using a FARO Platinum series portable Coordinate Measurement System.  Through a series of measurements on several sample shells, BC Engineering and Design engineers were able to assist GE in refining their manufacturing process to ensure a consistent product was being produced to the close tolerances necessary for high quality MRI processing.
