Assessing Measurement System VariationExample 1: Fuel Injector Nozzle DiametersProblemA manufacturer of fuel injector nozzles installs a new digitalmeasuring system. Investigators want to determine how wellthe new system measures the injector nozzle measuredNozzleData collectionTechnicians randomly sample, across all major sources ofprocess variation (machine, time, shift, job change), 9 nozzlesthat represent those that are typically produced. They codeOperator who measuredOperatorOriginal run order of the experimentRun OrderMeasured diameter of nozzle (microns)Diamthe nozzles to identify the measurements taken on first operator measures the 9 nozzles in random , the second operator measures the 9 nozzles in adifferent random order.
