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. Each operator repeats the processtwice, for a total of 36 valid measurement system analyses, you must randomlysample and measure specificationfor the nozzle diameters is 9012 4 tolerance is 8 Gage R&R Study (Crossed)Gage Studies for Continuous Data3 Assessing Measurement System Measurement systems analysisWhat is measurement systems analysisMeasurement systems Analysis assesses the adequacy of ameasurementsystem fora output from a process, consider two sources
