GAGE R & R EXERCISE in this example, we do a gage R&Rstudy on two data sets: one in which measurement system variationcontributes little to the overall observed variation(GAGEAIAG.MTW), and one in which measurement system variationcontributes a lot to the overall observed variation (GAGE2.MTW).For comparison, we analyze the data using both the ANOVA and theXbar and R method. The GAGEAIAG data was taken from MeasurementSystems Analysis Reference Manual, 3rd edition. (Chrysler, Ford,General Motors Supplier Quality Requirements Task Force). Ten partswere selected that represent the expected range of the processvariation. Three operators measured the ten parts, three times perpart, in a random order. For the GAGE2 data, three parts wereselected that represent the expected range of the processvariation. Three operators measured the three parts, three timesper part, in a random order Part 1: Use the ANOVA method withGAGEAIAG data 1 Open the worksheet GAGEAIAG.MTW. 2 Choose Stat >Quality Tools > Gage Study > Gage R&R Study (Crossed). 3In Part numbers, enter Part. 4 In Operators, enter Operator. 5 InMeasurement data, enter Measurement. 6 Under Method of Analysis,choose ANOVA. 7 Click Options. Under Process tolerance, chooseUpper spec - Lower spec and enter 8. 8 Click OK in each dialog box.Answer the following questions 1. In the session window output,what is the percent contribution for part-to-part? _____ 2. In thesession window output, what is the percent contribution for totalGage R & R? _____ 3. After answer questions 1 and 2 above,which do you, believe causes more of the variation, part-to- partor the measuring system? ________________________________ 4. If youknew that according to Automobile Industry Action Group (AIAG) thatyou can determine whether or not your measurement system isacceptable using the following guidelines. If the Total GageR&R percentage in the %Study Var column (% Tolerance, %Process)is: PAGE 1 Gage R & R EXERCISE Less than 10% - the measurementsystem is acceptable Between 10% and 30% - the measurement systemis acceptable depending on the application, the cost of themeasuring device, cost of repair, or other factors Greater than 30%- the measurement system is unacceptable and should be improved Ifyou are looking at the % Contribution column, the correspondingstandards are: Less than 1% - the measurement system is acceptableBetween 1% and 9% - the measurement system is acceptable dependingon the application, the cost of the measuring device, cost ofrepair, or other factors. What have you determined about thismeasurement system based on the %Study Var column for total Gage R&R?____________________________________________________________________________________________________________________5. Looking at the graph window output, what does the components ofvariation graph in the top upper left hand cornerindicate?____________________________________________________________________________________________________________________________6. Looking at the measurement by operator graph, which operatorseems to measure differently than the others? ________________ Step2: Use the ANOVA method with GAGE2 data 1 Open the file GAGE2.MTW.2 Choose Stat > Quality Tools > Gage Study > Gage R&RStudy (Crossed). 3 In Part numbers, enter Part. 4 In Operators,enter Operator. 5 In Measurement data, enter Response. 6 UnderMethod of Analysis, choose ANOVA. 7 Click OK. PAGE 2 GAGE R & REXERCISE Answer the following questions 1. In the session windowoutput, what is the percent contribution for Total Gage R&R?_____ 2. In the session window output, what is the percentcontribution for total part-to-part? _____ 3. After answerquestions 1 and 2 above, which do you, believe causes more of thevariation, part-to- part or the measuring system?________________________________ 4.
