A gauge repeatability and reproducibility study was done at EngineBlader, Inc., which makes and repairs compressor blades for jet engines. The quality analyst collected the data for three operators, two trials, and ten parts, as found in the worksheet Ch08InstRsv.xlsx in the Instructor Reserve folder for this chapter. Analyze these data. The part specification is 4.7 0.1 inches. Calculate the process capability indexes for the parts. What does this tell you about the relative importance of part variation versus equipment variation and appraiser (operator) variation in assessing the gauging system?
