The objective of this thesis is to design and develop a software tool that analyzes the incoming raw material inspection data obtained from a Coordinate Measuring Machine (CMM) and estimates feature variation created within the manufacturing process i.e. from the raw material stage to finished stage. This tool is used not only to disposition whether a lot is conforming or non-conforming, but also to provide the root installation operators an ideal N-angle, Leading Edge Angle (LEA) and Trailing Edge Angle (TEA) target that maximize the yield of the lot after further processing. The tool also helps reduce the number of airfoil sections which need to be inspected both at In-Process and Final CMM inspection stages, thereby saving a considerable amount of inspection time as well as providing estimated cost savings of over a million dollars a year to the business.
