Abstract: A system for automated adaptive manufacturing of airfoil castings is disclosed. The system may receive a three dimensional scan of a work piece. The system may compare the three dimensional scan to a digital model of the work piece. The system may identify an area of dimensional abnormality on the work piece based on the comparison. The system may alter the area of dimensional abnormality on the work piece.

Abstract: A method of removing features from a cast workpiece includes generating a nominal toolpath for machining the cast workpiece. The cast workpiece is mounted onto a platform of a computer numeric control machine. The cast workpiece is inspected with a probe to generate probe data. Features to be removed are identified based upon the probe data generated during the inspection. Any expected features of the cast workpiece that are missing from the cast workpiece are identified. A transformation matrix is applied to the nominal toolpath with a controller of the computer numeric control machine, wherein the transformation matrix is based upon the probe data. Alignment of the cast workpiece is adjusted relative to the computer numeric control machine based on the transformation matrix with the computer numeric control machine. Features are removed from the cast workpiece that were identified during inspection.

Abstract: A method of manufacturing an aerodynamic element with an edge is provided. The method includes producing the aerodynamic element with an initial condition, cooling the aerodynamic element, generating a predefined number of data points sufficient to characterize contours of the edge and comparing the data points to a nominal condition to derive transformation parameters applicable to cutting toolpaths to adapt the cutting toolpaths to the initial condition.

Abstract: A method of manufacturing a casting is provided and includes establishing desired dimensions of a nominal casting, executing a casting process to produce multiple actual castings with each of the multiple actual castings having respective dimensions that differ from each other and from the desired dimensions of the nominal casting and engaging one or more tools to adaptively machine, without rigidly-programmed toolpaths, each of the multiple actual castings to reduce the respective differences between the actual dimensions of each of the multiple actual castings and the desired dimensions.
