  • Manufacture of complexly shaped articles using an automated design technique
    Patent number: 6340424
    Abstract: An integrated compressor disk and compressor blade (BLISK) having a specified shape is prepared by an electrochemical machining process having a cathode defined by a set of cathode shape parameters. A trial BLISK is prepared using a cathode defined by a set of trial shape parameters, and a set of deviations of the trial shape from the specified shape at a plurality of surface grid points on a surface of the trial article is measured. A set of revised cathode shape parameters is determined using at least one reshaping routine specific to the BLISK. A reshaped article is prepared using the electrochemical machining process and a reshaped cathode defined by the revised cathode shape parameters.
