The past decade has witnessed the development and initial introduction of various process models through computer simulation. Led by programs sponsored by the USAF, WRDC, Manufacturing Technology Directorate, the first achievement of this effort was the development of the ALPID software and its subsequent application to the extrusion and isothermal forging of superalloy turbine disks for jet aircraft engines. The reliability and accuracy of the evolved models have resulted in more rapid technical response from forging suppliers, improved quality and consistency in the forged product, and lower costs. Forging models have since been applied to any number of more conventional forging alloys and processes. But, perhaps of more importance to the industry as a whole, these process description and control concepts and disciplines now have also been extended to a wide variety of other material and process applications.
