Ladish has finished computer modelling the forging processes for critical components of the Rolls-Royce Trent 500 turbofan being developed to power the Airbus A340-500/600. The Cudahy, Wisconsin-based company is producing several components for the engine.
Process modelling eliminates the traditional approach of developing components using a step-by-step, trial-and-error methodology. Components emerge from process modelling sufficiently well defined that the first piece forged can be used as a production part, according to Ladish.
Using a database of forging process models built up over 12 years, Ladish claims over 95% accuracy in predicting the distribution of grain size and mechanical properties throughout a finished component. The company says it can describe how different materials will behave on different pieces of forging equipment, as well as in the heat treating, quenching and machining processes.
