Casting shape optimisation via process modelling

The paper describes the application of numerical optimisation case studies to two practical cast components. The first study highlights the potential benefit of thermal controls to achieve an optimised cast part, whereas, the second focuses on shape optimisation. In comparison with practice, it was noted that the unconstrained optimisation for thermal control identified the improvement path correctly, but the solution could not be applied practically. The shape optimisation study also identified the correct improvement path and the result was supported by trials that had been completed previously in the foundry.
