The Australian Research Council (ARC) Industrial Transformation Training Centre in Surface Engineering for Advanced Materials (SEAM) and their industrial partner, Romar Engineering Pty. Ltd. is investigating how the combination of both additive and subtractive manufacturing in a hybrid machine can be used to reduce the need for post-processing of additive components.
Factors such as quality of surface (i.e. roughness) and residual stress are key considerations.
The initial stages of the project will use the melt pool imaging available on the LASERTEC 65 3D machine and interpret this data with vision algorithms to provide input into machine learning. The machine learning will be used to assess if weld pool parameters can predict final project parameters.
