Abstract: A method for controlling a power beam process includes carrying out a plurality of test power beam processes using a power beam on one or more test components and determining a plurality of power distributions corresponding to the plurality of test power beam processes. The method includes determining a plurality of beam parameters, generating derived features based on the plurality of beam parameters, and determining a plurality of process characteristics of each test power beam process. The method further includes generating a comprehensive dataset, dividing the comprehensive dataset into a test dataset and a training dataset, and determining a plurality of key discriminative features from the plurality of derived features of a set of training power distributions of the training dataset.
