Abstract:

This paper deals with the generation and validation of a thermal deformation model that is to be used as one aspect of monitoring the performance of a machining center. The models considered are empirically derived using data from temperature and displacement sensors. The thermal deformation is produced by using the machining center under normal operating conditions but without cutting. Comparison between two different modeling techniques enables the most 'suitable' model to be chosen. These models are validated by assessing their prediction success on new, previously unseen data. Validation of each model's inputs is achieved through the use of an expert system shell and rules about the correct behavior of each of the temperature sensors derived from information gathered during the tests.
