Interpreting the semantics of GD&T specifications of a product for tolerance analysis ?
STEP models are not capable for interpreting the product data semantics automatically. We discussed mapping of STEP models to OWL-based ontology. Products GD&T information mapped from STEP to OWL-based models. Implementations have been carried out in Protg using NISTs OntoSTEP plug-in. Ontology based model is used to interpret GD&T semantics for tolerance analysis.
