The main focus of this research is to develop a schema based validation model for Geometric dimensioning and Tolerancing (GD & T). The ASME standard Y14.5 defines a set rule for GD & T to specify permissible variation in manufacturing. The new approach proposed investigates and classifies syntactic errors in a GD & T specification. The essential idea is to convert the ASME standards into grammar rules and use these rules in the form of a schema to validate any GD & T specification. The research also incorporates a datum evaluator based on grammar rules to check for ambiguities in datum referencing for any 3D CAD model. The proposed system has been verified using a series of experiments based on Monte Carlo simulation and multi stage random sampling.
