Abstract

Inspection is one of the primary concerns in manufacturing industry. When the dimensional tolerance requirements of manufactured parts are tighter, inspection planning and execution becomes very important The inspection operation accounts for a fairly large portion of the manufacturing lead time of finished parts as well. In recent years, the coordinate measuring machines are widely used in industry to improve efficiency in inspection operation. For inspection planning, the strategy for measuring the dimensions of a part can be determined by considering the features that constitute a part In this research, an architecture for an automated inspection planning system with a feature-based representation is designed for automated inspection using coordinate measuring machines. A part is represented using a destructive solid geometry (DSG) tree structure with primitive geometric features. In the architecture, inspection primitives and datum planes are identified using the DSG data. It also includes a structure for generating necessary tolerance measures for a part The inspection plan for a given part is then generated by an expert system module. The generated inspection plan was demonstrated on a coordinate measuring machine for two test parts.
