The objective of this research is to integrate computer aided design (CAD) and computer aided manufacturing (CAM) through automated feature-based process planning. This integration process is accomplished through two steps. First, a feature recognizer is used to recognize and extract form-features from the solid modeling database of a designed part. The form-features and related parameters are compiled into a feature-graph as the output from the feature recognizer. Second, a generative process planner is used to produce a process plan for the part described by the feature-graph. A knowledge-based system called FRAPP (Feature Recognizer and Process Planner) was developed using artificial intelligence (AI) concepts to perform the two tasks. FRAPP uses frame-based knowledge representation to store part descriptions, machine specifications and manufacturing criteria. Decision logic is represented as production rules.
