In this work a rule-based computer aided process planning system (BOX-CAPP) for deep drawing of box (rectangular and square) shaped parts is developed. The part is represented by top and front views in different layers using the boundary representation (B-Rep) method in 2-D to model the part drawing, whose, Data Exchange Format (DXF) file include the basic entities (lines and arcs) of the drawing part under consideration. A Visual Basic (VB) code is developed to recognize the part dimensions (length, width, height, and part radii) of the box shaped part. A rulebase VB code for planning of the number of drawing stages is developed, where the part geometry, tooling parameters and load required are determined for each stage. Demonstrated example is presented.
