A system for analyzing automatic assembly and disassembly operations

A system for evaluating products in their design phase has been developed. It is integrated into a CAD/CAM environment to calculate cost for assembling and disassembling parts. In previous work, a generic assembly and disassembly model was developed to represent operations required for product manufacturing and demanufacturing. To be useful, the model requires a method for translating high-level instructions from product designers into low-level assembly and disassembly instructions. This paper presents a set of rules for accomplishing this task. The developed rules are used for manipulating strings representing parts and handlers in binary assembly and disassembly operations. A telephone assembly and disassembly simulation is used to illustrate the developed system.
