To solve the problem of the automatic disassembly path planning for waste mechanic-electronic products in remanufacturing, one of automatic disassembly path planning methods based on assembly restraint and model interference examination of product assembly model was proposed. In this method, the direction collection was expressed by Gauss sphere which can be disassembled freely in unassembled parts. The possible disassembly direction set can be figured out through calculating the intersection of all assembly restraint Gauss sphere in parts. To verify the availability of the disassembly direction, the disassembled parts were scanned to be tool body along these directions, and the interference examination was performed through calculating the intersection between tool body and unstripped parts. The method is adapted to the needs of CAD/CAM integrated development system, and is effective and feasible by the software programming and practical engineering applications.
