A system for verifying assemblability is required for assembly planning in CAD/CAM systems for mechanical products, where the shapes of parts can be modified to make for easy assembly on the factory floor. In this paper a part assemblability verification system is introduced. Disassemblability is substituted for assemblability, and a system that generates paths for disassembly is constructed based on a solid modeling system for mechanical products. The developed system takes contact constraint and contact transition into consideration. An algorithm to derive movable directions of parts in the product which maintain contact states, and to calculate the positions and orientations of parts to change contact states is presented. An assemblability verification algorithm is also proposed using tree structural data whose nodes correspond to positions, orientations and contact states of each part and whose arcs denote movable directions. The efficiency of the system developed for the design verification and assembly planning is demonstrated through examples.
