A disassembly support system including parts cutting is presented. Recently, DFD, DFR, and DFE have been proposed from a viewpoint of ecology. It is ideal that all parts are completely disassembled for effective reuse/recycle of them. However, design considering such complete disassemblability is unreal because required specification of products and/or their manufacturability is more important than it. Therefore, used products have been cut, broken, and/or shredded, and individual materials have been collected from mixed shreds in recycle factories. Furthermore, there are no detailed manuals with respect to cutting position and disassembling/cutting procedure in recycle factories. Our developed system generates feasible disassembly sequences including cutting position from CAD data and information with respect to reuse/recycle of each part. First, it generates disassembly/cutting sequences to retrieve reused parts and/or to remove hazardous parts. Second, sequence to collect individual materials efficiently are derived. If those sequences can be attached on each product, they can be referred in the reuse/recycle phases as useful information for efficient disassembly/cutting.
