Development of disassembly support system for mechanical parts and its application to design considering reuse/recycle

Recently, the design for disassemblabality/recyclability becomes more important from the viewpoint of Life Cycle Assessment or Emission-Minimum. Therefore, a disassembly support system which can be applied to the design considering reuse/recycle is developed. First, an algorithm for verifying disassemblability of parts as briefly explained. Next, a method for estimate the total number of feasible disassembly sequences without actually generating them is proposed. Furthermore, an order to reduce the number of disassembly sequences, precedence constraints such as the assembly feature are introduced. Finally, the efficiency of our developed disassembly sequence generation system is demonstrated and it is shown that the design can be evaluated from the viewpoint of disassemblability/recyclability by using our system.
