Design for disassembly involves evaluating the ease/difficulty of disassembling a product composed of multiple components. Existing methods primarily address the problem of disassembly planning and do not quantify the ease or difficulty of disassembly. The current research work specifically addresses the development of a design for disassembly methodology based on the quantitative assessment (i.e. metrics) of the disassemblability of the product. The formulation of the metrics is based on the factors to be considered for disassembling a product. In particular we are considering the potential application of the methodology to robotic disassembly for recycling and maintenance. While designing a product it is necessary to determine the numerical value of the metric in order to arrive at an acceptable design. This facilitates the comparison of different design solutions. The methodology developed in this paper can serve as a basis for identifying the optimal design.
