Disassembly planning with consideration of rotational motions
Abstract
In this research we try to identify and solve the problems of disassembly planning for assembly, recycling, repair and maintenance. Assembly planning requires assemblability analysis which usually employs disassembly planning. In order to recycle or repair a certain component of a used product, we need to disassemble it from the product. The automation of the disassembly operations is highly anticipated with increasing emphasis on the environmental impact of post-use products. We break down the disassembly operations into separation, traveling, alignment, and exiting stages. This model simplifies the analysis of the disassemblability of components and helps obtain collision-free disassembly paths. The disassembly paths include not only translational but also rotational motions; the latter are not well solved in the literature. The proposed three disassembly sequencing algorithms generate (1) a single sequence for the fast assemblability analysis, (2) multiple sequences for a whole product in the layer-by-layer fashion, and (3) goal-oriented sequences for a target component to be recycled or repaired, respectively. They are conceptually simple yet meaningful to achieve the objectives: disassembly planning for assembly, recycling, repair and maintenance.
