Description

Disassembly has achieved significant attention in the past few years for its pivotal role in waste recycling, remanufacturing and servicing of components for maintenance. With more emphasis on products to be environmentally safe, today, the need for efficient and cost effective disassembly process has gained momentum. This thesis studies the current approaches in sub-assembly detection, disassembly sequencing and path planning and proposes methodologies that tend to better approach disassembly processes applicable to any manufacturing industry. Literature review indicates less importance shed on sub-assembly detection that could expedite the process of disassembly sequencing several fold. An algorithm for automatic sub-assembly detection and its application in disassembly sequencing has been presented. The disassembly sequencing involves the use of interference matrices and AND/OR logical operations that could be implemented into a computer program. This makes it easier for future integration with CAD systems. Having determined the disassembly sequence, a scheme using alternating sum of volumes with partitioning (ASVP), form feature decomposition (FFD) and Gaussian hemisphere (GHS) has been proposed for determining disassembly directions in three-dimensional space. The algorithms presented would significantly enhance disassembly processes in the industry. Advisors/Committee Members: Anand, Dr. Sundararaman.
