An efficient method for exploded view generation through assembly coherence data and precedence relations

Purpose Three-dimensional exploded view is a schematic representation of a product anticipated for performing assembly or disassembly operations. Exploded view is found in many applications, such as product instructional materials, repair and maintenance handbooks. This paper aims to propose an efficient exploded view generation technique based on assembly coherence data and disassembly feasibility testing, and illustrate it on various configurations of assemblies. Design/methodology/approach The proposed methodology extracts the assembly contact information between the constituent parts and geometric feasibility relation matrix based on the common mating surface of part pairs in liaison and assembly collision detection. These data are further used for exploded view generation. Findings The proposed exploded view generation method determines the possible disassembly sequences and simplifies the procedure in determining the number of disassembly levels. Research limitations/implications The procedure consumes more time for the products with large number of part counts having numerous non-ruled surfaces. Originality/value The proposed method is effectively used to solve assemblies, where parts are assembled through oblique orientations. The method is found successful in generating exploded view for products with large number of parts through collision-free paths.
