In order to maintain machines, there are more things to consider regarding disassembling operations than assembling ones. Therefore disassembling machines is a difficult operation, and making a mistake in the disassembling process may cause damage to machines and the injury of operators. In order to prevent these problems, parts list and operation manuals have been used. However, to deal with various situations, operators must have significant experience. If the machines have a million parts, the parts list includes one million lines, and many operation manuals are necessary. In order to solve these problems, a method is proposed for 3D visualization of connecting relations and illustrating the disassembling process. The description of connecting relations between parts was systematized; then, a method of inferring disassembling process was developed. Three conditions were considered for the inference of the disassembling process; parts should not fall off, parts should not become suspended, and some parts can be removed collectively as a unit. The disassembling process in which all parts meet these three conditions is inferred in this method. The method was implemented on a computer. A case study was conducted using the system, and it showed that a beginner operator can disassemble parts safely and smoothly by referring to the inferred process.
