Two-Dimensional Description Method of Process Information for 3D Assembly Instruction Publishing

Abstract

To deal with the complete description and quick search in 3D assembly instruction publishing, a Two-dimension description method of process information for 3D assembly instruction publishing was presented. Two-dimensional description model of process information is established from operation description and granularity by this method. In order to organize process information with a certain description stage, the concept of process information layer was proposed, and the describe structure for process information layers was been build based on similarity criteria. Subsequently, an abstract matrix representation method is provided to express 3D process information and build the assembly instructions publishing model. Abstract matrix representation method was the key to influence the 3D process information description, Therefore, In-depth researched on it and an instantiated matrix is given. Finally, an illustrative example is used to explain an application of the proposed approach.
