Structure mapping method from EBOM to PBOM

Abstract

The invention provides a structure mapping method from an EBOM to a PBOM, and the method comprises the steps: traversing all child nodes in an original BOM structure tree through calling a bottom-layer traversal algorithm API, and obtaining the structure attribute information of all child parts in the EBOM; judging whether the part type corresponding to each sub-part is a dummy part, a middle partor an outsourcing part according to the structure attribute of each sub-part in the BOM structure; acquiring hierarchical information of each sub-part, and outputting three-dimensional space coordinates of the current sub-part according to a three-dimensional coordinate generation rule; substituting the three-dimensional space coordinates of the current sub-part into a mapping matrix corresponding to the part type of the current sub-part for mapping, and outputting new hierarchical coordinates; and establishing a PBOM structure by the obtained new hierarchical coordinates according to the coordinates and the BOM structure corresponding rule, and completing the complete mapping process of the BOM structure. According to the method, the PBOM structure can be automatically constructed, and the readability of the BOM is improved.

Description

technical field [0001] The invention relates to the field of three-dimensional process design, in particular to a structure mapping method from EBOM to PBOM. Background technique [0002] The constituent elements of the BOM are mainly divided into two parts, the structure and attributes of the BOM ontology. The BOM structure describes the composition and construction relationship of the product. It is the organizational framework supporting the entire BOM and builds a bridge for the transmission and update of product data flow. BOM attributes include product process attribute information, tooling resources, processing process information, product assembly process information, etc. The mapping between attribute information determines the speed and accuracy of process information data flow in the product life cycle. Therefore, analyzing the BOM mapping relationship needs to be carried out simultaneously from the structural layer and the attribute layer. [0003] With the deve...
