Abstract: The invention concerns a method and system for manufacturing a three-dimensional part by a computer-aided manufacturing process, and an associated method and system for detecting a manufacturing process breach in a computer-aided manufacturing process of a three-dimensional part.
The three-dimensional part manufacturing comprises computing pedigree information (10) relating to the manufacturing process of the three-dimensional part, wherein the pedigree information (10) gives access to pedigree data of the manufacturing process of the three-dimensional part, the pedigree data comprising manufacturing data (8D) collected during the manufacturing process of the three-dimensional part, and inserting a mark (20) encoding the pedigree information on a surface or within a volume of the three-dimensional part, to obtain a marked three-dimensional part (24).
The detection of manufacturing process breach comprises pedigree data (42) retrieval from a marked three-dimensional part and determining whether a manufacturing breach occurred by applying classifying means to the retrieved pedigree data.
