Digital Twin in Metal Materials Manufacturing
In metal manufacturing, components with highest quality requirements are produced for many aspects of life. Therein a sequence of manufacturing processes has to be managed with defined quality gates along the process chain. For this reason, specifications upon that sufficiently describe the condition of material batches are agreed between customers and suppliers.
This paper will provide an overview of possible modelling approaches that are required to create digital twins of components along manufacturing and supply chains, namely #1 Ontology for heat treatment process nitriding, #2 Physical modeling for martensite transformation and #3 Statistical method for quality assurance.
The application of a digital representative of the manufacturing and quality assurance chain hereby shows a high potential for further efficiency improvements.
