Abstract

Additive Manufacturing (AM) processes intertwine aspects of many different engineering-related disciplines, such as powder material metrology, design, in-situ and off-line measurements, control. Due to the increasing complexity of AM systems and processes, data cannot be shared among heterogeneous systems because of a lack of a common vocabulary and data interoperability methods. This paper aims to address insufficiencies in laser-based Powder Bed Fusion (PBF), a specific AM process, data representations to improve data management and reuse in PBF. Our approach is to formally decompose the processes and align PBF process-specifics with information elements as fundamental requirements for representing process-related data. The paper defines the organization and flow of process information. After modeling selected PBF processes and sub-processes as activities, we discuss possible more advanced requirements for the development of process data models that provide common terminology and process knowledge for managing data from various stages in AM.
