General requirements for cyber-physically controlled smart machine tool systems (CPSMT) — Part 3: Reference architecture of CPSMT for additive manufacturing

This document specifies a reference architecture of cyber-physically controlled smart machine tool systems (CPSMT) for additive manufacturing (AM) based on the reference architecture of CPSMT as provided in ISO 23704-1 and the requirements for cyber-physically controlled smart additive manufacturing system.

The reference architecture of a CPSMT for AM includes:

— the technical requirements for the smart additive manufacturing system (SAMS),

— the reference architecture of the cyber-physically controlled machine tools (CPCM) for AM,

— the reference architecture of the cyber-supporting system for machine tools (CSSM) for AM, and

— the interface view of the CPSMT for AM.

This document also provides:

— stakeholder requirements for the SAMS,

— the concept of the digital thread,

— types of abnormality in AM, and

— use cases of reference architecture of a CPSMT for AM.

This document does not specify physical or implementation architecture.
