ISO 23704-3:2023

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.
