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.
