Scope

This document specifies requirements and guidelines for implementing the reference architecture given in ISO 23704-2.
Specifically, this document specifies the implementation architecture (IA) including:

cyber-physically controlled machine tools (CPCM) for subtractive manufacturing (SM);
cyber-supporting system for machine tools (CSSM) for SM.

Also, this document provides implementation guidelines (IGs) including:

information model of CPSMT for SM;
communication model of CPSMT for SM;
integration model of CPSMT for SM.

As information, the following are included in the annexes:

systems engineering (SE) including SE-vee model and stakeholder requirements for SM (see Annex A);
use case of IA and IG of CPSMT for SM (see Annex B);
an implementation use case for CPSMT (see Annex C).
