ISO 23704-2:2022

This document specifies a reference architecture of cyber-physically controlled smart machine tool systems (CPSMT) for subtractive manufacturing based on the reference architecture of a CPSMT as provided in ISO 23704-1. The reference architecture of a CPSMT for subtractive manufacturing includes: — the reference architecture of a cyber-physically controlled machine tool (CPCM), — the reference architecture of a cyber-supporting system for machine tools (CSSM), and — the interface architecture of a CPSMT. This document also provides: — a conceptual description of a shop floor device system (SFDS), — a conceptual description of a shop floor control system (SFCS), — a conceptual description of a unified interface system (UIS), and — example use cases of a reference architecture of a CPSMT for subtractive manufacturing. This document does not specify physical or implementation architecture.
