ISO 23704-1:2022

Overview

ISO 23704-1:2022 - "General requirements for cyber-physically controlled smart machine tool systems (CPSMT) - Part 1: Overview and fundamental principles" defines the concept, reference architecture and fundamental principles for cyber-physically controlled smart machine tool systems (CPSMT). It specifies the key components, interfaces and capabilities of a CPSMT, provides background and the concept of a shop floor device system (SFDS), and includes example use cases. This part does not prescribe physical or implementation architecture.

Keywords: ISO 23704-1:2022, CPSMT, cyber-physical, smart machine tools, reference architecture, SFDS, CSSM, CPCM, digital twin, Industry 4.0

Key topics and technical requirements

• Reference architecture of a CPSMT: Defines the primary and associated system decomposition (CPCM, CSSM, SFDS, SFCS, UIS) and their roles in smart machine tool systems.
• Core components and terms: Formalizes terms such as cyber-physically controlled machine tool (CPCM), cyber-supporting system for machine tool (CSSM), shop floor device system (SFDS), shop floor control system (SFCS), unified interface system (UIS), and digital twin.
• Interfaces and interoperability: Details interfaces between CPCM and CSSM, SFDS and SFCS, and the role of UIS for lifecycle, hierarchy level and human interaction.
• Capabilities and behavior: Describes expected CPSMT capabilities including autonomous abnormality handling, autonomous coordination with shop-floor devices, collaboration with shop-floor control systems, lifecycle and hierarchy interfacing, and stakeholder support.
• Conformance and goals: Guidance on conforming to the CPSMT reference architecture and high-level objectives to support smart manufacturing on the shop floor.
• Informative content: Background on CPSMT, SFDS mapping to Industry 4.0 concepts (administration shell), and example use cases to illustrate architecture application.

Practical applications and intended users

ISO 23704-1 is intended as a high-level standard and practical guideline for:

• Design engineers and system architects planning cyber-physical machine tools
• Machine tool builders (MTBs) and CNC/control vendors integrating CPS features
• Software engineers developing CSSM functions and digital twins
• Solution and service providers delivering Industry 4.0 shop-floor systems
• Factory operators and end users evaluating smart machine tool capabilities

Use cases include designing interoperable smart machine tools, specifying shop-floor interfaces, defining digital-twin interactions for monitoring/analysis, and planning autonomous abnormality handling strategies.
