Overview
ISO 23704-3:2023 - "General requirements for cyber-physically controlled smart machine tool systems (CPSMT) - Part 3: Reference architecture of CPSMT for additive manufacturing" defines a reference architecture for integrating cyber-physical principles into smart additive manufacturing (AM) systems. Building on ISO 23704-1, this standard describes the logical structure (not physical or implementation details) of a CPSMT for AM, covering the Smart Additive Manufacturing System (SAMS), the Cyber-Physically Controlled Machine tools (CPCM), the Cyber-Supporting System for Machine tools (CSSM), and their interfaces.
Key Topics
- Reference architecture: Logical layers and units that make up a CPSMT for AM, including AM Machine Units (AMU), CPS units, Data Processing Units (DPU), Digital Thread Unit, and MAPE (Monitoring, Analysis, Planning, Execution) unit.
- Technical requirements for SAMS: Requirements for autonomous handling of abnormalities, real-time (hard and soft) responses, data acquisition, processing, monitoring, prediction, diagnosis, decision-making, workflow updates, and interoperability.
- CPCM and CSSM functional views: Detailed functional breakdowns of machine-level control (inner-loop, intra-loop, inter-loop elements) and supporting cyber systems for data fusion, storage, transformation, and external interfaces.
- Digital thread concept: Data model and workflow management to maintain traceability across design, process, production, and post-processing in AM.
- Abnormality management: Types of AM abnormalities, detection, classification, and autonomous response strategies.
- Interface view and interoperability: Internal and external interfaces between CPCM, CSSM, shop-floor systems, humans, and higher-level hierarchy; emphasis on data schemas and interface management.
- Use cases and stakeholder requirements: Collected stakeholder needs, example scenarios, and practical application patterns included as informative annexes.
Applications
- Designing architecture for smart additive manufacturing platforms that require robust cyber-physical integration.
- Guiding system integrators and software vendors in building interoperable AM control and monitoring systems.
- Informing risk mitigation and real-time abnormality handling strategies in AM production lines.
- Establishing a digital thread for traceability, quality assurance, and lifecycle data management across AM processes.
Who should use this standard
- AM machine manufacturers and system integrators
- Industrial automation engineers and CPS designers
- Software vendors for AM monitoring, process control, and PLM/ERP integration
- Quality engineers and production managers implementing traceability and anomaly handling
- Standards bodies and researchers aligning CPSMT concepts for AM
