Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of

Introduction
A machine tool is a key device in manufacturing since it is used indispensably in the production
of machine parts used in various industrial areas. Many institutions have long been devoted to
technological development from the viewpoint of reducing downtime and defects and are considering
smart technologies such as the Internet-of-Things (IoT) as a new means to achieve this.
From the market perspective, there is a variety of so-called smart machine tools incorporating smart
technologies based on their own concepts using, e.g. local terminologies by machine tool builders
(MTBs), machine tool control, e.g. computerized numerical control (CNC) vendors, solution vendors
and service providers, which can be confusing to stakeholders, including end-users. For this and other
reasons, standards and substantial modelling for smart machine tool systems are needed.
1)
From the standards perspective, RAMI 4.0 (IEC PAS 63088) and IEC TR 63319 TR-SMRM provide a
reference model for Industry 4.0 and smart manufacturing on a high level. The ISO 23247 series defines
a generic framework to support the creation of a digital twin of observable manufacturing elements.
Furthermore, although some existing standards deal with Industry 4.0 enabling technologies, e.g. OPC-
UA (IEC/TR 62541-1), MTConnect (ANSI/MTC1.4-2018), ISO/IEC 30141, the IEC 62769 series, and many
machine tool standards from ISO TC39, no standard yet exists for smart machine tools for realizing
smart manufacturing / Industry 4.0 in the shop floor via cyber-physical systems (CPSs).
The ISO 23704 series specifies general requirements on smart machine tools for supporting smart
manufacturing in the shop floor via cyber-physical system control scheme, namely cyber-physically
controlled smart machine tool systems (CPSMT).
Figure 1 shows the overall structure of the ISO 23704 series, including:
— Overview and fundamental principles of a CPSMT in ISO 23704-1,
— Reference architecture of a CPSMT for subtractive manufacturing in ISO 23704-2, and
2)
— Reference architecture of a CPSMT for additive manufacturing in ISO 23704-3 .
Other related parts such as implementation guidelines or reference architectures for other types of
manufacturing will be added if and when necessary.
