Industrial automation systems and integration — Numerical control systems for machine tools — Part 2: Requirements for numerical control system integration
This document specifies requirements for the integration of numerical control systems (NC systems). It consists of technical and inspection requirements and test methods. This document is applicable to all machine tools using NC systems not already covered by class C standards (including metal cutting machine tools, metal forming machine tools and woodworking machine tools) and for partial assemblies of machine tools (including cabinets and auxiliary devices) intended to be integrated into machine tools. It is also applicable to other production equipment using NC systems. NOTE NC system integration with machine tools is performed mainly by machine tool builders using an NC system to control their machine tools, system integrators by assembling machine tools with the NC system to a production line, and machine tool users by upgrading their existing equipment.

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
any patent rights identified during the development of the document will be in the Introduction and/or

ISO 23218-2:2022(E)
Introduction
Numerically controlled machine tools are effective production assets with an operations stock of more
than four million units and still increasing.
While mechanical construction sets the base for accuracy and durability, the numerical control system
(NC system) is the enabler to leverage the potential of the system.
The NC system comprises a powerful computing hardware, a sophisticated NC-Kernel, and an
elaborated connectivity, stretching from internal process parameters to high level manufacturing
execution system (MES) integration and beyond. It supports operation concepts from push buttons to
sophisticated touch-panel systems.
Machine tools and their NC systems are used in harsh environments facing operational conditions such
as vibrations, dirt, coolant spray and electromagnetical interferences. Purchasers and operators of
machine tools require confidence on the appropriate quality, durability and usability in order to ensure
intended use and productivity.
The ISO 23218 series addresses requirements for NC systems. This document provides requirements
for NC system integration, and ISO 23218-1 specifically provides requirements for the NC system itself.
Expected users of this document include:
— design engineers working for a company that uses an NC system for machine tools, for developing a
new and/or improving a current NC system for machine tools;
— design engineers working for a machine tools builder company, for developing and providing new
and/or improving current machine tools by procuring an NC system;
— facility planning engineers, for procuring new and/or improving current machine tools with an NC
system.

1 Scope
This document specifies requirements for the integration of numerical control systems (NC systems). It
consists of technical and inspection requirements and test methods.
This document is applicable to all machine tools using NC systems not already covered by class C
standards (including metal cutting machine tools, metal forming machine tools and woodworking
machine tools) and for partial assemblies of machine tools (including cabinets and auxiliary devices)

NC systems.
NOTE NC system integration with machine tools is performed mainly by machine tool builders using an NC
system to control their machine tools, system integrators by assembling machine tools with the NC system to a

3.1
numerical control system
NC system
system that realizes the automatic control of a process by using numerical data introduced while the
operation is in progress
Note 1 to entry: Driving devices are not included in NC systems.
3.2
port
access to a device or network of a numerical control system (NC system) (3.1) where electromagnetic
energy or signals may be supplied or received or where the device or network variables may be
observed or measured
Note 1 to entry: The port generally refers to the boundary on the external interface of the NC system, and
interface generally refers to the boundary of each unit in an NC system.
