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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
In other circumstances, particularly when there is an urgent market requirement for such documents, a
technical committee may decide to publish other types of document:
 an ISO Publicly Available Specification (ISO/PAS) represents an agreement between technical experts in
an ISO working group and is accepted for publication if it is approved by more than 50 % of the members
of the parent committee casting a vote;
 an ISO Technical Specification (ISO/TS) represents an agreement between the members of a technical
committee and is accepted for publication if it is approved by 2/3 of the members of the committee casting
a vote.
An ISO/PAS or ISO/TS is reviewed after three years in order to decide whether it will be confirmed for a
further three years, revised to become an International Standard, or withdrawn. If the ISO/PAS or ISO/TS is
confirmed, it is reviewed again after a further three years, at which time it must either be transformed into an
International Standard or be withdrawn.
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.
ISO/TS 14649-201 was prepared by Technical Committee ISO/TC 184, Automation systems and integration,

Introduction
Modern manufacturing enterprises are built from facilities spread around the globe, which contain equipment
from hundreds of different manufacturers. Immense volumes of product information need to be transferred
between the various facilities and machines. Today's digital communications standards have solved the
problem of reliably transferring information across global networks. For mechanical parts, the description of
product data has been standardized by ISO 10303, leading to the possibility of using standard data throughout
the entire process chain in the manufacturing enterprise.
Impediments to realizing this principle are the data formats used at the machine level. Most computer
numerical control (CNC) machines are programmed in the ISO 6983 “G and M code” language. Programs are
typically generated by computer-aided manufacturing (CAM) systems that use computer-aided design (CAD)
information. However, ISO 6983 limits program portability for the following three reasons:
a) the language focuses on programming the tool centre path with respect to machine axes, rather than the
machining process with respect to the part;
b) the standard defines the syntax of program statements, but in most cases leaves the semantics
ambiguous;
c) vendors usually supplement the language with extensions that are not covered in the limited scope of
ISO 6983.
ISO 14649 is a new model of data transfer between CAD/CAM systems and CNC machines, which replaces
ISO 6983. It remedies the shortcomings of ISO 6983 by specifying machining processes rather than machine
tool motion, using the object-oriented concept of workingsteps. Workingsteps correspond to high-level
machining features and associated process parameters. CNCs are responsible for translating workingsteps
into axis motion and tool operation. A major benefit of ISO 14649 is its use of existing data models from
ISO 10303. As ISO 14649 provides a comprehensive model of the manufacturing process, it can also be used
as the basis for a bi- and multi-directional data exchange between all other information technology systems.
ISO 14649 represents an object-oriented, information- and context-preserving approach for numerical control
(NC) programming that supersedes data reduction to simple switching instructions or linear and circular
movements. As it is object- and feature-oriented and describes the machining operations executed on the
workpiece, rather than machine dependent axis motions, it will be running on different machine tools or
controllers. This compatibility will spare all data adaptations by post-processors if the new data model is
correctly implemented on the NC controllers. If old NC programs in ISO 6983 are intended to be used on such
controllers, the corresponding interpreters will need to be able to process the different NC program types in
parallel.
In developing ISO 14649, a gradual evolution from ISO 6983 programming to portable feature-based
programming has been envisaged. Early adopters of ISO 14649 will certainly support data input of legacy “G
and M codes” manually or through programs, just as modern controllers support both command-line interfaces
and graphical user interfaces. This is likely to be made easier as open-architecture controllers become more
prevalent. Therefore, ISO 14649 does not include legacy program statements, which would otherwise dilute its
effectiveness.
The information form in ISO 14649 already allows for major improvements over existing methods, but in order
to support even more efficient production, a description of the manufacturing environment will be needed in
addition to the manufacturing information. Consequently, this part of ISO 14649 is a first step to permitting the
description of machine tools as a manufacturing resource. The description allows process planners to
describe their machine needs for a micro-process plan (an ISO 14649 file), referred to as a requirements
model. The model also allows existing machine tools to be described as resources for manufacturing, referred
to as catalogue models. This part of ISO 14649 is intended to provide a basis for process planning and
simulation, for controller developers and for machine tool developers to describe their products, as well as for
research, for example. This part of ISO 14649 is not intended to replace existing standards for machine tool
descriptions, but to provide the information necessary for manufacturing applications in a concise way. It is
envisaged that there will be a continuing effort to describe the manufacturing resource environment in a
standardized manner, so as to support efficient advanced and flexible manufacturing.
