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.

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 10303-224 was prepared by Technical Committee ISO/TC 184, Industrial automation systems
and integration, Subcommittee SC 4 Industrial data.

This third edition of ISO 10303-224 cancels and replaces the second edition (ISO 10303-224:2001), of
which it constitutes a technical revision.

ISO 10303 is organized as a series of parts, each published separately. The structure of ISO 10303 is
described in ISO 10303-1.
Each part of ISO 10303 is a member of one of the following series: description methods, implementation
methods, conformance testing methodology and framework, integrated generic resources, integrated
application resources, application protocols, abstract test suites, application interpreted constructs, and
application modules. This part is a member of the 200 series.

A complete list of parts of ISO 10303 is available from the Internet:

Introduction
ISO 10303 is an International Standard for the computer-interpretable representation production
information and exchange of product data. The objective is to provide a neutral mechanism capable of
describing product data throughout the life cycle of a product, independent from any particular system.
The nature of this description makes it suitable not only for neutral file exchange, but also as a basis for
implementing and sharing product databases and archiving.

ISO 10303 is organized as a series of parts, each published separately. The parts of ISO 10303 fall into
one of the following series: description methods, integrated resources, application protocols, application
interpreted constructs, abstract test suites, implementation methods, and conformance testing. The series
are described in ISO 10303-1. This part of ISO 10303 is a member of the application protocol series.

ISO 10303-224 specifies an application protocol (AP) for the representation of information needed to
produce a mechanical part definition for process planning of a single piece or an assembly of piece parts
for machining operations, and specifies the integrated resources necessary to satisfy these requirements.

This application protocol defines the context, scope, and information requirements for the representation
of information needed to produce a mechanical part definition. These requirements specify the part
identification, tracking, shape, representation of the shape and material data necessary for the definition
of a part for process planning. The process planning function in an organization can be assisted a great
deal by identifying machining-oriented part shape features, so that the process planner can more readily
identify machining tools and processes to manufacture a part.

This application protocol identifies specific characteristics of part shape used in manufacturing. These
characteristics are used to define manufacturing features. These shapes can be represented either by
machining features defined in this application protocol, or by a boundary representation solid model,
shared by other application protocols and used as application interpreted constructs in this part. The
purpose of manufacturing features is to facilitate the identification of manufacturing shapes that are
human and computer interpretable. Manufacturing features allow information about the shape to be used
for decisions in computerized process planning systems.

Information about the part material is supplied so the process planning activity can determine equipment
and material requirements. Also supplied is administrative information necessary for tracking customer
information, supplier information about the part, and internal control information for the manufacturing
operation to support process planning. Tracking of certain administrative information is a component of
the iterative process for creating a process plan.

Application protocols provide the basis for developing implementations of ISO 10303 and abstract test
suites for the conformance testing of AP implementations.

Clause 1 defines the scope of the application protocol and summarizes the functionality and data covered
by the AP. Clause 3 lists the words defined in this part of ISO 10303 and gives pointers to words defined
elsewhere. An application activity model that is the basis for the definition of the scope is provided in
Annex F. The information requirements of the application are specified in Clause 4 using terminology
appropriate to the application. A graphical representation of the information requirements, referred to as
the application reference model, is given in Annex G.

Resource constructs are interpreted to meet the information requirements. This interpretation produces the
application interpreted model (AIM). This interpretation, given in 5.1, shows the correspondence between
