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 ISO/IEC Directives, Part 3.
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 part of ISO 10303 may be the
subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.
International Standard ISO 10303-224 was prepared by Technical Committee ISO/TC 184,
Industrial automation systems and integration, Subcommittee SC 4, Industrial data. This second edition
cancels and replaces the first edition (ISO 10303-224:1999), of which it constitutes a technical
revision.
This International Standard is organized as a series of parts, each published separately. The structure of
this standard is described in ISO 10303-1. The numbering of the parts of this International Standard
reflects its structure:
— Parts 11 to 14 specify the description methods;
— Parts 21 to 29 specify the implementation methods;
— Parts 31 to 35 specify the conformance testing methodology and framework;
— Parts 41 to 50 specify the integrated generic resources;
— Parts 101 to 107 specify the integrated application resources;
— Parts 201 to 237 specify the application protocols;
— Parts 301 to 337 specify the abstract test suites;
— Parts 501 to 520 specify the application interpreted constructs.
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.
This International Standard 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.
This part of ISO 10303 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 may 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 the information requirements and the AIM. The short listing of the AIM specifies the interface
to the integrated resources and is given in 5.2. Note that the definitions and EXPRESS provided in the
integrated resources for constructs used in the AIM may include select list items and subtypes which are
not imported into the AIM. The expanded listing given in Annex A contains the complete EXPRESS
for the AIM without annotation. A graphical representation of the AIM is given in annex H. Additional
requirements for specific implementation methods are given in annex C.
Figure 1 contains the data planning model that provides a high level description of the requirements for
this application protocol. This planning model was created from the in-scope data from the activities of
the application activity model (AAM) and grouped into logical units of functionality. This planning
model is used as a guide in developing the application reference model (ARM).
This edition of this part of ISO 10303 incorporates modifications that are upwardly compatible with the
previous edition, and modifications that are not upwardly compatible with the previous edition.
Modifications to EXPRESS specifications are upwardly compatible if:
— the modifications do not result in changes to instances that are encoded according to ISO
10303-21; such instances conform to both the unmodified and modified EXPRESS specifications;
— the modifications do not result in changes to software that conforms to ISO 10303-22 with
respect to access to the data content of data structures;
— the modifications do not invalidate mappings to the previous edition of this part of ISO 10303
that are specified in the mapping table of an ISO 10303 application protocol.
Technical modifications that are upwardly compatible or are not upwardly compatible with ISO
10303-224:1999 are summarized in annex L. A brief summary of the modifications are the following:
— New Manufacturing_features which include Cutout, Recess, Rib_top, and Shape_profile;
— Enhancements to existing features and feature_definition_items which include Planar_face,
Ngon_profile, Ngon_base_shape, and new sub-type for Boss which is a Rectangular_boss;
— Increased scope from the manufacture of a single piece part to the manufacturing of an
assembly of piece parts;
— Modified Manufacturing_part_properties entities found in error in the first edition (ISO
10303-224:1999);
— Modified several information requirements and corresponding application interpreted model
entities to support harmonization with other application protocol;
— Normatively reference all of the current second edition and technical corrigendum parts of ISO
10303.
