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. 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 on the ISO list of patent declarations received. www.iso.org/patents

The committee responsible for this document is Technical Committee ISO/TC 184, Automation systems and integration, Subcommittee SC 1, Physical device control.

ISO 14649 consists of the following parts, under the general title Automation systems and integration — Physical device control — Data model for computerized numerical controllers:

• Part 1: Overview and fundamental principles
• Part 10: General process data
• Part 11: Process data for milling
• Part 12: Process data for turning
• Part 13: Process data for wire electrical discharge machining (wire-EDM)
• Part 14: Process data for sink electrical discharge machining (sink-EDM)
• Part 111: Tools for milling machines
• Part 121: Tools for turning machines
• Part 201: Machine tool data for cutting processes [Technical Specification]

Gaps in numbering were intentionally left in order to allow further additions. ISO 14649-10 is the ISO 10303 Application Reference Model (ARM) for process-independent data. ISO 10303 ARMs for specific technologies are added after ISO 14649-10. ISO 14649 is harmonized with ISO 10303 in the common field of Product Data over the whole life cycle. ISO 14649-1 describes the different fields of standardization between ISO 14649, ISO 10303 and CNC manufacturers with respect to implementation and software development.

Introduction

ISO 14649-10 describes the general process data for numerical controlled machining and includes its schema. The subject of this schema (called machining_schema) is the definition of data types, which are generally relevant for different technologies (e.g. milling, turning, sink-EDM). It includes the definition of the workpiece, a feature catalogue containing features, which might be referenced by several technologies, the general executables and the basis for an operation definition. Not included in this schema are geometric items and presentations, which are referenced from the generic resources of ISO 10303, and the technology-specific definitions, which are defined in separate parts of ISO 14649.

ISO 14649-10 is not a stand-alone standard. Its implementation needs at least one additional technology-specific part (e.g. ISO 14649-11 for milling). This part of ISO 14649 describes sink Electrical Discharging Machining (sink-EDM) and it defines technology-specific data types representing the machining process for sink-EDM.

The main text of this part of ISO 14649 provides definitions and explanations of the data entities needed to provide control data information to an EDM controller.

The EXPRESS forms of the entities are given again in Annex A without the explanatory text for information.

Annex B provides an alternative view of these entities, with the different figures showing graphical representations of different elements. These figures are purely informative: a detailed explanation of the entities in the figures is given in the corresponding text definitions.

In addition, the schema uses machining features similar to ISO 10303-224. The description of process data is carried out using EXPRESS language as defined in ISO 10303-11. The encoding of the data is carried out using ISO 10303-21.

1 Scope

This part of ISO 14649 specifies the technology-specific data element needed as process data for sink-EDM. Together with the general process data described in ISO 14649-10, it describes the interface between computerized numerical controller and the programming system (i.e. CAM system or shop-floor programming system) for sink-EDM. It can be used for sink-EDM operations on this kind of machine.

The scope of this part of ISO 14649 does not include tools for any other technologies (e.g. turning, grinding). Tools for these technologies are described in other parts of ISO 14649.
