National foreword

This British Standard is the UK implementation of ISO 13444:2012.

The UK participation in its preparation was entrusted to Technical Committee TDW/4, Technical Product Realization.

A list of organizations represented on this committee can be obtained on request to its secretary.

This publication does not purport to include all the necessary provisions of a contract. Users are responsible for its correct application.

Compliance with a British Standard cannot confer immunity from legal obligations.

This British Standard was published under the authority of the Standards Policy and Strategy Committee on 31 August 2012.

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 13444 was prepared by Technical Committee ISO/TC 10, Technical product documentation, Subcommittee SC 6, Mechanical engineering documentation.

Introduction

This International Standard covers knurling on workpieces with standardized diametral pitches. It does not deal with the knurling tools; these are outside the scope of ISO/TC 10.

This International Standard includes dimensional relations for straight and diamond knurling on cylindrical surfaces having teeth of uniform pitch parallel to the axis of the cylinder or at a helix angle of 30° with the axis of work.

The knurling is made by displacement of the material on the surface of a workpiece when rotated under pressure against a knurling tool.

The recommendations given are applicable for general purposes. They are intended to improve the uniformity and appearance of knurling, reduce the production of defective work, as well as decrease the number of tools required.

In Annex A, an alternative method of dimensioning and indication of knurling is presented. This method uses a module for the calculation of the knurling. Note that this method requires different knurling tools than those used in the method presented in the main body of this International Standard.

1 Scope

This International Standard specifies a series of knurling dimensions intended for general use in mechanical engineering and is intended to avoid an unnecessary multiplicity of tools by restricting the profile angle to 90° and by restricting the selection of diametral pitches.
