9、4 Important remarks 4BS ISO 513:2012ISO 513:2012(E)ForewordISO (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
10、 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 Internationa
11、l 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 a
12、dopted 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 pa
13、tent rights. ISO shall not be held responsible for identifying any or all such patent rights.ISO 513 was prepared by Technical Committee ISO/TC 29, Small tools, Subcommittee SC 9, Tools with cutting edges made of hard cutting materials.This fourth edition cancels and replaces the third edition (ISO
14、513:2004), which has been technically revised.iv ISO 2012 All rights reservedBS ISO 513:2012ISO 513:2012(E)IntroductionThe variety of ways in which different manufacturers produce hard cutting materials with differing characteristics makes it impossible at the time of publication to standardize hard
15、 cutting materials graded in accordance with these characteristics.This International Standard is, therefore, limited to a classification of hard cutting materials based on their application and to a method of designation (colour marking and distinguishing symbols) for the main groups of application
16、 and the groups of application which constitute this classification.

17、nternational Standard specifies the classification and application of hard cutting materials, including hardmetals, ceramics, diamond and boron nitride, for machining by chip removal, and establishes their application.It is not applicable to other uses (mining and other percussion tools, wire drawin
18、g dies, tools operating by deformation of the metal and comparator contact tips, etc.).2 DesignationThe designation of groups of application for hard cutting materials includes the letter symbols in accordance with Tables 1 to 4, followed by a dash and the designation of the main group of chip remov

28、cation (see Table 5). They are divided according to the different workpiece materials which are to be machined. They are identified by a capital letter and an identifying colour.3.2 Groups of applicationEach main group of application is divided into application groups. The application groups are des
29、ignated by the letter for the main group and a classification number.The manufacturers of cutting material arrange in proper order their grades into the application group system according to the relative wear resistance and toughness of the grades (see Table 6).Table 6 shows that, according to this
30、International Standard, only “P” grades are thought to operate under conditions sufficiently arduous as to justify wear/toughness classification numbers 45 and 50. “M” and “K” grades may have classification numbers up to 40 and the remaining groups (N, S and H) may be allocated wear/toughness classi
31、fication numbers no greater than 30. Manufacturers may assign any available application code to a specified cutting tool material with qualifying composition.4 Important remarksA group of application is not identical to a cutting material grade. Grades from different manufacturers which are in the s
32、ame application group could be different as far as application range and performance level are concerned. Within an application group, a designation (eg “P01”) is not identical to a cutting material grade. Grades from different manufacturers with the same designation within an application group can
33、be different as far as composition, properties, application range and performance level are concerned. This International Standard, consequently, does not provide data for grade comparison charts.4 ISO 2012 All rights reservedBS ISO 513:2012BS ISO 513:2012ISO 513:2012(E) ISO 2012 All rights reserved
