16、:2014-05 7 3 Classification3.1 Main groups of applicationThere are six main groups of application (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 m

17、ain group of application is divided into application groups. The application groups are designated 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

18、resistance and toughness of the grades (see Table 6).Table 6 shows that, according to this 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 nu

19、mbers up to 40 and the remaining groups (N, S and H) may be allocated wear/toughness classification 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 id

20、entical to a cutting material grade. Grades from different manufacturers which are in the same 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. Gra

21、des from different manufacturers with the same designation within an application group can 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.DIN ISO 513:2014-05 8
