The work of preparing International Standards is normally carried out through
11、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
12、 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 crite
13、ria 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/directivesAttention is drawn to the possibility that some of the elements of this document may be the subject of patent

17、exable hardmetal (carbide) inserts with rounded corners, without fixing hole and with normal clearance of 0 and 11. These inserts are primarily intended to be mounted, by top clamping, on turning and boring tools.2 Normative referencesThe following documents, in whole or in part, are normatively ref

20、, with 0 normal clearance; TP: triangular inserts, with 11 normal clearance; SN: square inserts, with 0 normal clearance; SP: square inserts, with 11 normal clearance.Inserts with 0 normal clearance (TN and SN) are standardized only without chip breakers. Inserts with 11 normal clearance (TP and SP)
21、 are provided with and without chip breakers.At the time of publication, neither the shape nor the dimensions of chip breakers are standardized. Thus, if necessary, special features shall be explained by means of a diagram or additional specifications.Table C.1 gives the ranges of sizes for these in

25、ardmetal (carbide) inserts complying with this International Standard shall conform to ISO 1832.In addition to this designation, one or both of the following may be indicated: the symbol of the group of application, in accordance with ISO 513; the commercial designation of the hardmetal (carbide) gr
26、ade.5.2 MarkingThe following synnbol, at least, shall be marked on the insert itself (except when this would be difficult on the smaller inserts): symbol of the group of application, or commercial designation of the hardmetal (carbide) grade (or both, if possible, on large inserts).6 MeasurementAnne

It is strongly recommended that these standa
