The work of pr
11、eparing 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, i
12、n 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/I
13、EC 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

17、sions 1 Scope This International Standard specifies the dimensions of indexable 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 r
18、eferences The following documents, in whole or in part, are normatively referenced in this document and are indispensable to its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies
19、. ISO 513, Classification and application of hard cutting materials for metal removal with defined cutting edges Designation of the main groups and groups of application ISO 1832, Indexable inserts for cutting tools Designation 3 Types of insert The types of indexable hardmetal (carbide) inserts spe
20、cified in this International Standard are the following: TN: triangular inserts, 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 stand
21、ardized only without chip breakers. Inserts with 11 normal clearance (TP and SP) 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 diag
22、ram or additional specifications. Table C.1 gives the ranges of sizes for these inserts. 4 Interchangeability 4.1 Tolerances Indexable hardmetal (carbide) inserts specified in this International Standard are, provided in the following tolerance classes, in accordance with ISO 1832: a) inserts withou
23、t chip breakers: tolerance classes U and G; b) inserts with chip breakers: tolerance class M. Inserts with chip breakers and tolerance class G are second preference (see Annex C). The values of the tolerances in accordance with ISO 1832 are given in Annex A. ISO 2013 All rights reserved 1BS ISO 883:
24、2013ISO 883:2013(E) Other tolerances are given in Tables 1 and 2. 4.2 Thickness, s, of inserts with chip breakers The thickness, s, of inserts with chip breakers is defined as the distance between the cutting edge at the corner and the opposing supporting surface of the insert; see Figure 1 a) and 1
25、 b). a) b) Figure 1 5 Designation and marking 5.1 Designation The designation of the indexable hardmetal (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
26、application, in accordance with ISO 513; the commercial designation of the hardmetal (carbide) grade. 5.2 Marking The 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 desi
27、gnation of the hardmetal (carbide) grade (or both, if possible, on large inserts). 6 Measurement Annex B indicates the methods of measuring the dimension m of the indexable inserts covered by this International Standard. 7 Recommended dimensions 7.1 General The choice of the more common dimensions i
28、s restricted to the specifications given in Tables 1 and 2. It is strongly recommended that these standard inserts be used wherever possible (first preference). When other inserts are specially required, insert dimensions shall be selected from the unshaded 2 ISO 2013 All rights reservedBS ISO 883:2

38、3:2013(E) Annex B (informative) Method of measurement of “m” dimension NOTE This annex forms an integral part of this International Standard. B.1 Triangular inserts Dimension m is related to the side opposite the corner that is to be measured. The insert is placed on a surface plate, as shown in Fig
39、ure B.1, and checked by means of a dial gauge zeroed with the aid of a gauge block corresponding to dimension m. The dial gauge then gives a direct reading of the error when applied to the inserts to be measured. Figure B.1 B.2 Square inserts Dimension m is checked by reference to the diameter d of
40、a precision roller, where d corresponds to the nominal diameter of the inscribed circle of the insert. The insert is mounted on a 90 vee-block, as shown in Figure B.2, and checked by means of a dial gauge which has been zeroed to dimension m by means of a roller with the aid of a gauge block. The di
41、al gauge then gives a direct reading of the error when applied to the inserts to be measured. The roller has a tolerance of 0,002 mm.8 ISO 2013 All rights reservedBS ISO 883:2013ISO 883:2013(E) Figure B.2 ISO 2013 All rights reserved 9BS ISO 883:2013ISO 883:2013(E) Annex C (informative) Inserts with
