Symbols and may be used when n

30、ecessary.For tipped inserts in accordance with ISO 16462 and ISO 16463, the designation code comprises 12 symbols for designating the dimensions and other characteristics; symbols to as well as and shall be used in every designation. Symbols , and may be used when necessary. Symbols and shall be sep

31、arated by a dash as shown in Clause 4, example 2.In addition to the standardized designation for indexable inserts and tipped inserts, a supplementary symbol consisting of one or two characters may be added by the manufacturer for a better description of his/her product (for example, different chip

32、breakers), provided this symbol is separated from the standardized designation by a dash and that it does not contain letters specific to references , and .Indexable inserts for cutting tools Designation DIN ISO 1832:2017-06 6 No addition to or extension of the designations specified in this documen

33、t shall be made without consultation with ISO/TC 29 and without its agreement. Rather than adding symbols not provided for in this system, it is preferable to add all necessary explanations in the form of detailed sketches or specifications to the designation in accordance with this document.However

34、, if the letter symbol “X” is used in position 4 of the designation, it is allowed to use, in positions 5, 6 and 7, symbols representing values not appearing in this document, but which shall be described explicitly using the sketch or the detailed specifications given in 5.4.The significance of the

35、 symbols constituting the designation code is as follows: Letter symbol identifying insert shape (see 5.1)Compulsory symbols for indexable insertsCompulsory symbols for tipped inserts according to ISO 16462 and ISO 16463, except as noted Letter symbol identifying normal clearance (see 5.2) Letter sy

41、 the assumed working plane, Pf, is perpendicular to the reference plane, Pr, and is parallel to the assumed direction of feed motion. This plane is defined only in the case of inserts having one or more wiper edges.The assumed direction of feed motion is taken parallel to the considered wiper edge (
