5、 coverBS 4193-22:1996 ii BSI 11-1998 National foreword This British Standard has been prepared by Technical Committee MTE/18 and is identical with ISO 10910:1995 Classification and designation of approximate chip control zones for indexable inserts with chipbreakers, prepared by ISO/TC 29, Small too

6、ls, of the International Organization for Standardization (ISO). The Technical Committee has reviewed the provisions of ISO 683-1:1987, ISO3002-1:1982, ISO 3002-3:1984 and ISO 3685:1993 to which normative reference is made in the text, and has decided that they are acceptable for use in conjunction

7、with this standard. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations. Cross-reference Publi

This will be indicated in the amendment table on theinside front cover.BS 4193-22:1996 BSI 11-1998 1 1 Scope This International Standard establishes a graph format used

10、 to develop diagrams depicting chipbreaker indexable insert performance. Performance results may be derived from the cutting test described in clause 5. Classification zones are established and coded in this International Standard. Suppliers of chipbreaker insert products may classify their products

11、 using the code of the zone within which the primary use of their product is indicated. It is important to acknowledge that the relationships established by diagrams developed according to this International Standard may vary from one work material to another, as well as with other machining variabl

12、es, and that it is not the purpose of this International Standard to serve as a specific guide to the practical application of chipbreaker insert products, but rather grant the user a sort of pre-selection, on a general level, that will allow him to look at only those items that have the best chance

13、 of satisfying his needs. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this International Standard. At the time of publication, the editions indicated were valid. All standards are subject to revision, and parties t

The limits of the feed and depth of cut shall be = 0,025 mm/rev to 2,5 mm/rev and a p= 0,1 mm to 16 mm. 4 Diagrams The graph (see Figure 1) may be used to develop diagrams depicting chipbreaker inser

18、t performance resulting from the standard cutting test. The diagram shall be constructed by connecting points on the graph and shall represent an area within which chips are controlled. Referring to chips as acceptable and/or unacceptable is not recommended due to the varied opinions from industry t

19、o industry. Recommended terms are: controlled and uncontrolled. Also, it would be acceptable to use chip form codes established in ISO3685:1993, annex G, or to show the actual chips generated from the cutting test. 5 Cutting test The cutting test developed to establish chipbreaker insert performance

20、 and subsequent classification is described as follows: Operation: external (outside diameter) turning. Cutting edge angle (according to ISO 3002-1): k r= 75 for insert shape S or k r= 90 to 95 for insert shapes C, D, T and V. Workpiece material: C 45 (according to ISO683-1:1987). Materials other th

21、an C 45 shall be indicated in the insert performance diagram. Normalized:180 HB to 200 HB. Cutting Speed (according to ISO 3002-1): appropriate to cutting material. Cutting speed shall be indicated in the insert performance diagram. Minimum diameter of parts:100 mm.BS 4193-22:1996 2 BSI 11-1998 Figu

22、re 1BS 4193-22:1996 BSI 11-1998 3 6 Classification The term classification used in this International Standard is defined as the common ground on which suppliers can specify the primary use of their chipbreaker inserts. The range of use of a chipbreaker insert on the other hand is shown by a diagram

23、 generated on the graph, Figure 1. The diagram (see Figure 2) is divided into 6 zones of classification. It is the responsibility of the supplier to classify his chipbreaker insert with the code of the zone that best represents the intended primary use of the insert being classified (only one letter

24、 shall be used). While the zones are specified by this International Standard, it should be noted that the decision to create the zones in this manner is arbitrary. Each zone has its own code, either A, B, C, D, E or F which may be used at the discretion of the chipbreaker insert supplier. However,

25、the classification codes defined here shall not be used as an addition to the existing insert identification systems (see ISO 1832) or as commercial designations for chipbreaker insert products. NOTE 1It is common practice in industry that manufacturers classify inserts with certain geometry feature

26、s in “family geometry groups”, designated by letters, numbers or a combination of both after the standard designation of the insert, e.g.: CNMG 120408 XX Although those inserts (“XX”) are grouped to belong to the same geometry family the chip control features can be different, depending on the size

27、of the insert and the size of the corner radii. This International Standard provides the possibility of giving information about chip breaking capabilities of insert sizes within a certain geometry family, for instance as follows: Insert designation Chip control zone CNMG 120404 XX A CNMG 160616 XX
