The series implements corresponding International Standards in the development of which the UK has played an active part
7、. This Part of BS4193 is identical with ISO7406 “Bore type milling cutters for indexable inserts Designation” which was published in1986 by the International Organization for Standardization (ISO) and was prepared by Technical Committee ISO/TC29, Small tools. Terminology and conventions. The text of
8、 the International Standard has been approved as suitable for publication as a British Standard without deviation. Some terminology and certain conventions are not identical with those used in British Standards; attention is drawn especially to the following. The comma has been used as a decimal mar
9、ker. In British Standards it is current practice to use a full point on the baseline as the decimal marker. Wherever the words “International Standard” appear, referring to this standard, they should be read as “Part of BS4193”. The Technical Committee has reviewed the provisions of ISO3002-1:1982 t
10、o which reference is made in the text and has decided that they are acceptable for use in conjunction 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 wi

15、pecifications for such tools. It covers the designation of face milling cutters, side and face (slotting) milling cutters, shell end mills as well as simple designs of slab milling cutters. 2 References ISO1832, Indexable (throwaway) inserts fur cutting tools Designation Code of symbolization.

ISO7848, Shank type milling cutters for indexable inserts Designation. 3 Explanation of the code The code consists of eleven symbols of which the first ten symbols shall be used in any designation. The last symbol shall be used only for side and face (slotting) milling cutters
18、, shell end mills and slab milling cutters. Four symbols designate the characteristics of the body and seven the clamping and characteristics of the inserts. In addition to the standardized designation (symbols e to o), a supplementary symbolp consisting of a maximum of two letters and/or numbers ma
19、y be added by the manufacturer after the standardized designation for a better description of his products, subject to this symbol being separated from the standardized designation by a dash. No addition to or extension of the code given in this International Standard shall be made without consultat
20、ion with technical committee ISO/TC29 and its agreement. Rather than adding symbols not provided for in this system, it is preferable to add to the designation conforming to this International Standard any necessary explanations in detailed sketches or specifications. The meaning of the eleven symbo
21、ls constituting the code is as follows: Examples: Face milling cutter: e Number symbol identifying the cutter diameter (see4.1). Symbols for the characteristics of the body f Letter symbol identifying the type of cutter and the type and/or size of the attachment (see4.2). g Number symbol identifying
22、 the number of slots (see4.3). h Letter symbol identifying cutting direction (see4.4). Dash (not counted as a symbol). i Letter symbol identifying the method of holding the insert (see4.5). Symbols for clamping and characteristics of the inserts j Number symbol identifying insert cutting edge angle
23、(see4.6). k Letter symbol identifying the insert shape (see4.7). l Letter symbol identifying the normal clearance of insert (see4.8). m Number symbol identifying the indexable insert size (see4.9). n Letter symbol identifying the normal clearance of the wiper edge (see4.10). o Number symbol identify
24、ing the cutting width of side and face milling cutters or of slab milling cutters (see4.11). p Symbol for the manufacturer, at his option. e f g h i j k l m n 250C C 20 R W 75 S N 12 P BS4193-17:1989 2 BSI 10-1999 Side and face milling (slotting) cutter: 4 Symbols 4.1 Symbol for the cutter diameter
25、Referencee The number symbol for the cutter diameter is a two- or three-digit number equal to the cutting diameter in millimetres. 4.2 Symbol for the type of cutter and for the type and/or size of the attachment Referencef 4.3 Symbol for the number of slots Referenceg The number symbol is also the n
26、umber of slots. NOTEDefined here is the effective number of slots used to determine feed speed. It does not always correspond to the real total number of slots on the tool, because of the staggered disposition of the inserts on the milling cutter. One-digit values are to be preceded by0 (zero); for
27、example for eight slots, the symbol is08. e f g h i j k l m n o 160 H 18 N F 90 T P 16 P 20 Letter symbol Type and/or size of the attachment Type of cutter A Tenon drive, hexagon socket head cap screw (type A in ISO6462) B Tenon drive, cutter retaining screw (type B of ISO6462) C Centring arbor havi

37、earance of the wiper edge of the insert Referencen If the milling cutter is equipped with inserts having different wiper normal clearances, the wiper symbol shall be X. NOTEFor milling cutters designed to receive indexable inserts without wiper edges (e.g.milling cutters with round inserts), referen
38、cen is not used. However, if referenceo has to be specified by a symbol, referencen will be represented by a dash (). 4.11 Symbol for the cutting width of side and face (slotting) milling cutters, shell end mills and slab milling cutters Referenceo The number symbol is a two- or three-digit number e
39、qual to the nominal cutting width in millimetres (disregarding any decimals) of side and face (slotting) milling cutters, shell end mills and of slab milling cutters. For cutting widths smaller than10mm, the first digit shall be0 (zero). Example: NOTEThe possibility of adjusting the cutting width of
40、 side and face milling cutters shall be indicated in the catalogues for these tools. The nominal width is in this case the mean value of the adjusting range. Insert type Number symbol Equilateral and equiangular (H, O, P, S, T) and equilateral and non-equiangular (C, D, E, M, V, W) The designation s
41、ymbol for the insert size is the side length, disregarding any decimals. Example: Edge length: 16,5mm Symbol of designation: 16 Non-equilateral and equiangular (L) and non-equilateral and non-equiangular (A, B, K) The designation symbol for the insert size is always given for the major or the longer
42、 cutting edge. The designation symbol is the length, disregarding any decimals. Example: Length of the major cutting edge: 19,5mm Symbol of designation: 19 Round insert (R) The designation symbol for the insert size is always given for the diameter value disregarding any decimals. Example: Diameter:
43、 15,875mm Symbol of designation: 15 NOTEWhen the symbol resulting from the value has only one digit, it shall be preceded by0 (zero).
