6、99 National foreword This Part of BS4193 has been prepared under the direction of the Machine, Engineers and Hand Tools Standards Committee and forms part of a series, each Part dealing with an aspect of hardmetal insert tooling. The series implements corresponding International Standards in the dev
7、elopment of which the UK has played an active part. This Part of BS4193 is identical with ISO7848 “Shank type milling cutters for indexable insertsDesignation” which was revised and published in 1986 by the International Organization for Standardization (ISO) and was prepared by Technical Committee
8、ISO/TC29, Small tools. Terminology and conventions. The text of 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 especi
9、ally to the following. 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 ISO296, ISO297, ISO5413, ISO3002-1 and ISO7406, to which reference is made in the text and has decide
10、d 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 with a British Standard does not of itself confer immu
11、nity from legal obligations.

19、be used in any designation. Five symbols designate the characteristics of the body, two the characteristics of the shank, and four the method of holding and characteristics of the insert and the cutting length. In addition to the standardized designation (symbolse too a supplementary symbolp consist
20、ing of a maximum of two letters and/or numbers may 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 Inter
21、national Standard shall be made without consultation 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 o
22、r specifications.BS4193-16:1986 2 BSI 08-1999 The meaning of the eleven symbols constituting the code is as follows: Examples: End mill, with round inserts: Side and face cutting end mill, with inserts of various shapes and clearances: Milling cutter of special design, with square inserts: 4 Symbols
23、 4.1 Symbol for the cutter diameter Referencee The symbol for the cutter diameter is its effective cutting diameter, expressed in millimetres. The definition of the effective cutting diameter is given in the sketches of the table for the symbolf. e Number symbol identifying the cutter diameter (see4

NOTE 1Defined here is the effective number of slots, used to determine feed speed. For cutters of
30、 types G to L, 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. NOTE 2For milling cutters with more than one insert per slot, the direction of the flute helix shall be specified in the manufacturer

33、 length of the milling cutter minus the length of the parallel shank according to ISO3338 (see Figure 1); for milling cutters with Morse taper shank or with7/24shank: the protruding length is the distance from the face of the cutter to the gauge plane as defined in ISO296 and ISO297 respectively (se
34、e Figure 2 and Figure 3). The symbol for the protruding length is a three-digit number, equal to the nominal value of the protruding length. Example: Protruding length120mm, symbol120. If the protruding length is less than100mm, the symbol shall have as its first digit a zero. Example: Protruding le
