9、ion of small tools, including milling cutters, dates back as far as I9 16. Late in 1918 the American Engineering Standards Committee was organized and by 1920 ASME sponsorship had been sought and obtained for its efforts. During its early years, the interests of the Sectional Committee on Small Tool

10、s and Machine Tool Elements were concentrated on other parts of the standardization program; the manufacturers of milling cutters began the work by inaugurating a program of simplified practice under procedures set up by the U.S. Department of Commerce. A report of this activity was published in 192

11、5. Technical Committee No. 5, organized in 1927 to further the effort, by 1929 had completed a proposed standard, submitted it to and had it accepted by the Sectional Committee of the ASME and its two cosponsors, the National Machine Tool Builders Association and the Society of Automotive Engineers.

12、 Joint transmission of the proposed standard to the American Standards Association resulted in their grant of approval and recognition as an American Standard on April 8, 1930, with the designation ASA B5c-1930. Late in 1946, Sectional Committee BS instructed a reorganized TC5 to revise this standar

13、d, bring it into harmony with the American Standard for Machine Tapers (ASA BS.lO-1932), and enlarge its scope. On its completion in 1949 and approval by the Sectional Committee and its three cosponsor organizations (The Metal Cutting Tool Institute is the third), the revision was presented to the A

14、merican Standards Association. Designation as an American Standard was given on April 5, 1950. The document was designated ASA B5.3-1950. Again in 1956, TCS was reactivated, this time for the purpose of reviewing both ASA B5.3- 1950 and ASA BScl- 1947 (Nomenclature for Milling Cutter Teeth) for poss

15、ible revision and unification. As a result of the review, the decision was made to revise and unify, which involved such changes as: (a) deletion of all cutters not considered as standards; (b) inclusion of a nomenclature section made up of words and terms taken from ASA BScl-1947 and ASA B5.3-1950

16、(both the nomenclature section and glossary of terms) but restricted to elements of standard cutters only; (c) segregation and sectionalizing of tolerances on milling cutter dimensions plus the addition, for the first time, of a table of tolerances on the axial and radial runout of standard cutters.

17、 The resulting American Standard was approved on February 5, 1960; it was designated In 1962, Sectional Committee BS was divided, and the subject area of “Cutting Tools, Holders, Drivers, and Bushings” was assigned to new Sectional Committee B94, later renamed USA Standards Committee B94. Standardiz

18、ation of Milling Cutters was assigned to TCS of B94. Continuing developments in the milling cutter field, particularly a large expansion in the types of standard end mills, led to early reactivation of TCS for the purpose of reviewing and updating ASA B5.3-1960. The resulting new standard, ANSI B94.

19、19, was approved on May 27, 1968. ANSI B94.19- I968 incorporated several significant changes, such as: ASA B5.3-1960. . 111 (a) the increasing importance of end mills as a distinct category of cutting tools was recognized in the new title: “Milling Cutters and End Mills”; (6) dimensional standards f

20、or end mills were separated from those for conventional milling cutters and were presented in a separate section. Similarly, the tolerance tables for milling cutters and end mills were presented separately; (c) the nomenclature section was updated and at the same time it was made more compact throug

21、h deletion of unnecessary photographic illustrations. The 1977 revision follows the format developed for ANSI B94.19- 1968. Dimensional standards for milling cutters are covered by Tables 1-27, while Tables 28-65 cover end mills. These are followed by common milling cutter and end mill elements in T

22、ables 66- 69, and by milling cutter and end mill tolerances in Tables 70 and 71, respectively. In the revision, two new tables were added while five were deleted; of the remaining tables, about 25% were revised to some degree. The 1985 revision followed the 1977 format. Due to the addition of new Ta

23、bles 66-71, which gave dimensions and standard sizes for premium high speed steel end mills, the 1977 tables with these numbers were redesignated as Tables 72-77. The 1997 revision of this Standard follows the same format as the 1985 version with a few changes that were made to bring it into conform

24、ance with standard industry practice. Three tables were removed and dimensions for overall length were changed in eight of the tables. Tolerances were added to Table 74 for premium high speed steel end mills and adjustments were made to the tables to remove specifications for tools that are no longe

ASME B94.19-1997 was approved by the American National Standards Institute (ANSI) on September 25, 1997. iv ASME STANDARDS COMMITTEE B94 Cutting Tools, Holders, Drivers, and Bushings (The following is the roster of the Committee at the time of approval of this Standard.)
