9、ardization of small tools,including milling cutters,dates back as far as 1916.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 Too
10、ls 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 1925.
11、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.Joint tr
12、ansmission 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-l 930.Late in 1946,Sectional Committee B5 instructed a reorganized TC5 to revise this standard,bring it i
13、nto harmony with the American Standard for Machine Tapers(ASA B5.l0-l 932),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 American Standards
14、 Association.Designation as an American Standard was given on April 5,1950.The document was designated ASA B5.3-l 950.Again in 1956,TC5 was reactivated,this time for the purpose of reviewing both ASA B5.3-1950 and ASA B5cl-l947(Nomenclature for Milling Cutter Teeth)for possible revision and unificat
15、ion.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 ASAB5cl-l947 and ASA B5.3-1950(both the nomenclature section and
16、glossary of terms)but restricted to elements of standard cutters only;(c)segregation and sectionalizing of tolerances on milling cutter dimensions plus theaddition,for the first time,of a table of tolerances on the axial and radial runout of standard cutters.The resulting American Standard was approved on February 5,1960;it was designated ASA B5.3-I 960.In 1962,Sectional Committee B5 was divided,and the subject area of Cutting Tools,Holders,Drivers,and Bushings was assigned to new Sectional Comm
