The work of developing Internat
4、ional Standards is carried out through IS0 Technical Committees. Every Member Body interested in a subject for which a Technical Committee has been set up has the right to be represented on that Committee. International organizations, governmental and non-governmental, in liaison with ISO, also take
5、 part in the work. Draft International Standards adopted by the Technical Committees are circulated to the Member Bodies for approval before their acceptance as International Standards by the IS0 Council. Prior to 1972, the results of the work of the Technical Committees were published as IS0 Recomm
6、endations; these documents are now in the process of being transformed into International Standards. As part of this process, Technical Committee lSO/TC 29 has reviewed IS0 Recommendation R 514 and found it technically suitable for transformation. International Standard IS0 514 therefore replaces IS
7、0 Recommendation R 514-1966 to which it is technically identical. IS0 Recommendation R 514 was approved by the Member Bodies of the following countries : Australia Germany Austria Hungary Belgium India Brazil Italy Chile Korea, Rep. of Colombia Netherlands Czechoslovakia New Zealand Denmark Poland F

11、ide tips; it deals only with internal tools. External tools and the definition of right-hand and left-hand tools are the subject of IS0 243; designation and marking are the subject of IS0 504. The shank sections and the inserts used are selected respectively from those defined in IS0 241 and IS0 242

13、ypes of internal tools Only two types of internal tools, considered to be those most generally used, are provided for; they are tool No. 8 and tool No. 9, which differ from each other only in the shape of the end of the operative portion. Both types may be made either with a square shank or with a c
14、ylindrical shank, the front portion of the tool being of round section in both cases. Dimension I shown in the table is the nominal length of the carbide tip, type A or C, selected from those contained in IS0 242; this dimension is equal to approximately 0,6 d. 3.2 Shank sections For the particular
15、case of internal tools, only two types of sections are selected from among the various types provided for in IS0 241 : a) the square section h = b; b) the round section d. 3.3 Overall lengths Only one range of overall lengths is specified, the length being a function of the diameter d. The lengths a
16、re scaled approximately in the series of preferred numbers R 40/3 and are a practically linear expression in terms of d, no value departing by more than 15 mm from the value obtained with the formula : lOd+50mm. 3.4 Shape of the operative portion To permit the production of holes as small as possibl
17、e, a bend of 15” is specified for the operative portion, with a dimension n virtually equal to 0,4d and a cutting edge located at a distance equal to 0,2 d below the upper plane of the shank of the tool. 1 Copyright International Organization for Standardization Provided by IHS under license with IS
